Darker moths thrived in cities because they were able to blend into the trees better as the trees were covered in soot and coal from the factories nearby. The white moths are able to be spotted easier, this contributes to Natural selection by allowing the more successful moths (the darker moths) within the area to at least live long enough reproduce that strand of genes further. Hope this helped. If you have any more questions based on natural selection and/or biology please feel free to message me. Thanks,

A scientist used a radioactive isotope of nitrogen to label the nitrogenous bases of the DNA in bacterial cells. The labeled cel
Elza [17]

Answer:

<h2>D.  Radioactive nitrogen in the DNA of the bacterial cells is present in one strand of the DNA of all of the cells.</h2>

Explanation:

As given here,

The nitrogenous base of DNA is radio active labeled, and is grown in normal unlabeled medium.

As we know that DNA replication occurs in semi-conservative way, so after one round of replication, one parental strand would be radio active and other newly synthesized strand would be unlabeled.

So here, after one round of replication, one strand of all the newly synthesized DNA would be radio active and other strand would be normal.

Sorry but I am bad at biology
Nimfa-mama [501]

We have 600 grams of grass, which has 450 grams of water. This means that there are 600 - 450 = 150 grams of dry weight (aka dry grass without any water)

20% of the dry weight is the amount of protein the rabbit gets

20% of dry weight = 20% of 150 = (20/100)*150 = 0.20*150 = 30

<h3>Answer: The rabbit eats 30 grams of protein per day</h3>
