Prokaryotic cells lack a defined nucleus, but have a region in the cell, termed the nucleoid, in which a single chromosomal, circular, double-stranded DNA molecule is located.
Answer:
There should be 10% thymine
Explanation:
DNA bases come in specific pairs. Guanine pairs up with cytosine and adenine pairs up with Thymine.
According to the problem the DNA sample was 40% cytosine and 40% guanine, so this is correct, there are equal amounts of cytosine and guanine. Now Thymine needs to have equal amounts as adenine, but adenine only has 10%.
If we match up the amount of adenine to thymine, we would have 15% adenine and 15% thymine, but that would excede 100%. So you need to match the thymine to adenine.
10% adenine + 10 % thymine + 40% cytosine + 40% guanine = 100%
Answer:
A) The gene flow between hatchery-reared and wild populations is leading to a decline in fitness of wild populations.
Explanation:
<u>we have relative fitness at its greatest in trouts whose parents are wild x wild. crossing the wild with hatchery reared causes a decrease in the fitness of the troutgene flow is the exchange of genes between two different breeds. the wild is a greatly diverse breed and it is highly adaptive. while the hatchery reared is less adaptive.when these two breed less fit alleles will then be transferred to the wild</u>
therefore option a answers the question
Answer:
A
Explanation:
You can replant and gain more crop from seeds. Therefore it is a renewable resource.
