Answer:

Students who take a PE class and who will be eating sugary snacks before PE.

Explanation:

The control variable (or control group) is an experimental element which is constant or unchanged throughout the course of the experiment.

The option "students who take PE class and who will be eating sugary snacks before PE" will remain unchanged and constant because the whole point of the experiment is to see the effects on students performance in PE after eating sugary snacks.

Hope this helps :)

Humans only have a few eye colors and only four ABO-based blood types. How can DNA tests definitively identify individuals when
ehidna [41]
The correct answer is that variable number repeats are used in DNA tests; they have hundreds of possible lengths. Eye color is determined by variations in a person's genes. Most of the genes associated with eye color are involved in the production, transport, or storage of a pigment called, melanin. Eye color is directly related to the amount and quality of melanin in the front layers of the iris.

Which of the following types of DNA damage cannot be repaired by base excision repair?
Elodia [21]

Answer:

c. Thymine dimer

Explanation:

Thymine dimer

Thymine dimer ( also called the DNA damage ) that is repaired by the nucleotide excision repair which involves the breakage of the phosphodiester bond on the side of the damage , and results in the excision of an oligolnueotide of 10-12 nucleotides in length .

But the base excision repair involves the removal of the damaged base , removal of short polynuceotide and resynthesis of this area with DNA polymerase .
