Answer:
Excretion is the process by which cells and organisms rid themselves of waste.
The arteries get "hard" and absorb less systolic force
Answer:
This question is incomplete, the complete question is: When a cell needs energy, I take in nutrients break them down, and supply energy to the cell. I can also convert stored energy in the cell to food. I am a?
The answer is MITOCHONDRION
Explanation:
All living organisms need energy at the cellular level to carry out their cellular activities. This energy is obtained by eating food. The energy in food is stored in the bonds of the sugar molecule that is contained in it.
However, via a process called CELLULAR RESPIRATION, the stored energy in food is broken down and used to synthesize a form of energy usable by the cell called ATP. This important process occurs in the organelle called MITOCHONDRION.
This phenomenon can be explained by Allen's rule. It says that the body proportions and shape may vary in different climates. The temperature decreases as the latitude increases, so in the northern region is much colder. Animals must preserve heat in such conditions. So, exposed surface areas of the body, such as the ears, feet, and tail, are usually minimized to minimize heat loss in the cold climate. <span>Therefore, northern species often have smaller ears, feet, and tail than the southern species. </span>
