How does the ozone layer help maintain ground-level air equality?

Biology
1 answer:
VikaD [51]3 years ago
4 0

Answer:

The ozone layer absorbs a large portion of incoming UV radiation, which keeps ground-level ozone from forming. A higher percentage of UV radiation entering the troposphere would allow a greater amount of ozone to form in the troposphere. Ozone is a pollutant in the troposphere. By regulating the amount of UV radiation that enters the troposphere, the ozone layer also regulates the amount of ozone formation in the troposphere.

patriot [66]

Answer:

The Cre-lox system triggers recombination of the androgen receptor gene in muscle cells

Explanation:

The Cre-lox system is capable of producing site-specific recombination events in a given DNA region. This technique enables the spatial and temporal control of target gene expression. The Cre-lox system contains a recombinase enzyme (Cre recombinase) that allows the recombination of specific nucleotide sequences (LoxP sequences), being thus used to produce genetic modifications (i.e., insertions, deletions, translocations, inversions, etc.) at target loci where LoxP sequences were inserted.

Under what conditions will the body use significant amounts of protein for energy during exercise?a.Inadequate calorie intakeb.I
irga5000 [103]

Answer:

Hello!

The answer is b. inadequate calorie intake and inadequate carbohydrate storage

Explanation:

Our body requires energy to carry out daily activities and body functions. This energy is available to the body in three forms:

  1. carbohydrates
  2. fats
  3. proteins

Carbohydrates are the first and most readily available source of energy as starch and complex carbohydrates and sugars are immediately broken down into glucose which is available for body cells. Excess glucose is also stored as glycogen in the muscles. During exercise, carbohydrates, particularly, glucose are the first sources of energy for the body.

Fats provide the highest energy of all three (9 kilocalories compared to 4 of protein and carbohydrates). Fats are stored in the body in the form of adipose tissues or body fat. Any excess energy is readily stored by the body in the form of fats.

As proteins are not stored by the body, they are the last to be broken down during strenuous or prolonged exercise. Protein, particularly the skeletal muscle is the last to be used for energy in case of low calorie intake and inadequate carbohydrate stores.
