Which of the following is not a criteria for life?
A.
Contains DNA
B.
Extracts and converts energy
C.
Senses and responds to change
D.
Can regulate body temperature
Correct Answer
D. Can regulate body temperature
Explanation The ability to regulate body temperature is not a criteria for life because there are many organisms that are able to survive and thrive in extreme temperatures without the ability to regulate their body temperature. These organisms, such as bacteria and certain types of plants, are able to adapt to their environment and function without the need for temperature regulation. Therefore, while temperature regulation may be important for certain organisms, it is not a universal requirement for life.

Of the following, which is not a step in the scientific method?
A.
Observation
B.
Proof
C.
Experimentation
D.
Data Collection
Correct Answer
B. Proof
Explanation The scientific method involves a series of steps used to investigate and understand phenomena. These steps typically include making observations, conducting experiments, and collecting data. However, "proof" is not a step in the scientific method. In science, proof is not a definitive concept, as new evidence can always emerge to challenge or refine existing theories. Instead, scientists aim to gather evidence and support their hypotheses through experimentation and data collection, continually seeking to improve our understanding of the natural world.

Pasteur's experiment proves that microorganisms
A.
Are not transported in air
B.
Cannot spontaneously generate
C.
Will grow in a flask with a curved neck stopper
D.
Can grow from non-living material
Correct Answer
B. Cannot spontaneously generate
Explanation Pasteur's experiment involved a curved neck flask that allowed air to enter but prevented dust and microorganisms from entering. He boiled the liquid inside the flask, killing any existing microorganisms. Over time, no microorganisms grew in the flask, indicating that they did not spontaneously generate. This experiment provided evidence against the theory of spontaneous generation, which suggested that microorganisms could arise from non-living material. Therefore, the correct answer is "cannot spontaneously generate."

Which of the following would be considered a mutation?
A.
Parents and child have blue eyes
B.
Offspring cannot metabolize sugar, but parents can
C.
Both parents and child have freckles
D.
Offspring is blonde and parents are brunette
Correct Answer
B. Offspring cannot metabolize sugar, but parents can
Explanation The given answer, "offspring cannot metabolize sugar, but parents can," would be considered a mutation. A mutation refers to a change in the genetic material of an organism, resulting in a different characteristic or trait. In this case, the inability of the offspring to metabolize sugar, while the parents can, indicates a mutation in the offspring's genetic makeup. This mutation likely affects the genes responsible for sugar metabolism, leading to a difference in this trait between the offspring and its parents.

The correct order for classifying groups is
A.
Kingdom, Phylum, Order, Class, Family, Genus, and Species
B.
Order, Kingdom, Family, Class, Genus, Phylum, and Species
C.
Kingdom, Phylum, Class, Order, Family, Genus, and Species
D.
Genus, Species, Class, Order, Family, Kingdom, and Phylum
Correct Answer
C. Kingdom, pHylum, Class, Order, Family, Genus, and Species
Explanation The correct order for classifying groups is Kingdom, Phylum, Class, Order, Family, Genus, and Species. This is known as the Linnaean system of classification, which is widely used in biology to organize and categorize living organisms. The system starts with the broadest category, Kingdom, and then narrows down to more specific categories, such as Phylum, Class, Order, Family, Genus, and finally Species. This hierarchical structure allows scientists to group organisms based on their similarities and evolutionary relationships.

Kingdom Monera contains organisms which have
A.
Exclusively prokaryotic cells
B.
Highly specialized tissues
C.
organelles within their cells
D.
Exclusively eukaryotic cells
Correct Answer
A. Exclusively prokaryotic cells
Explanation The correct answer is "exclusively prokaryotic cells." This means that all organisms in the Kingdom Monera have cells that lack a nucleus and other membrane-bound organelles. Prokaryotic cells are simpler in structure compared to eukaryotic cells, which have a nucleus and various organelles. Therefore, the organisms in the Kingdom Monera do not possess highly specialized tissues or organelles within their cells, and they are not composed of eukaryotic cells.

Which of the following is false about the Kingdom Protista?
A.
Contains organisms which are microscopic
B.
Members include the amoebae and paramecia
C.
Organisms are heterotrophic
D.
Cannot produce their own food
Correct Answer
D. Cannot produce their own food
Explanation The Kingdom Protista includes organisms that are microscopic and members such as amoebae and paramecia. These organisms are heterotrophic, meaning they cannot produce their own food. This makes the statement "cannot produce their own food" true about the Kingdom Protista.

Which of the following applies to man?
A.
Is heterotrophic
B.
Is classified a producer
C.
Eats dead remains of organisms
D.
Is exclusively herbivore
Correct Answer
A. Is heterotropHic
Explanation The correct answer is "is heterotrophic". Heterotrophic refers to organisms that obtain their energy by consuming other organisms. This means that man, like other animals, relies on consuming other living organisms for sustenance.

Which of the following is true of asexual reproduction?
A.
DNA is exchanged
B.
Requires two organisms
C.
Requires a single parent
D.
Traits are a combination of both parents
Correct Answer
C. Requires a single parent
Explanation Asexual reproduction is a type of reproduction that involves only one parent. In this process, the parent organism produces offspring that are genetically identical to itself. There is no exchange of DNA between two organisms, and traits are not a combination of both parents. Asexual reproduction is commonly seen in organisms such as bacteria, fungi, and plants, where new individuals are formed through methods like budding, fragmentation, or spore formation. This allows for rapid reproduction and colonization of new habitats.

An organism is classified as a decomposer. Is it an autotroph or heterotroph?
Correct Answer heterotroph
Explanation Since the organism is classified as a decomposer, it means that it obtains its energy by breaking down and consuming dead organic matter. This indicates that the organism relies on external sources for its nutrition, making it a heterotroph. Autotrophs, on the other hand, are able to produce their own food through processes like photosynthesis.

Which cells contain distinct, membrane-bound organelles, prokaryotic cells or eukaryotic cells
Correct Answer eukaryotic cells eukaryotic
Explanation Eukaryotic cells contain distinct, membrane-bound organelles. This means that within eukaryotic cells, there are various specialized compartments enclosed by membranes, such as the nucleus, mitochondria, endoplasmic reticulum, Golgi apparatus, and lysosomes. These organelles perform specific functions and are essential for the cell's overall structure and function. On the other hand, prokaryotic cells lack these distinct membrane-bound organelles and instead have a simpler internal structure. Therefore, the correct answer is eukaryotic cells.
