Answer:
The frequency of both homozygous and heterozygous dominant species will start reducing and the frequency of homozygous recessive species will start increasing
Explanation:
Given-
Initial frequency of recessive allele is ![0.3](https://tex.z-dn.net/?f=0.3)
Since there is no migration and no selection the population follows Hardy's Weinberg's equilibrium.
Thus , the frequency of dominant allele as per Hardy Weinberg's equation would be -
![1-0.3\\=0.7](https://tex.z-dn.net/?f=1-0.3%5C%5C%3D0.7)
Humans enter this ecosystem and selectively hunt individuals showing the dominant trait. This means that they would be killing both homozygous and heterozygous dominant species.
Therefore, the frequency of both homozygous and heterozygous dominant species will start reducing and the frequency of homozygous recessive species will start increasing.
Answer:
Show the picture better for people to see
Explanation:
The picture doesn't mention mating or nesting - there is not a single mention of those. Therefore we cannot use answers 2) and 4), since we know nothing about them.
The same actually holds for 3) - while there is a mention of the beaks and you can infer the beak size, there is no connection between the beak size and mating activity.
so the correct answer is 1) -the type of beak is matched with the food.
The nucleus of the cell divides
Answer: Option D) 8 segments, with the 2 original strands on different segments
Explanation:
During polymerase chain reaction, a double stranded DNA (dsDNA) is selectively and repeatedly copied in the PCR machine.
In the first round, the single piece of double stranded DNA (dsDNA) unwinds in two seperate strands, before complementary nucleotides are synthesized to establish double helix.
In the second round, the two dsDNA yields 4 segments before complementary nucleotides are synthesized to establish double helix.
In the third round, the four dsDNA yields 8 segments before complementary nucleotides are synthesized to establish double helix.
Thus, after 3 rounds, the two original strands are on the 8 different segments of copied DNA.
