The image related to that question is attached below.
In the figure, we can see that on the left side, sea otters are very influential in the population of sea creatures, if the killer whales are not in the environment. That's because sea otters are strong predators of sea urchins. However, sea urchins are not as influential in the size of the seaweed population, providing little effect on that population. This is because sea otters control the population of sea urchins through predation. Thus, if more sea urchins are consumed by sea otters, the sea urchin population becomes small and consequently the consumption of algae (by sea urchins) is small.
On the right side of the figure, killer whales are great predators of sea otters and establish a strong predatorism, being very influential in the population of sea otters. This predatorism causes the otter population to decrease and stay in controlled and limited sizes. In this case, with few sea otters in the environment, their predatorism in relation to sea urchins is less, allowing the sea urchin population to grow and to consume more seaweed, providing a strong impact on the seaweed population.
A)
<span><u>proteins</u>
</span><span>Cell membranes contain membrane proteins that allows all the interaction that occurs within the cell. It makes the cell membrane selectively permeable because of its characteristics as being fluid or its fluidity which means to say that they can move freely within the lipid bilayer. The membrane proteins can also be stored in the lipid bilayer together with the enzymes. It cannot be denied that membrane proteins have a lot of functions based on its type. They can be integral proteins, peripheral proteins and lipid bound proteins. </span>
Proteins are unbranched polymers constructed from 22 standard α-amino acids.
The protein show four levels of structural organisation; the primary structure, secondary structure, tertiary structure and quaternary structure.
The structure of proteins are stabilized by peptide bonds between the amino acid and hydrogen bond between the peptide chainds.
The primary structure of a protein is determined by the sequence of amino acids, but secondary and tertiary structures of protein define their natural or native conformation.
The solubility of protein varies according to the pH, ionic strength, nature of solvent, temperature etc.
Proteins can be classified as simple proteins or conjugated proteins on the basis of their composition.
The proteins can also be classified as fibrous proteins or globular proteins on the basis of their shape.
Proteins play a major part in body structure and function as most of the molecules like antibodies, immunoglobulins, hemoglobin, myoglobin ,most of the enzymes are proteins.
So proteins are also called building blocks of the body.
Answer: dietary fiber
Explanation:
The dietary fibers can be defined as those nutrients in the diet which cannot be digested by the gastrointestinal enzymes and the minerals from them are not absorbed by the body. These keep the bowel full after food intake for long. These prevent disease like diabetes as reduces the need for consumption of more food, heart disease and constipation. The fruits, vegetable, legumes, fibers are the sources of dietary fibers.
Answer:
Humans crossbreeding animals and picking animals with specific traits.
