The simplest form of life existing on earth is the prokaryotes. Prokaryotes have a single celled structure which does not contain an individual nucleus. Also it has no membrane bound organelles. There are several organelles which are not even present in prokaryotes as compared to a eukaryotic cell. They have a simple chromosome that is circular in shape

Prokaryotes include bacteria and archaes

Hey y'all I need help with this bio question: what are the pros and cons of different skin tones in different parts of the world
d1i1m1o1n [39]
Oh this one is so cool!

It basically all boils down to Vitamin D! We need this essential vitamin to help our body build hormones and regulate calcium. Our bodies make Vitamin D when we are exposed to the UV rays found in sunlight. But as we all know, too much sunlight isn’t good because these UV rays can harm us. Melanin (the chemical that our bodies produce to darken skin tone and hair color) provides protection from UV rays by absorbing them. However, this means that the more melanin that is produced by someone’s body results in less absorption of UV rays and a decrease in Vitamin D production. But for someone living around the equator or in the tropics that doesn’t matter because there’s lots of sun all the time. So for humans living in these areas where there’s lots of sunlight year round, it’s beneficial to have darker skin to protect from the harm of UV rays. People living in these areas still get plenty of Vitamin D though because of that year round sunshine.

Now what about those who’s skin has less melanin, such as those found in the higher latitudes? Well with less sunlight year round, their bodies had to adapt to be able to get enough Vitamin D. So less melanin is produced by the body in order to absorb the lesser amounts of UV rays to make Vitamin D. Lighter skin is, therefore, more beneficial the farther away you go from the tropics.

So essentially:
Pro of Darker Skin tones
-Protection from harmful UV rays

Con of Darker Skin tones
-Less absorption of UV rays and less production of Vitamin D

Pro of Lighter Skin tones
-Greater absorption of UV rays and more Vitamin D production

Con of Lighter Skin tones
-Less protection from harmful UV rays (resulting in sunburns and, in extreme cases, skin cancer)

This is of course the biology answer. The social impacts of different skin tones is a whole different story that you can ask in the history section.

Which of the following statements is not true of antibody staining? Which of the following statements is not true of antibod
Free_Kalibri [48]

Answer:

The statement that is not true for antibody staining is it can provide information about gene expression.

Explanation:

Antibody staining is important aspect of applied immunology. Antibody staining is done to determine a specific protein in a given sample.Antibody staining is done by using fluorescent dyes and also by using specific enzyme such as horse reddish peroxidase,alkaline phosphatase.

         Antibody staining can be visualized with either fluorescent or radioactive labels. Antibody staining can be performed by western blotting method.Multiple antibodies can be used to stain different proteins.Antibody staining requires the hybridization of the complementary base sequence of the antibody and also the target protein to which it binds.
