substance in which the monomer is a nucleotide _______
A - Carbohydrates
B - Nucleic Acids
C - Proteins
D - Fats
Nucleic acid is a substance in which the monomer is a nucleotide. Therefore, option B is correct.
What are nucleic acids?Biopolymers and macromolecules called nucleic acids are important for all known forms of life. They are constructed of monomers called nucleotides, which are composed of a nitrogenous base (adenine, guanine, thymine, uracil, and cytosine), a phosphate group, and a 5-carbon sugar.
The components that make up an individual's genetic code are nucleic acids. Deoxyribonucleic acid (DNA) and ribonucleic acid are the principal two examples of nucleic acids (RNA). They have an important role in heredity and protein synthesis.
Thus, A nucleotide serves as the monomer of a material known as nucleic acid. Therefore, option B is correct.

3. What is the scientific term for a group of interacting individuals of the same type, living in the same area at the same time?
Answer: The scientific name is called POPULATION.
Explanation:
In basic ecological studies, POPULATION is defined as a group of interacting individual of the same type or species, living in the same area or habitat and at the same time.
Furthermore, to study a population of organisms, the different characteristics seen include:
--> Population size: This is important as it affects the survival of a given species in a habitat. A small population may be easily wiped out by events such a fire but a large population stands a better chance of survival.
--> Population frequency: This is simply how often the species occurs at different sites in a habitat.
--> Population density: this is the average number of individuals of a species per unit area of the habitat.
--> Percentage cover: This is the area of ground occupied by a given species in its habitat.
--> Distribution: This is the way in which individuals of a particular population are arranged in a habitat. They may be clumped, evenly spaced or randomly spaced.

Whích statement is best supported by the diagram?
А.
Species T and Species U are related to species X
B. Species X evolved later than Species U but before Species s.
С.
Species T is the ancestor of Species S.
D
Species U and V evolved from Species S.
Answer:
4
Explanation:
The statement that is best supported by the image is that species T and species U are related to species X.
What is evolution?Is the gradual development of new forms of organisms from their ancestral forms.
In the image, X is the ancestor of T, U, V, and S. Thus T, U, V, and S are related by common ancestry.
Thus, it is correct to say that T and U are related to species X.
However, it is incorrect to say that X evolved later or species U and V evolved from S.

Hello. Your question is incomplete. The complete question asks for the correct answer to be found based on Catalase is an essential enzyme in living beings since all cells need it.
Answer:
B. Cells only function within a specific temperature range because enzymes only function within a specific temperature range.
Explanation:
Catalase needs to be present in all cells of the living organism because it is responsible for the decomposition of hydrogen peroxide that cannot stay inside cells for long periods of time. Following this type of reasoning, we can say that it is necessary to maintain a constant temperature for the enzymes of an organism to function well because all enzymes have a specific temperature range, even catalase.
The specific temperature range determines that the enzymes will only work within that range. Therefore, an environment where the temperature is below or above that specific range, can prevent the enzyme from functioning and even cause irreversible damage to the enzyme.
beak shape, camouflage, and webbed feet are all examples of which type of adaptation
Answer:
beak shape: used to help an animal eat food like tearing apart food or either cracking nuts.
Camouflage: the color or shape of an animals body helps it blend into its envierment.
weebbed feet: help animal's propel themselves through the water with ease. This can help the animal swim faster to
catch prey or escape a predator. Also, if an animal has to swim long distances,
webbed feet can help it save energy so it can swim farther.

describe two ways to transfer electric charge
.Answer: conduction or polarization
Answer:
conduction, friction
Explanation:
Friciton: When insulating materials rub against each other, they may become electrically charged . Electrons , which are negatively charged, may be 'rubbed off' one material and on to the other. The material that gains electrons becomes negatively charged.
Conduction: During charging by conduction, both objects acquire the same type of charge. If a negative object is used to charge a neutral object, then both objects become charged negatively. In order for the neutral sphere to become negative, it must gain electrons from the negatively charged rod.

how are adaptation and variation similar?
Answer:
Adaptations are physical or behavioral traits that make an organism better suited to its environment. Heritable variation comes from random mutations. Random mutations are the initial cause of new heritable traits. For example, a rabbit can't choose to have a different fur color.
