Answer:

Ozone

Explanation:

Ozone is considered a pollutant in the troposphere, but in the stratosphere it is essential to life on earth because it absorbs biologically harmful UV radiation. The mesosphere and the thermosphere are two additional atmospheric layers above the stratosphere.

What statement best summarizes the relationship between photosynthesis and cellular respiration? (2 points)
Dominik [7]
1) Photosynthesis uses sunlight energy to produce sugar. Sugar goes from one cell to another until it reaches the cells which don’t have access to sunlight (or they don’t get enough sunlight), so they can’t make any photosyntesis or they make very little photosyntesis. That’s how the leaves of a plant feed the roots of the same plant. When that cell receives the sugar, it makes cell respiration to convert it back to water and CO2 and release energy. When an animal eats a plant, animal cells also make this respiration process with the sugar.

The chemical equation is basically the opposite:

Photosyntesis: water + CO2 -> O2 + sugar

Respiration: sugar + O2 -> CO2 + water

 

2) The DNA duplication is semiconservative, which means each new double chain contains 1 original molecule and 1 newly synthesized molecule.

When DNA is duplicated, each one of the molecules (chains) acts as a template for one of the chains that are being synthesized. Wherever there is an A in the old molecule, the new molecule will have a T. G goes with C, C goes with G and T goes with A. The way this happens is related to the number of hydrogen bonds (C and G have 3, whereas A and T have 2) and the molecular size (A and G have 2 cycles, whereas T and C have 1 cycle – so it is always a big one with a small one, total = 3 cycles). You can compare it with a chocolate mold: if you want a chocolate to be heart-shaped, you have to get a mold which has a heart-shaped hole and put the warm chocolate inside. So the mold and the chocolate have the opposite shape – complementary shape. But in this case, once the duplication process ends, mold and new DNA stay together as a brand new couple, and the mold never goes back with the other mold.

Why is meoisis important for organisms?
lana [24]
Organisms make gametes through meiosis.

Meiosis is a process where a single cell divides twice to produce four cells containing half the original amount of genetic information. These cells are our sex cells – sperm in males, eggs in females.

spayn [35]

Genetic polymorphisms in diverse genes such as SLC6A2 and DRD2 may be associated with the outcome of behavioral/mental conditions including depression.

<h3>What are genetic polymorphisms?</h3>

Genetic polymorphisms refer to certain genetic variants associated with a phenotype in particular, for example, a neuropathological condition. Moreover, it has been shown that depression is a multifactorial mental disease caused by both genetic factors and environmental triggers.

In conclusion, genetic polymorphisms in diverse genes such as SLC6A2 and DRD2 may be associated with the outcome of behavioral/mental conditions including depression.
