This is beneficial and is actually an adaptation of humans to climates with larger amounts of sunshine. The darker color of skin helps prevent damage such as sun burn.
Answer:a) decreased chromatin condensation
Explanation:
During eukaryotic cell division a chromatin becomes obvious and it is simply a mass of genetic material made up of DNA and proteins which condenses to form chromosomes.
The chromatin primarily function in the compression the DNA into a unit so compacted that will be so tiny and can fit within the nucleus.
Chromatin condensation is driven by condensins and interactions between histones.
Condensins however, are large protein complexes whose central role in cell division is chromosome organization and segregation.
Chemical manipulation as stated above is decreases the rate of chromatin condensation.
Answer:
The outside only looks pigmented because of the color reflecting off it, but the inside is white and unpigmented because it is reflecting all the colors. Does this help?
Erosion is the process of eroding or being eroded by wind, water, or other natural agents. Erosion can dissolve rock, weakening it or turning it into tiny fragments. Deposition is the process by which sediments settles out of the water or wind that is carrying it, and is deposited in a new location. <span>Deposition transports previously eroded sediments, which, at the loss of enough kinetic energy in the fluid, is deposited, building up layers of sediment. </span>
