Answer:
B
Explanation:
Helicase is the enzyme that unwinds the DNA by breaking hydrogen bonds between the two strands. It forms the so called replication fork.
No it’s not alive it just has adhesion as a property. It doesn’t have cells that make it living, and it doesn’t make or eat food to survive. And the force from the waves make it roll up on the beach, not because it’s alive.
Answer:
B. Theory
Explanation:
A theory can be changed as new information is discovered.
Plants use photosynthesis to get there energy from the sun. Chlorophyll is what’s inside of the plant that turns energy into useable carbon dioxide and water.
The frequency of allele is illustrated as the ratio of that specific allele in the population. As one knows that as the humans are diploid, so the total number of alleles is double of the total number of people in the population.
In order to determne the allele frequencies for A and B, there is a need to know that the persons with type A blood are homozygous AA, the persons with type AB blood are heterozygous AB, and the persons with type B blood are homozygous BB.
The frequency of A is:
2*(number of AA) + (number of AB) divided by 2 * (total number of individuals)
Therefore,
{2 * (200) + (75)} / 2 (200 +75 +25)
This comes out to be 475/600 = 0.792. Thus, p = 0.792.
Since, q is 1 - p
Then, q = 1 - 0.792 i.e 0.208.
