In summary, a heritable characteristic that an animal or plant to have more offspring which survive to reproduce will tend to become more common in a population as a result of evolution by natural selection. prompt: explain why a characteristic which an animal to live longer will generally tend to become more common in the population as a result of evolution by natural selection.

Why do you suppose the structural polysaccharide cellulose does not contain branches? why do you suppose the structural polysaccharide cellulose does not contain branches? branches in the molecule would generate side chains that would almost certainly make it difficult to pack the cellulose molecules into globules, thereby decreasing the flexibility and strength of the globules. branches in the molecule would generate side chains that would almost certainly make it difficult to pack the cellulose molecules into microfibrils, thereby increasing the rigidity and strength of the microfibrils. branches in the molecule would generate side chains that would almost certainly make it difficult to pack the cellulose molecules into globules, thereby increasing the flexibility and strength of the globules. branches in the molecule would generate side chains that would almost certainly make it difficult to pack the cellulose molecules into microfibrils, thereby decreasing the rigidity and strength of the microfibrils.

Imagine that you push on a large rock. at what point does your effort change the rock’s mechanical energy?
