When a scientist makes an educated guess that attempts to explain an observation or answer a question, he forms a:
- A.
Theory
- B.
Law
- C.
Hypothesis
Correct Answer
C. HypothesisExplanation
When a scientist makes an educated guess to explain an observation or answer a question, it is referred to as a hypothesis. A hypothesis is a proposed explanation based on limited evidence or prior knowledge that can be tested through further experimentation or observation. It is a preliminary step in the scientific method and serves as a starting point for further investigation. Unlike a theory or a law, a hypothesis is not yet proven and requires further testing and evidence to support or reject it.Rate this question:

Organisms that produce their own food are called:
- A.
Producers
- B.
Consumers
- C.
Decomposers
Correct Answer
A. ProducersExplanation
Organisms that produce their own food are called producers. This is because they have the ability to convert sunlight energy into chemical energy through the process of photosynthesis. They are typically plants, algae, and some types of bacteria. These organisms are at the base of the food chain and provide energy for other organisms in the ecosystem. Consumers, on the other hand, obtain their energy by consuming other organisms, while decomposers break down dead organic matter.Rate this question:

Organisms that break down the dead remains of other organisms are called:
- A.
Producers
- B.
Consumers
- C.
Decomposers
Correct Answer
C. DecomposersExplanation
Decomposers are organisms that break down the dead remains of other organisms. They play a crucial role in the ecosystem by recycling nutrients and returning them to the environment. Decomposers, such as bacteria and fungi, break down organic matter into simpler compounds, which can then be used by other organisms. Unlike producers, which convert sunlight into energy, and consumers, which obtain energy by consuming other organisms, decomposers primarily obtain their energy from breaking down dead organic material.Rate this question:

An educated guess that has been tested with a significant amount of data becomes a:
- A.
Theory
- B.
Law
- C.
Hypothesis
Correct Answer
A. TheoryExplanation
An educated guess that has been tested with a significant amount of data becomes a theory. The process of testing a hypothesis with extensive data and evidence can lead to the development of a theory. A theory is a well-substantiated explanation of a phenomenon that has been repeatedly tested and supported by evidence. It is a more advanced stage of understanding compared to a hypothesis, which is an initial educated guess that is yet to be extensively tested. A law, on the other hand, is a statement that describes a phenomenon but does not explain why it occurs, unlike a theory.Rate this question:

- 5.
Once a theory has been tested by and is consistent with generations of data, it becomes a:
- A.
Law
- B.
Hypothesis
- C.
Fact
Correct Answer
A. LawExplanation
Once a theory has been tested by and is consistent with generations of data, it becomes a law. This is because a law is a scientific principle that has been proven to be true through repeated experimentation and observation. It is a well-established and widely accepted explanation for a natural phenomenon. In contrast, a hypothesis is a proposed explanation that has not yet been tested or proven, while a fact is a statement that can be verified and proven to be true.Rate this question:

An abrupt and marked change in the DNA of an organism compared to that of its parents is:
- A.
Metabolism
- B.
Mutation
- C.
Heterotroph
Correct Answer
B. MutationExplanation
Mutation refers to an abrupt and marked change in the DNA of an organism compared to that of its parents. It can occur spontaneously or be induced by external factors such as radiation or chemicals. Mutations can lead to variations in traits and genetic diversity within a population. These changes can have both positive and negative effects on an organism's survival and reproductive success.Rate this question:

Living creatures that are too small to see with the naked eye are called:
- A.
Microorganisms
- B.
Macroorganisms
- C.
Autotrophs
Correct Answer
A. MicroorganismsExplanation
Microorganisms are living creatures that are too small to see with the naked eye. They include bacteria, viruses, fungi, and protozoa. These organisms play important roles in various ecosystems and can have both positive and negative impacts on human health. Macroorganisms, on the other hand, are larger organisms that can be seen without the need for magnification. Autotrophs are organisms that can produce their own food through photosynthesis or chemosynthesis.Rate this question:

The process by which physical and biological characteristics are transmitted from the parent(s) to the offspring:
- A.
Reproduction
- B.
Inheritance
- C.
Mutation
Correct Answer
B. InheritanceExplanation
Inheritance refers to the process by which physical and biological characteristics are passed down from parent(s) to their offspring. This involves the transmission of genetic information, such as DNA, from one generation to the next. Through inheritance, traits and characteristics, such as eye color, hair texture, and susceptibility to certain diseases, can be inherited by offspring from their parents. This process is fundamental in shaping the genetic makeup and traits of individuals and populations over time.Rate this question:

Reproduction accomplished by a single organism is called:
- A.
Asexual
- B.
Sexual
- C.
Autotrophic
Correct Answer
A. AsexualExplanation
Reproduction accomplished by a single organism is called asexual. In asexual reproduction, a single organism can produce offspring without the involvement of another organism. This can occur through various methods such as binary fission, budding, or vegetative propagation. Asexual reproduction allows for rapid population growth and the transmission of favorable traits from one generation to the next. Unlike sexual reproduction, which requires the fusion of gametes from two parents, asexual reproduction only involves one parent.Rate this question:
-
- 10.
A parent and two offspring are studied. Although there are many similarities between the parent and offspring, there are also some differences. How do they reproduce?
- A.
Autotrophically
- B.
Sexually
- C.
Asexually
Correct Answer
B. SexuallyExplanation
The parent and offspring in this study reproduce sexually. This means that they require the fusion of gametes (reproductive cells) from two individuals to produce offspring. Sexual reproduction involves the combination of genetic material from both parents, resulting in genetic variation among the offspring. This explains the observed similarities and differences between the parent and offspring, as they share some traits but also exhibit variations. Autotrophic reproduction refers to the ability to produce their own food, which is not relevant to this context. Asexual reproduction involves the production of offspring without the involvement of gametes or genetic recombination, which is not applicable here.Rate this question:

This scientist developed the 5-kingdom system of classification, which is the one used by most highschool and college biology courses.
- A.
Louis Pasteur
- B.
Anton Leeuwenhoek
- C.
Carl Linnaeus
Correct Answer
C. Carl LinnaeusExplanation
Carl Linnaeus is the correct answer because he is the scientist who developed the 5-kingdom system of classification. This system is widely used in high school and college biology courses to categorize living organisms into five main kingdoms: Animalia, Plantae, Fungi, Protista, and Monera. Linnaeus is also known as the father of modern taxonomy and his work laid the foundation for the classification and naming of species that is still used today.Rate this question:

This type of cell has distinct, membrane-bounded organelles:
- A.
Prokaryotic
- B.
Eukaryotic
- C.
Nukaryotic
Correct Answer
B. EukaryoticExplanation
Eukaryotic cells are the only type of cells that have distinct, membrane-bounded organelles. These organelles, such as the nucleus, mitochondria, and endoplasmic reticulum, are enclosed within their own membranes, separating them from the rest of the cell. Prokaryotic cells, on the other hand, lack these membrane-bound organelles and have a simpler internal structure. The term "nukaryotic" is not a recognized term in cell biology and is likely a misspelling or error. Therefore, the correct answer is eukaryotic.Rate this question:

This type of cell has NO distinct, membrane-bounded organelles:
- A.
Prokaryotic
- B.
Eukaryotic
- C.
Nukaryotic
Correct Answer
A. ProkaryoticExplanation
Prokaryotic cells do not have distinct, membrane-bounded organelles. Unlike eukaryotic cells, which have a nucleus and various organelles, prokaryotic cells lack these structures. Instead, their genetic material is located in the nucleoid region, which is not enclosed by a membrane. Prokaryotic cells also lack other membrane-bound organelles such as mitochondria, endoplasmic reticulum, and Golgi apparatus, which are present in eukaryotic cells. Therefore, the correct answer is prokaryotic.Rate this question:

The idea that long ago, very simple life forms suddenly appeared through chemical reactions is called:
- A.
Evolution
- B.
Abiogenesis
- C.
Spontaneous generation
Correct Answer
B. AbiogenesisExplanation
Abiogenesis refers to the concept that simple life forms originated from non-living matter through chemical reactions. This idea suggests that life on Earth could have emerged from organic molecules, such as amino acids, combining and forming more complex structures over time. Abiogenesis is different from evolution, which explains the process of how life forms change and diversify over generations. Spontaneous generation, on the other hand, is a disproven theory that claimed living organisms could arise spontaneously from non-living matter.Rate this question:

An organism is multicellular with eukaryotic cells and is a decomposer. To what kingdom does it belong?
- A.
Animalia
- B.
Fungi
- C.
Plantae
Correct Answer
B. FungiExplanation
The organism described in the question is multicellular with eukaryotic cells and is a decomposer. Fungi are the only kingdom that fits this description. Fungi are multicellular organisms with eukaryotic cells that obtain nutrients by decomposing organic matter. Animalia and Plantae are not decomposers, so they are not the correct answer.Rate this question:

The science of classifying organisms is called:
- A.
Taxonomy
- B.
Binomial nomenclature
- C.
Biology
Correct Answer
A. TaxonomyExplanation
Taxonomy is the correct answer because it refers to the scientific discipline that involves classifying and categorizing organisms based on their characteristics and evolutionary relationships. It involves organizing organisms into hierarchical groups or taxa, such as kingdom, phylum, class, order, family, genus, and species. Binomial nomenclature, on the other hand, is a specific naming system used in taxonomy to give each species a unique two-part scientific name. Biology is a broader field that encompasses the study of living organisms, including their structure, function, growth, evolution, and distribution.Rate this question:

Organisms that eat only organisms other than plants:
- A.
Herbivores
- B.
Carnivores
- C.
Omnivores
Correct Answer
B. CarnivoresExplanation
Carnivores are organisms that eat only other organisms, specifically animals. They do not consume plants as a part of their diet. This distinguishes them from herbivores, which eat only plants, and omnivores, which consume both plants and animals. Therefore, the correct answer is carnivores.Rate this question:
-

Organisms that eat both plants and other organisms:
- A.
Herbivores
- B.
Carnivores
- C.
Omnivores
Correct Answer
C. OmnivoresExplanation
Omnivores are organisms that eat both plants and other organisms. Unlike herbivores, which only consume plants, and carnivores, which only consume other animals, omnivores have a varied diet that includes both plant matter and other organisms. This flexibility allows them to adapt to different environments and food sources, making them highly adaptable and versatile in their feeding habits.Rate this question:

This man finally demonstrated, in 1859, that microorganisms cannot spontaneously generate:
- A.
John Needham
- B.
Lazzarro Spallanzani
- C.
Louis Pasteur
Correct Answer
C. Louis PasteurExplanation
Louis Pasteur is the correct answer because he conducted experiments that disproved the theory of spontaneous generation. His experiments involved using swan-necked flasks filled with broth, which were heated to kill any existing microorganisms. Pasteur observed that no growth occurred in the flasks, even after long periods of time, unless the necks of the flasks were broken, allowing microorganisms from the air to enter. This demonstrated that microorganisms do not spontaneously generate, but rather come from preexisting microorganisms in the air. Pasteur's experiments were instrumental in establishing the principles of modern microbiology.Rate this question:

The idea the living organisms can come from non-living matter is called:
- A.
Evolution
- B.
Spontaneous generation
- C.
Abiogenesis
Correct Answer
B. Spontaneous generationExplanation
Spontaneous generation refers to the idea that living organisms can arise spontaneously from non-living matter. This concept was widely accepted in the past but has been disproven by scientific experiments. It was believed that maggots could arise from rotting meat or mice could appear from piles of grain. However, the experiments conducted by Louis Pasteur in the 19th century demonstrated that living organisms only come from pre-existing living organisms. This led to the rejection of spontaneous generation and the acceptance of biogenesis, the principle that life arises from other living organisms.Rate this question:

Special structures that allow living organisms to sense the conditions of their internal or external environment:
- A.
Sensors
- B.
Feelers
- C.
Receptors
Correct Answer
C. ReceptorsExplanation
Receptors are special structures in living organisms that enable them to sense and detect the conditions of their internal or external environment. These receptors can be found in various parts of the body and are responsible for receiving and transmitting signals to the brain or nervous system, allowing organisms to respond and adapt to changes in their surroundings. They play a crucial role in helping organisms perceive and interact with their environment, ensuring their survival and well-being.Rate this question:

Organisms that eat living producers and/or consumers for food are called:
- A.
Producers
- B.
Consumers
- C.
Decomposers
Correct Answer
B. ConsumersExplanation
Consumers are organisms that obtain their food by eating other living organisms, whether they are producers (organisms that can produce their own food through photosynthesis) or other consumers. They play a crucial role in the food chain by transferring energy and nutrients through different trophic levels. Unlike producers, consumers cannot produce their own food and rely on consuming other organisms to meet their energy and nutritional needs. Decomposers, on the other hand, break down dead organic matter and recycle nutrients back into the ecosystem.Rate this question:

What is binomial nomenclature?
- A.
The science of classifying organisms
- B.
Naming an organism with its genus and species names
- C.
Naming an organism with its kingdom and phylum names
Correct Answer
B. Naming an organism with its genus and species namesExplanation
Binomial nomenclature is the practice of naming an organism using its genus and species names. This system was developed by Carl Linnaeus in the 18th century as a way to provide a standardized and universal method for identifying and categorizing living organisms. By using binomial nomenclature, scientists can communicate clearly and precisely about different species, ensuring that each organism has a unique and specific name that reflects its evolutionary relationships and characteristics. This naming system is widely used in the field of biology and helps to organize and classify the vast diversity of life on Earth.Rate this question:

An organism is classified as a carnivore. Please check all that apply.
- A.
Autotroph
- B.
Heterotroph
- C.
Producer
- D.
Consumer
- E.
Decomposer
Correct Answer(s)
B. HeterotropH
D. ConsumerExplanation
The organism being classified as a carnivore indicates that it obtains its energy by consuming other organisms, making it a heterotroph. Additionally, carnivores are consumers as they feed on other organisms. Autotrophs, on the other hand, produce their own energy through photosynthesis or chemosynthesis, which does not apply to carnivores. Producers are also autotrophs, so this does not apply to the carnivore. Decomposers break down dead organic matter, which is not mentioned in the question. Therefore, the correct answers are heterotroph and consumer.Rate this question:

An organism that is able to make its own food is called a(n):
- A.
Autotroph
- B.
Heterotroph
- C.
Herbivore
Correct Answer
A. AutotropHExplanation
An organism that is able to make its own food is called an autotroph. Autotrophs are capable of producing their own organic compounds through processes like photosynthesis or chemosynthesis. They convert inorganic substances, such as sunlight or chemicals, into organic molecules that can be used as a source of energy. This ability to synthesize their own food sets autotrophs apart from heterotrophs, which rely on consuming other organisms for their energy needs. Herbivores, on the other hand, are a type of heterotroph that feed exclusively on plants.Rate this question:

Science has no limitations.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
The statement "Science has no limitations" is incorrect. While science is a powerful tool for understanding and explaining the natural world, it does have limitations. Science is based on empirical evidence and is subject to change as new evidence emerges. Additionally, there are certain phenomena that science may not be able to fully explain or understand, such as consciousness or the origin of the universe. Therefore, it is not accurate to say that science has no limitations.Rate this question:

Reproduction that requires two organisms:
- A.
Asexual
- B.
Sexual
- C.
Inheritance
Correct Answer
B. SexualExplanation
Sexual reproduction requires two organisms because it involves the fusion of gametes from two different individuals to create offspring. This process allows for genetic variation and diversity in the population. In contrast, asexual reproduction only involves one organism, where offspring are produced through mitosis or budding, resulting in genetically identical clones of the parent organism. Inheritance refers to the passing on of genetic traits from one generation to the next, which is a fundamental aspect of sexual reproduction.Rate this question:
