Answer:
If I can deternine the field-of-view diameter, it makes it easy for me to determine the size of an organism in the field of view.
Explanation:
The advantages of knowing the diameter of the field of view at a given magnification are that I can have a mental picture of the approximate size of how large the specimens are when I can’t certainly determine them with a simple ruler and the metric system. It also enriches me with a good concept of vital ideas of the size of my samples and the size of what’s the organism.
A)codominance that's when you see two colors, spotted or striped.
Antarctic fish species requires an adaptation to cold environment. Living at cold temperature environment would demand certain biological responses such as cutaneous respiration, enlarged blood vessels, and producing greater amounts of fat. Most of these fat are composed of higher phospolipid levels which are primarily due to phosphatidylethanolamine. This phospolipid is responsible for destabilizing cell membranes and make it more fluid thereby allowing unrestricted blood flow. The fatty acid composition of the membrane lipid is important for membrane fluidity, this is mainly attributed to unsaturated fatty acids which are responsible for decreasing the order of membrane lipids thereby decreasing viscosity. At extremely low temperatures, organisms with low concentration of unsaturated fatty acids would freeze cell membranes. That's why antarctic fishes have higher levels of unsaturated fatty acids.
Xenografts are tissue grafts harvested from a different animal species.
Answer: A) The resident populations are more likely affected by these threats because of their proximity to shore.
Explanation:
All of these threats are higher in coastal regions.
As contaminants usually reach the ocean through rivers or because of coastal cities, the highest degree of pollution is there. All chemicals will accumulate in this region first, before they disperse into the offshore region. This is also caused by the fact that the coastal waters have a lower volume and surface area than the offshore which results in a higher degree of contamination.
