Can environmental factors influence the expression of traits?

Answers

Answer 1

Answer:

Environmental Factors Interact with Genes

Environmental factors often influence traits independently of genes. But not always. Sometimes the environment changes a gene—either its DNA sequence or its activity level. Either of these effects can change the proteins that are made from a gene, which in turn affects traits.

Answers

All of the following are essential amino acids except: b) Alanine.

What is Alanine?

Since alanine is a non-essential amino acid, the body can produce it on its own and does not need to be consumed in the diet. From other amino acids and metabolic processes the body may make alanine.

The amino acids indicated in alternatives a), c), and d), on the other hand, are essential amino acids which means that the body cannot produce them and that they must be received from diet. These amino acids are essential for the production of proteins as well as other physiological processes.

Therefore the correct option is b.
