Charles Darwin noticed that among the same species there were variations in traits based upon geographical location. These changes may have evolved from climate differences, predator/prey relationships and food sources. This particular experiment was intended to duplicate natural selection by demonstrating the concepts with artificial selection. The result was that over time, new traits could be bred for. Although there may be more than one correct answer here, the best answer is the first; desirable traits can be selected and bred in offspring.
It depends on which macromolecule you are referring to. As examples:
Protein monomers are amino acids.
DNA monomers are nucleotides.
Carbohydrate monomers are monosacharides.
Lipid monomers are fatty acids and glycerol.
The two main types of plants are vascular and non vascular
<span>1. What is an endotherm?
Endotherm is an animal that keeps their temperature constant in a certain range. Keeping temperature is important because most enzyme has an optimal working range. By keeping the temperature at optimal range for the enzyme, the organism can do metabolism more efficient.
2. how do sweating, fur, and feathers affect the body temperatures of endotherms?
The environments temperature should influence the temperature of an organism that lives within it. </span>Endotherms need to control their temperature, so they have some mechanism to increase/decrease the body temperature. or to insulate themselves from the environment.
Sweating help decreasing temperature makes the organism can withstand hot environment. Fur and feather will insulate the body, makes the organism more resistant to cold.<span>
