The correct option is C.
Scanning electron microscope is a type of microscope that uses beams of electrons that are reflected to form images to scan the surfaces of mounted biological specimens. High resolution, three dimensional images can be obtained via the reflected beam of electrons. Thus, the electron scanning microscope is the perfect microscope for examining the contours on the surface of a bacterial cell.
The options attached to the above question are given below:
A) The boys at first were very polite about my medals and asked me what I had done to get them.
B) I showed them the papers which were written in very beautiful language of full of fratellanza and abnegazione but which really said with the adjectives removed that I had been given the medals because I was an American.
C) after that their manner change a little toward me although I was their friend against Outsiders
D) I was afraid but I was never really one of them after they had read the citation because it had been different with them and they had done very different things to get their medals.
E) I had been wounded it was true but we all knew being wounded after all was really an accident.
ANSWER
The correct option is D.
In the statement given in option D, it can be seen that the speaker was formerly a soldier, who had fought in a war and had been awarded a medal to that effect. But despite knowing about this meritorious service that he had rendered to his country and the award he was given, he was not really accepted as an inner person by the group of people that was refereed to in the statement. They did not think much of him.
Explanation: Sudden Increase Factors:
- Since there are no predators, there are no ways they could be eaten, with this case, it significantly increases the population.
- Since there are a lot of females, and some males, the males could find mates, and have some baby reindeer, which also increase the population.
Sudden Decrease Factors:
- One decreasing factor is starvation. With there being so many reindeers, all the food is going away quickly. After a few years after the growth spurt, most of them probably died because of there not being a lot of food.
- Another decreasing factor is Old Age. Since there are 21 females, they are older than the babies, and they couldn't have lived much longer, and probably died.
- Another factor; sickness. With there being starvation, their immune system is degrading, and meaning sicknesses could come, so maybe a huge sickness // disease came, and wiped out quite a bit of the population.

Answer:
B) Krebs cycle (citric acid cycle)
Explanation:
Glycolysis breaks glucose into two pyruvate molecules. Pyruvate is decarboxylated into acetyl CoA and the reaction occurs in the matrix of mitochondria. In the mitochondrial matrix, acetyl CoA enters Kreb's cycle and is broken down into CO2 and H2O. For one molecule of acetyl CoA, two molecules of CO2 are released as a by-product. Therefore, out of three carbon atoms of pyruvate, two are released as CO2 during Kreb's cycle.
Four single bonds, 2- two single and one double bond, 3- one single and one triple bond, 4- two double bonds.
