The evolution of human bipedalism which began in primates about four million years ago or as early as seven million years ago with sahelanthropus has led to morphological alterations to the human skeleton including changes to the arrangement and size of the bones of the foot, hip size and shape, knee size, leg length, and the shape and orientation of the vertebral column. The evolutionary factors that produced these changes have been the subject of several theories.

A dog eats a pound of dog food. What happens to the energy and chemical nutrients in the food over the next several days?
Black_prince [1.1K]

Answer:

The energy is mostly released as heat through the dog's activities; the nutrients either become part of the dog's body or are released to the ecosystem as wastes like urine, feces, and exhaled gases.

Explanation:

  • The food that is consumed by an organism is digested and the nutrients obtained from the food are partly absorbed by the digestive system and assimilated and stored into the body and the nutrients that are not absorbed are released in the form of feces.
  • The chemical energy obtained from the food is released in the form of heat through the activities that are done by the dog.

Why is diffusion important to biology?
myrzilka [38]
Diffusion is important to cells because it allows them to gain the useful substances they require to obtain energy and grow, and lets them get rid of waste products. I know this isn’t a straight answer but hopefully it helps.
