DNA is a chain of nucleotides bonded together.  On that chain there are particular portions of it that the sequence of the nucleotide codes for particular proteins; this is known as a gene.  In eukaryotric cells, DNA is coiled around proteins such as histones to form chromatids which when two join at the centre by a centromere to form a chromosome.

Stronger earthquakes closer to the surface and gas<br> explosions
Nana76 [90]

Answer:

Aftershocks are sometimes just as hazardous as the main quake itself. In fact, aftershocks may be so strong that they're stronger than the main quake. ... While foreshocks occur around the same time of the main quake, aftershocks may not occur until days or weeks later! The point at the Earth's surface directly above the focus is called the epicenter of the earthquake. At the epicenter, the strongest shaking occurs during an earthquake.

Hope this helps, have a great day/night, and stay safe!

Proteins help with acting as structural components in the body, speeding up chemical reactions, and transporting substances around the body. Proteins are made up of amino acids, which create enzymes. Enzymes are often affected by  environmental factors in the body such as concentration, temperature, and pH. 
Proteins are very important for DNA and RNA. (ribonucleic acid)

How does ADH work and what does it do?
olga2289 [7]

Answer:

The correct answer will be option-A.

Explanation:

ADH or anti-diuretic hormone is a chemical messenger produced by the hypothalamus in response to the water level in the blood, maintain blood pressure.

ADH is released in response to the osmolarity of the blood that is a low amount of water which is perceived by the osmorecpetors in neurons. The low level of water leads to the production of ADH from neurons which binds to the ADH receptors in the collecting tubules of the kidneys.

They allow insertion of aquaporins-2 in the membrane which allow re-absorption of the water to maintain the water level of the body.

Thus, option-A is the correct answer.
