<span>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.</span> <span> 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).</span>
Answer: by eating meat from animals...?
Explanation: Well lions do actually eat meat so whenever they eat meat I'm guessing they get whatever they need. I'm still learning so sorry if I am wrong.
Under the dissecting microscope I was able to view the surfaces of specimens such as a feather, insect, and leaf.
Under the compound microscope I was able to view a leaf, blood, and algae. I was able to observe the surface of the specimens in greater detail then I was able to view the surfaces under the dissecting microscope. For an example under the compound light microscope I was able to view the leaves surface which contained multiple lines that intertwined into each other and rectangular chambers of green dots. But under the dissecting microscope I was only able to view the surface of the leaf which consisted of thin white cracks in the leaf.
Under the scanning electron I was able to view the internal structure of the following specimens: a leaf, blood, and algae.
Under the transmission electron I was able to view a more in depth internal structure of the following specimens:a leaf, blood, and algae. I was able to observe the intern
al structures of the specimens in greater detail then I was able to view the internal structures under the scanning microscope. For an example under the TEM I was able to study the internal structure of a leaf which consisted of long thick and thin black and gray lines coated with black rectangles and tiny dots littering he perimeter of what looks to be the internal structure of the leaf. But with the SEM I was only able to view the first layer of the leaf's internal structure which consisted of mushroom like figures surrounded be compound and single molecules.
Sources emit greenhouse gases.
Global temperature rises.
Snow and ice.
Sea level rises.
Climate change is the critical alteration in the measures of
climate, such as temperature, rainfall, or wind lasting for an drawn-out
period. It can result from factors more
recently from human exercises through greenhouse gas emissions. The
"greenhouse effect" changes the composition of the atmosphere and traps
heat increasing the global average temperatures. Snow and ice, which helps
regulate the Earth's surface temperature, melts and fills reservoirs and other
bodies of water, causing a rise in sea level.
