Human skin color is a polygenic trait, which means that multiple gene loci (with different alleles) are involved in its expression. It has been shown that there more than 350 genetic loci involved in determining skin color. Because of that, there is the enormous number of possible genotypes for the skin color and as a result, the phenotypes vary from the darkest brown to the lightest hues. Different populations have different allele frequencies of genes for human skin color, and the combination of these allele variations brings about complex and continuous variation in skin coloration. Natural skin color can change due to exposure to sunlight (becomes darker) and that is the way it adapts to intense sunlight irradiation (protection against the UV exposure).

The resin why our brain changes throughout our life time as human beings, is simply because of age. Whatever you might learn, or adapt to it will all effect the brain. Everything you do is what your brain makes you do, and it changes with everything you do it all has a huge impact on your brain. Everything, its all about age and time. Hope this was helpful !!
Answer:
True
Explanation:
A general misconception is that insulin is only involved in energy and fat metabolism. When energy needs are high, insulin transports sugar from the blood into the muscle where it can be converted into energy. When energy needs are low, insulin facilitates the conversion of excess sugar into fat where it can be stored for future use.
What is often overlooked is the powerful effect of insulin on stimulating muscle protein growth and repair. An essential action of insulin is to increase the transport into muscle of amino acids, the building blocks of protein, where they can be used for rebuilding and repair. Insulin’s anabolic effects do not end there. Insulin also plays an important role in turning on one of the metabolic switches that control protein synthesis.
This action explains why combinations of carbohydrate and protein are far more effective in stimulating protein synthesis than protein alone. Two switches are responsible for turning on protein synthesis. One is activated by protein, specifically amino acid levels in the blood, and the second by insulin. Consuming carbohydrate (which raises insulin levels) and protein in your recovery drink gives you a dual benefit. In fact, research has shown that a carbohydrate protein drink is 38% more effective than a protein drink in stimulating muscle protein synthesis post exercise.
Another important effect of insulin is inhibition of protein breakdown. At any given time, muscle protein is in a state of flux – it is being synthesized and broken down. When more protein is synthesized than broken down, you have a net gain in lean body mass. After exercise, protein degradation is higher, primarily because during extended endurance activity up to 20% of the working muscle’s energy is derived from protein. That’s why consuming protein in your sports drink offers significant advantages. It reduces the amount of muscle protein used for energy. Higher breakdown rates of protein after exercise increases muscle soreness and slows the overall recovery process. By inhibiting protein breakdown, insulin mediates a faster recovery.
The bottom line – by taking advantage of how and when insulin works and how nutrition can affect insulin activity, endurance athletes can optimize muscle recovery and achieve significant improvements in endurance performance.
In contrast to vinyl, which is lightweight and can be affixed directly to the framing, stone and brick need support when used as external siding.
<h3>Why do people frame works of art?</h3>
The way we experience art can be greatly influenced by the frames. They can be crucial in safeguarding the artwork in addition to improving how it looks. Some frames may even increase the value of the art that is displayed inside them.
<h3>What Is a Frame?</h3>
Art that has been framed has been mounted inside of a picture frame, usually behind glass. Fine art, art prints, antique posters, photographs, or any other piece of artwork can be protected against UV rays, water, dust, and scratches by framing.
<h3>Describe framing.</h3>
The arrangement of visual components in an image or layout in relation to the primary subject is known as visual framing.

The kingdom of fungi is made up of variety of organisms, such as mushrooms, yeast, molds, etc. The organisms in this kingdom live by decomposing and absorbing the organic molecules on which they grow.
The major characteristics of the organisms in the fungi kingdom is that they possess hyphae, which they use for absorption of nutrients.
The organisms in the fungi kingdom are multi cellular eukaryortic and are incapable of producing their own food, that is, they are heterotrophs.
