There must be a balance between the flow of energy into the atmosphere and the flow of energy out of the atmosphere and back to space.<span>After being warmed by incoming solar radiation throughout the day, the Earth emits infrared radiation, which is trapped near the Earth’s surface by carbon dioxide.This radiation is called thermal radiation.</span>
Answer:
The correct answer is - option c.
Explanation:
Benedict test is used to test the presence of reducing sugar in a sample. If the benedict solution turns in red or orange color it means there is a presence of glucose as it is a reducing sugar. So, this test result shows that there no reducing sugar in the sample as it is blue.
Lugol test is the test to see if the sample has starch in it or no by turning in to blue color, in this result, it is orange in color which suggests that there is no starch available.
A Biuret solution is used to test for the availability of protein in a particular sample, purple or pink color is the representation of the presence of protein. There is no protein as per result
Sudan red test is used to test the presence of TGA, lipids, or lipoproteins in a sample by reacting with it and turn in to red color. The absence of the lipids shows no change as it is shown in this test.
Thus, the correct answer among these options is - option C.
Answer:
In the mid-1800s, over-hunting of Northern Elephant Seals reduced their population size to fewer than 40 individuals. However, the population has since rebounded to over 100,000 animals. The population went through a _<u>bottle neck event (genetic drift)</u>_, which makes it more susceptible to _<u>developing a genetic disease</u>_.
Explanation:
Genetic drift is the random change that occurs in the allelic frequency of a population through generations. The magnitude of this change is inversely related to the size of the original population. These changes produced by genetic drift accumulate in time. Eventually, some alleles get lost, while some others might set. Genetic drift affects a population and reduces its size dramatically due to a disaster or pressure-bottleneck effect- or because of a population split -founder effect-
. The bottleneck effect most likely affects smaller populations.
In the exposed example, extensive hunting acted as a pressure that reduced the number of Northern elephant seals to fewer than 100. This population experienced one or many generations of small size since these animals were affected by hunting. As the survivors did not have the whole genetic pool of the original population, the <em>population size might have recovered to a current population size of 100,000 individuals</em><em>,</em><em> but the genetic pool might have not</em><em>.</em> When the small population increases in size, it will have a genetically different composition from the original one. In these situations,<em> there is a reduced genetic variability, with a possibility of developing a peculiar allelic component</em>. If the <em>survivors in the population carried or developed a mutation, probably this mutation passed from generation to generation</em>. It will involve <em>more individuals each time and</em><em> increase the probability of developing a genetic disease.</em>
