What domain(s) consist(s) of prokaryotes?
Correct Answer
Bacteria ArchaeaExplanation
Prokaryotes are single-celled organisms that lack a nucleus and other membrane-bound organelles. They are divided into two domains: Bacteria and Archaea. Bacteria are the most well-known prokaryotes and are found in various environments, including soil, water, and the human body. Archaea, on the other hand, are often found in extreme environments such as hot springs, deep-sea hydrothermal vents, and salt flats. Both Bacteria and Archaea play crucial roles in various ecological processes and have distinct genetic and biochemical characteristics.Rate this question:
- 6.
List the 3 domains.
Correct Answer
Bacteria Archaea EukaryaExplanation
The answer provided lists the three domains of life, which are Bacteria, Archaea, and Eukarya. These domains represent the highest level of classification for all living organisms. Bacteria and Archaea are both prokaryotic domains, consisting of single-celled organisms without a nucleus, while Eukarya is the domain that includes all eukaryotic organisms, which have cells with a nucleus. This answer accurately identifies the three domains, providing a concise and correct response to the question.Rate this question:

Order, Regulation, Growth and development, Energy utilization, Reaction to environment, Reproduction, EvolutionExplanation
The given answer includes all the properties/traits of a living thing. These properties include order, regulation, growth, energy utilization, reaction to the environment, reproduction, and evolution. The repetition of the properties in the answer does not affect the correctness of the answer as it still includes all the necessary traits.Rate this question:

What are the building blocks of DNA?
Correct Answer
A, G, C, TExplanation
The building blocks of DNA are nucleotides, which consist of four different bases: adenine (A), guanine (G), cytosine (C), and thymine (T). These bases form the genetic code that determines the characteristics and functions of living organisms. Each DNA strand is made up of a sequence of these bases, with A always pairing with T and G always pairing with C. This pairing allows DNA to replicate and transmit genetic information accurately during cell division and protein synthesis.Rate this question:
- 10.
Is DNA found in the nucleus of prokaryotic cells? Yes or No? Explain.
Correct Answer
NoExplanation
Prokaryotic cells do not have a nucleus.Rate this question:
- 11.
All organisms consist of more than one cell.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
The statement is false because not all organisms consist of more than one cell. There are single-celled organisms, such as bacteria and protozoa, that are composed of only one cell. These organisms are capable of carrying out all the necessary functions of life within a single cell. Multicellular organisms, on the other hand, are composed of multiple cells that work together to form tissues, organs, and organ systems.Rate this question:

What is the name of the heritable material found in the nucleus of eukaryotic cells?
Correct Answer
DNAExplanation
DNA, or deoxyribonucleic acid, is the correct answer to the question. DNA is the heritable material found in the nucleus of eukaryotic cells. It carries the genetic instructions for the development, functioning, and reproduction of all living organisms. DNA is composed of nucleotides, which are made up of a sugar, a phosphate group, and a nitrogenous base. The sequence of these bases in DNA determines the genetic code and the traits of an organism.Rate this question:
- 13.
All organisms, including bacteria, yeast, and insects are composed of cells.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
All organisms, regardless of their complexity, are made up of cells. This is a fundamental principle in biology known as the cell theory. Cells are the basic structural and functional units of life, and they are responsible for carrying out all the necessary processes for an organism to survive and thrive. Bacteria, yeast, and insects are all examples of organisms that are composed of cells. Therefore, the statement that all organisms, including bacteria, yeast, and insects, are composed of cells is true.Rate this question:

- 14.
Give two examples of producers and two examples of consumers.
Correct Answer
Trees, Flowers, Humans, AnimalsExplanation
This answer is correct because it provides two examples of producers (trees and flowers) and two examples of consumers (humans and animals). Producers are organisms that can make their own food through photosynthesis, while consumers are organisms that obtain energy by consuming other organisms. Trees and flowers are examples of producers because they can produce their own food through photosynthesis. Humans and animals are examples of consumers because they obtain energy by consuming plants or other animals.Rate this question:
- 15.
Compare the function of producers and consumers.
Correct Answer
Producers are photosynthetic organisms like plants and consumers are the ones that eat the plants.Explanation
The explanation provided correctly compares the function of producers and consumers. It states that producers, such as plants, are photosynthetic organisms that can produce their own food through the process of photosynthesis. On the other hand, consumers are organisms that obtain their energy by consuming other organisms, specifically plants in this case. This explanation highlights the distinction between the two roles in an ecosystem, where producers are the primary source of energy and consumers depend on them for their survival.Rate this question:
- 16.
Which major type of cell has many membrane bound organelles?
- A.
Prokaryotic
- B.
Eukaryotic
Correct Answer
B. EukaryoticExplanation
Eukaryotic cells have many membrane-bound organelles, such as the nucleus, mitochondria, endoplasmic reticulum, Golgi apparatus, and lysosomes. These organelles are enclosed by a lipid bilayer membrane, which helps compartmentalize different cellular processes and allows for specialized functions within the cell. In contrast, prokaryotic cells lack membrane-bound organelles and their genetic material is not enclosed within a nucleus.Rate this question:
-
- 17.
What are the two major kinds of cells?
Correct Answer
Prokaryotic EukaryoticExplanation
The two major kinds of cells are prokaryotic and eukaryotic. Prokaryotic cells are simple and do not have a nucleus or membrane-bound organelles. They are found in bacteria and archaea. On the other hand, eukaryotic cells are more complex and have a nucleus and membrane-bound organelles. They are found in plants, animals, fungi, and protists.Rate this question:
- 18.
The dynamics of any ecosystem depend on two main processes. What are they?
Correct Answer
Cycling of nutrients.
The flow of energy from sunlight to producers to consumers to decomposers.Explanation
The dynamics of any ecosystem depend on the cycling of nutrients, which involves the movement and transformation of essential elements such as carbon, nitrogen, and phosphorus through various living organisms and their environment. This process ensures that nutrients are continuously recycled and available for different organisms to use. Additionally, the flow of energy from sunlight to producers (plants) through photosynthesis, and then to consumers (animals) and decomposers (bacteria and fungi) through feeding and decomposition, is crucial for sustaining life in an ecosystem. This energy flow allows organisms to perform essential functions, grow, reproduce, and maintain their populations.Rate this question:
- 19.
What gas do the leaves of plants take in?
- A.
Hydrogen Peroxide
- B.
Carbon
- C.
Carbon Dioxide
- D.
Photosynthesis
Correct Answer
C. Carbon DioxideExplanation
The correct answer is Carbon Dioxide. During photosynthesis, plants take in carbon dioxide from the atmosphere through tiny openings in their leaves called stomata. Carbon dioxide is an essential component for plants to produce glucose and oxygen through the process of photosynthesis. Hydrogen peroxide is not a gas that plants take in, and carbon is not the gas that plants primarily use for photosynthesis.Rate this question:
-
- 20.
What is the term for food production in green plants?
Correct Answer
PhotosynthesisExplanation
Photosynthesis is the correct answer because it refers to the process by which green plants convert sunlight, carbon dioxide, and water into glucose and oxygen. This process occurs in the chloroplasts of plant cells and is essential for the production of food in plants. Through photosynthesis, plants are able to capture energy from the sun and convert it into chemical energy, which is stored in the form of glucose. This glucose serves as a source of energy for the plant and is also used to produce other organic compounds necessary for growth and development.Rate this question:
