A geneticist is trying to recreate a strand of DNA from a crime scene investigation. The strand of DNA recovered from the scene

was 1800 bases long. The geneticist has determined that the strand contained 425 thymine
nucleotides. Based on this information, identify the number of cytosine nucleotides

Answer:

475

Explanation:

The strand is only made up of Adenine, Thymine, Cytosine and Guanine. There will be the same number of Adenine as there are Thymine and the same number of Cytosine as there are Guanine.

We know there are 425 Thymine. This means there are also 425 Adenine. Therefore, you would subtract 850 (425x2) from 1800 to find the amount of Cytosine and Guanine left, which is 950.

Out of the 950, half will be Cytosine and half Guanine. 950/2 is 475.

Scientists are interested in determining if selenium, from a nearby mine, magnifies in the tissues of fish living in a lake. Whi
kykrilka [37]

Answer:

The answer is A.

Explanation:

To test if the selenium from the mine has an effect on the fish living in the lake which i assume is close to the mine, testing the tissue of the fish from that lake and comparing it to the selenium levels of the fish from a nearby lake would be a testable hypothesis because there is a comparable aspect and there should be a difference in the numbers between the fish from the two lakes because of their distance to the mine.

I hope this answer helps.

Sources of oxygen and how the fish in water gets oxygen<br>​
WITCHER [35]

This process requires large volumes of water to pass through absorption surfaces to get enough oxygen into their bodies using their mouths and gills. These body parts work like a pump to keep water moving over the gas absorption surfaces of the gills.
