A nuclease (also archaically known as nucleodepolymerase or polynucleotidase) is an enzyme capable of cleaving the phosphodiester bonds between nucleotides of nucleic acids. Nucleases variously effect single and double stranded breaks in their target molecules. In living organisms, they are essential machinery for many aspects of DNA repair. Defects in certain nucleases can cause genetic instability or immunodeficiency.[1] Nucleases are also extensively used in molecular cloning.[2]

Depiction of the restriction enzyme (endonuclease) HindIII cleaving a double-stranded DNA molecule at a valid restriction site (5'–A|AGCTT–3').

There are two primary classifications based on the locus of activity. Exonucleases digest nucleic acids from the ends. Endonucleases act on regions in the middle of target molecules. They are further subcategorized as deoxyribonucleases and ribonucleases. The former acts on DNA, the latter on RNA.[2]

A friend asks you how exocrine glands differ from endocrine glands. She knows that both form from invaginated epithelium. How do

klio [65]

Answer:

Exocrine glands secrete sweat and oil while endocrine glands secrete hormones.

Explanation:

As she knows the endocrine and exocrine glands in respect of their origin from skin, so our answer must be related to the skin so that she can understand easily. So our answer should be as follows -

Endocrine glands are those glands which secrete hormones directly to the blood stream but exocrine glands are those glands which secrete sweat and oils directly to the skin surface.
A duct is often present in exocrine glands but endocrine glands lack ducts.

The amount of water in each body compartment mainly is controlled by

Elis [28]

The<u> ion concentration</u> in water molecules controls the amount of water in a compartment

The concentration of ions in a body of water determines the rate of diffusion and osmosis that occurs in a body of water contained within a body compartment. which has a direct impact on the amount of water that is held in any water body compartment.

Hence we can conclude that the ion concentration in water molecules controls the amount of water in a compartment.

The large number of alveoli in lungs improve diffusion by ____.

nekit [7.7K]

Answer: a. Increasing the surface area for diffusion

Explanation:

When the air is inhaled through the nostrils, the air containing the oxygen the air diffuses inside the alveoli. The alveoli are the tiny sacs where air enters and exchange of gases takes place. From the alveoli the oxygen enters into the blood stream. The oxygen is utilized by the cells for respiration. The increase in network and number of the alveoli will increase the surface area for the diffusion of oxygen and hence, will speed up the respiration process.

A researcher is studying a population with a unique age structure. An age-structured histogram he has developed over the course

Rasek [7]

Answer:

The population first grows, stabilizes, and then declines.

Explanation:

A researcher is studying a population with a unique age structure. An age structured histogram he has developed over the course of several decades has undergone transformations in shape, from a pyramid shape to a roughly rectangular shape to an inverted pyramid shape (where the base is narrower than the top). The population first grows, stabilizes, and then declines.
