<h3><u>Answer;</u></h3>
D) Mutations lead to new genes, which may have an advantage over the old forms, causing the species to evolve.
<h3><u>Explanation;</u></h3>
- <em><u>Mutations are sudden, random changes that occur spontaneously in the genetic make up of an organism.</u></em> Mutation are caused by various factors which includes errors in meiosis, and other factors such as chemical mutagens.
- <em><u>Mutations may be beneficial and may play an important role in evolution as they are raw material of genetic variation</u></em>. <em><u>Mutations may lead to genetic variations in the genetic make up of an organism . Therefore mutations are important to mutation since they create new DNA sequences for a given gene and thus resulting to new alleles.</u></em>
Answer:
Migratory birds play a critical role in the ecosystem, pollinating plants, dispersing seeds, and consuming insects and small mammals. ... Migration conditions appear to impact both annual survival and the timing of breeding, which in turn strongly predicts annual productivity within this population of migratory birds..
Explanation:
The correct answer is tick on a dog.
The parasitic relationship can be defined as the relation in which one organism feeds on the other organism for their nutritional purpose. It can also harm the other organism by any means. Here, tick on the dog is dependent on the dog for its nutritional requirement. This is an example of parasitic relationship between dog and tick.
Answer:
The correct answer is option d. "begins the production of a new glycogen molecule with the reactions of glycogenin".
Explanation:
As the name implies, glycogenesis is the process at which glycogen is synthesized. This process takes place by binding and addition of multiple glucose molecules. Glycogenesis begins the production of a new glycogen molecule with the reactions of glycogenin, an enzyme that acts as a primer and catalyzes the polymerization of the first few glucose molecules.
