Answer:

The correct answer will be: are the largest of the four main biological                    macromolecules, consist of DNA and RNA and whether an organism is a bacterium, tree, mouse, or human.

Explanation:

Nucleic acids are the macromolecules which act as genetic material of organisms.Two types of nucleic acids-DNA and RNA act as genetic material.

The structure of these nucleic acids are long chains formed by the bonding of nucleotide units. These nucleotides are made up of 5-C sugar, phosphate and nitrogenous base which make up the long chains of molecule and forms one of the largest biological macromolecule.

The order of nitrogenous bases (adenine,guanine, cytosine, thymine) in the functional part of DNA also called genes decides the fate of cell as they code for proteins. The sequence of these bases in genes is highly conserved among organisms giving uniqueness to the organism but the variation in the sequence of DNA or nitrogenous bases leads to the formation of new organism or new species.

Thus, these options are the correct answer.

The large number of antibodies that can be produced in a single individual is a result of a single B cell: producing multiple un
wariber [46]

The answer is; producing a unique antibody from all other B cells by genomic rearrangement.


An isolated B cell produces monoclonal antibodies (also called Immunoglobulins). Different B cell types produce different types of antibodies (hence the serum of an animal has polyclonal antibodies). Memory B cells are developed when a particular infection is eradicated by the immune system. These B cells proliferate when the infection returns by producing the same antibodies that were effective against the foreign entity.

vampirchik [111]

Answer: salt

Freshwater is defined as having a low salt concentration, usually less than 1%.

Minerals can a. provide energy to the body. b. become part of the body's structural systems. c. be degraded by the body. d. be d
slamgirl [31]

Answer:

b. become part of the body's structural systems.

Explanation:

  • Minerals are the inorganic regulators needed for different functions inside the body.
  • Minerals donot provide energy but involved in generation of energ through their metabolic function. (Hence option A is excluded)
  • They provide a good medium for the protoplasmic activities (permeability of cell membrane and normal functioning of cell)
  • Maintaining bod fluid balance.
  • For structural units.
  • Cannot be degraded in the body neither can be destroyed while cooking ( Hence option c and d are excluded)
  • They become the part of the body's strctral systems (Hence option B is the right answer)

How do veins keep blood moving
GenaCL600 [577]

Answer:

The return of blood to the heart is assisted by the action of the skeletal- muscle pump. As muscles move, they squeeze the veins running through them. Veins contain a series of one-way valves, and they are squeezed, blood is pushed through the valves, which then close to prevent backflow.
