Answer:
single gene traits are generally not significantly influenced by the environment, whereas complex traits have a significant environmental component
Explanation:
Single gene traits that are controlled by a locus, that is two alleles of a trait controls the expression of a character. Single gene traits are said to be involved in Mendelian inheritance. These traits are not all significantly influenced by environmental factors. On the other hand, complex traits, such as height in humans, which is controlled by 10 or more allelic pairs, have been found to be significantly influenced by environmental components like diet. This explains why the expression of height in human population is widely varied, and when each individual’s height of a population is plotted on a graph, we would see a normal distribution curve with a bell curved shape.
Answer:
polymer any of a class of natural or synthetic substance composed of very large molecules called macromolecules,that are multiple of simpler chemical units called monomers .polymers they make up many of the materials in living organisms example proteins , cellulose
1. Gases are exchanged inside the
lungs through the surfaces of
thousands of alveoli to allow the
diffusion of carbon dioxide and
<span>oxygen
2. </span>Wastes are removed through the excretory system after passing through
either the kidneys urine or the digestive tract feces
3.Blood is redirected after a change in blood pressure after birth. Blood
now flows through the pulmonary artery to the lungs to receive oxygen
4. The lungs alveoli, the intestines, the
pulmonary artery, and the excretory system

Answer:
There are four major classes of biological macromolecules (carbohydrates, lipids, proteins, and nucleic acids); each is an important cell component and performs a wide array of functions. Combined, these molecules make up the majority of a cell's dry mass (recall that water makes up the majority of its complete mass)
