The correct answer is: B. Identify all of the start codons in the model molecule.
One of two ways of finding gene locations is mapping the molecular locations (other is cytogenetic location, using chromosomes).
Finding the molecular location of the gene refers to finding the location of that gene in terms of base pairs. It means scan the DNA for start and stop codons. This can be complicated by the fact that there is some variation in start codons.
Finding the molecular location of one gene allows determination of exactly how far that gene is from other genes on the same chromosome.
Answer:
the tendency toward a relatively stable equilibrium between interdependent elements, especially as maintained by physiological processes.
Explanation:
The correct statement regarding the counter current exchange in fish gills are It is a very efficient way to capture oxygen from water, Water flows across the lamellae in the opposite direction of blood flow, Oxygen diffuses into the capillaries across the lamellae, because even as oxygen is depleted, it is still at higher concentration than in the Inflowing blood
Gills are used by fish to exchange gas. Gills have a lot of folds, which increases their surface area. They can extract oxygen at a rate that is three times faster than that of a human because the water flows past their gills in the opposite direction from the blood (this is known as countercurrent flow). Blood always flows close to water that has given up less oxygen due to the fact that it moves in the opposite direction of the water. In this manner, the blood is able to take in more and more oxygen as it flows. Even as the blood, which is about 80% oxygenated, travels to the lamella's conclusion, it passes water, which is at the lamella's beginning and is 90% oxygenated.Even as the blood, which is around 80% oxygen-saturated, approaches the lamella's end, it is passing water, which is 90–100% oxygen-saturated at the lamella's beginning. Because there is still a concentration gradient, the blood can continue to receive oxygen from the water even after it is highly saturated and has passed through most of the lamellae.
