Andre45 [30]

Answer:

It could lead to several later problems in the cell.

Explanation:

Removing a piece of DNA could severely affect the cell but it could also cause nothing. Depending on the part that is damaged, it could codify for a vital protein but it could also be an intron, which are pieces of DNA that don't codify for any protein. This has been recently researched and even though there are introns that could cause some serious trouble, most of them are an unknown matter to nowadays scientists. Anyway, a wrongly repaired sequence could end in a mutation that can potentially damage the cell and therefore the organism.

Answer:

Null hypothesis: the behavior of mosquito larvae doesn't change in the presence/absence of predators added to the tanks in Treatments 2 and 3.

Explanation:

In statistics, the null hypothesis states that there are no differences between the two variables tested in the experiment, while the alternative hypothesis uses the experimental data in order to reject the null hypothesis. In this case, the alternative hypothesis will use the data from treatments 2 and 3 to confirm that predators can modify the behavior of mosquito larvae.

What enzymes catalyzes the elongation of dna?
svp [43]
The enzyme that catalyzes the elongation of DNA is called DNA polymerase. DNA polymerase synthesizes DNA molecules from deoxyribonucleotides which are the building blocks of DNA. This enzyme is very important to DNA elongation and it works by creating two pairs of  identical DNA strands from from a single strand of the parent DNA.

Why were the high concentrations of DDT in the birds bodies?
ASHA 777 [7]

Answer:

because chlorinated hydrocarbons accumulate in fatty tissues, when a ton of contaminated fishes is turned into 200 pounds of seabirds, most of the DDT from the numerous fishes ends up in relatively few birds. As a result, the birds have a higher level of contamination per pound than the fishes.

stay safe! :3
