How do animals obtain the nitrogen they use to make proteins and nucleic acids? A. by consuming plants or other animals

B. by absorbing ammonia from bacteria growing in the roots of plants

C. by breathing the nitrogen present in the atmosphere

D. by absorbing nitrogen found in the soil

Answers

The correct statement that explains how animals obtain the nitrogen they use to make proteins and nucleic acids is:

by consuming plants or other animals.

What is the nitrogen cycle?

It is the biological process of plants, animals, and microorganisms and abiotic light, soil characteristics, among others, is based on the supply of nitrogen in living beings.

Characteristics of the nitrogen cycle

Biological fixation is achieved through symbiotic bacteria found in plants, in addition to absorbing nitrogen produced from the soil.

Animals obtain the nitrogen they need by feeding on plants or animals that contain nitrogen, to produce amino acids, proteins, nucleic acids and DNA.

Therefore, we can conclude that Nitrogen enters the food chain through the nitrogen cycle when plants and vegetables remove it from the soil; then it passes to herbivorous and carnivorous animals.

I think it would be A. Because plants have bacteria on their roots that take the free nitrogen in the air from the soil and turn it into usable nitrogen. Animals could get usable nitrogen from eating plants since they have bacteria that make it. Then if an animal eats an animal that ate the plant, then it could get that nitrogen. But i am not completely sure though. I just learned this recently. I hope this helped :)

The allele for round seeds is represented by R. Suppose that a pea inherited two recessive alleles for wrinkled seeds. How would you write the symbols for its alleles?

Answers

The allele for round seeds is represented by R. Suppose that a pea inherited two recessive alleles for wrinkled seeds. For wrinkled seeds, it would be rr.

What is the possibility of round seeds?

In pea plants the allele for round seeds (R) is dominant and the allele for wrinkled seeds (r) is recessive, Under the following conditions would we observe wrinkled seeds in a pea plant: When the plant inherits a recessive allele from both parents.

In pea plants the allele for round seeds (R) is dominant and the allele for wrinkled seeds (r) is recessive.

The plant with round seeds would have genotype RR.

The plant with genotype rr would have wrinkled seeds.

As we know that the recessive allele is only expressed when there is no dominant allele present so,

RR is dominant as both alleles are dominant

Rr is a heterozygous condition where one dominant allele comes from one parent and one recessive allele comes from another parent.

rr is possible which is wrinkled seed shape, only if each parent plant contributes one recessive allele.

Therefore, The allele for round seeds is represented by R. Suppose that a pea inherited two recessive alleles for wrinkled seeds. For wrinkled seeds, it would be rr.
