Answer:

Part A: Proteins are made from amino acid monomers. There are 20 different types of amino acids which make up all the proteins of the body. The amino acids are made up of a carbon atom which is joined to an amino group, a carboxyl group and a variant group, known as R. Nucleic acids are made up of 5 carbon sugar, phosphate group and nitrogenous bases. Hence, nucleic acids are made up of nucleotides.

Part B: Protiens are important molecule which carry out various functions of the body. They are involved in regulation of various body process. Some proteins are involved in the transportation of various molecules. Other type of proteins are involved in various immune functions and hence protect the body. For example, antibodies are proteins which defend the body against pathogens.

Nucleic acids are involved in the storing and expressing of genetic information. They also direct the body for protein synthesis.

How are vascular and non-vascular plants different, and how do each of them work through osmosis?

Lilit [14]

Answer:

Explanation:

Vascular plants have tubelike structures that carry water, nutrients, and other substances throughout the plant. Nonvascular plants do not have these tubelike structures and use other ways to move water and substances.

Vascular plants are said to have a true stem, leaves, and roots due to the presence of vascular tissues. Non-vascular plants do not have true roots, stems, or leaves and the tissues present are the least specialized forms of tissue. Some examples of vascular plants include maize, mustard, rose, cycad, ferns, clubmosses, grasses. Some examples of non-vascular plants include moss, algae, liverwort, and hornwort.

How vascular plants work through osmosis

The xylem of vascular plants consists of dead cells placed end to end that form tunnels through which water and minerals move upward from the roots to the rest of the plant. Through the xylem vessels, water enters and leaves cells through osmosis.

How non vascular plants work through osmosis

Because non vascular plants do not have the xylem and phloem ystem, they absorb water right into their cells through their leaves when it rains or when dew falls. Internal cells get their water by passive osmosis. While, they use rhizoids to transport nutrients and minerals.

Jim does research in Antarctica. He frequently endures extremely low temperatures. Explain how his skin, muscles, and metabolism

kotegsom [21]

Answer:

Skin,muscles and metabolism play a significant role in maintaining his body temperature

Explanation:

Role of skin

In cold environment the blood vessels of the skin constrict to prevent the loss or liberation of heat from his(jim) body.

Role of muscles

The one of principle function of muscle is to store glycogen.The stored glycogen of jim"s muscle undergo glycogenolysis to generate heat inside his body.

Role of metabolism

In cold environment the rate of aerobic respiration and other catabolic reactions such as beta oxidation of fatty acid occur to generate energy in form of heat in his body.
