Answer:
Because of the difference in surface area to volume ratio
Explanation:
Surface are to volume ratio is the area of an object that is exposed to the external environment (surface area), compared to the amount within an object (volume).
Therefore an elephant has a lower surface area to volume ratio than a mouse.
The smaller an object is the greater its surface area to volume ratio.
Small animals have much more surface area per mass than large animals. With so much surface area, they lose heat very quickly. So, a mouse, with a lot of surface area per mass, must spend a lot more energy to stay warm than a large animal.
an agent, such as radiation or a chemical substance, which causes genetic mutation.
Answer:
10
Explanation:
Proteins are polymers of amino acids. 20 different amino acids are present in various combinations in different proteins. Humans are incapable of synthesizing some amino acids. These are called the essential amino acids as they must be provided in the diet.
Histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine are the nine amino acids that are not synthesized in the body of adult humans and therefore, are categorized as essential ones. Arginine is a non-essential amino acid for adult humans but is essential for adult humans. Therefore, for an infant, more than 9 amino acids are essential ones.
