Which two macromolecules contain nitrogen?

2 answers:

5 0

There are four classes of macromolecules (polysaccharides or carbohydrates, triglycerides or lipids, polypeptides or proteins, and nucleic acids such as DNA & RNA). Carbohydrates and lipids are made of only carbon, hydrogen, and oxygen (CHO). Proteins are made of carbon, hydrogen, oxygen, and nitrogen (CHON).

Answer:

Proteins and nucleic acids

Explanation:

Proteins are the polymers of amino acids. Each amino acid has one central carbon atom to which four functional groups are attached: amino group, carboxyl group, hydrogen atom and side chain.

Nucleic acids (DNA and RNA) are polymers of nucleotides each of which consists of pentose sugar, phosphate molecule and one nitrogenous base (adenine, guanine, cytosine, uracil and thymine).

Hence, amino acids and nitrogenous bases of proteins and nucleic acids contain nitrogen.

4). Which process can result in decreased biomass for a plant: cellular respiration or photosynthesis? Where does the mass/matte

zhuklara [117]

Cellular respiration results in decreased biomass for a plant. <span>In cellular respiration glucose and oxygen yield water and carbon dioxide. So, carbon dioxide is released in the into the air instead of forming organic molecules which could increase the biomass.</span>

The diagram below represents a change in guard cells that open and close pores in a plant) This Change directly helps to A. incr

AveGali [126]

The correct answer is option C, that is, regulate water loss.

Guard cells refer to the cells enclosing each stomata. They assist in monitoring the rate of transpiration by closing and opening the stomata. The guard cells possess the tendency to monitor the closing and opening of stomata by changing shape. The shape of the guard cells modifies on the basis of the concentration of potassium ions and water found in the cells themselves.

The stomatal pores get closed when carbon dioxide is no longer needed for the process of photosynthesis. The guard cells swell when movement of water takes place inside these pores, and thus, the opening of stomatal pores occurs, and as water moves out, the guard cell closes. Thus, guard cells play an essential role in regulating water loss.
