PATHOLOGY

Detailed explanation-1: -Environmental factors influence traits in plants and animals. These traits include things like weight, height, size, and color. If a child does not get proper nutrition, their height may be stunted as an adult.

Detailed explanation-2: -Behavior, environment, and genetic factors all have a role in causing people to be overweight and obese.

Detailed explanation-3: -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.

Detailed explanation-4: -DNA determines a person’s height. However, environmental factors, such as nutrition and exercise, can affect growth during development. As children get older, they need good nutrition and plenty of exercise to help their bodies make the hormones they need to grow.
