It's the cleanest water and it has all kinds of fishes and animals.
The answer is <span>The diploid chromosome number represents two sets of chromosomes, one from each parent, so it is always an even number.
Mentioned organisms are diploid (2n) and they have 2 sets of chromosomes in their somatic cells. However, their gametes (egg cells and sperms) are haploid (n) and have only 1 set of chromosomes.
After fertilization, a haploid egg cell from a mother and a haploid sperm from a father fuse and form diploid zygote:
n + n = 2n
Nevermind if n is odd or even number, 2n will always be even.</span>
Answer:
A)Tetrapods were no longer tied to the water for reproduction. B) Tetrapods could now function with just lungs.
They can study the number and organization of operons by reading the genome sequence.
Answer:
The answer is C.
Explanation:
The example process given in the question is describing the creating of a cDNA Library. cDNA or Complimentary DNA is copy of the DNA that is taken from a messenger RNA (mRNA), which is what is done with the reverse transcriptase. And the process described as cloning the resulting DNA into plasmids is the part where the library is created. The resulting DNA is put into host organisms and stored there for further investigation or use.
I hope this answer helps.
