Answer:
E. 1/600
Explanation:
Hint:
The probability of fixation of a new neutral mutation is 1/(2N)
Given N as 300
= 1/(2×300)
=1/600
Therefore,
1/600 gives a sure fixation of one allele from the large population
The best answer is D
A freely suspended magnet will always point in the North - South direction in the absence of any other magnet. This suggests that the earth itself behaves as a magnet which causes a freely suspended magnet (or magnetic needle ) to point always in a particular direction namely North and South.
The south pole of the earth's magnet is in the geographic north because it attracts the north pole of the suspended magnet and vice versa. However it is important to note that the position of earth's magnetic poles are not well defined because they are spread over an area.
Answer - Humans can do anaerobic and aerobic for cellular respiration.
Reasoning - Just like when we do intensity excercise our body will go into anaerobic since we work hard with little shortage of O2 which in turn acts like Cellular respiration since it's also exhibiting CO2. Also aerobic is when we have O2 enough to relive from going into anaerobe.
Bacterial binary fission is similar in some ways to the mitosis that happens in humans and other eukaryotes. In both cases, chromosomes are copied and separated, and the cell divides its cytoplasm to form two new cells. However, the mechanics and sequence of the two processes are fairly different.
