Answer:

<em>Microevolution</em>

Explanation:

In ecological studies, microevolution can be described as the changes which arise in the allele frequencies of a population over a short period of time. These changes arise due to conditions such as a mutation which might be beneficial, genetic drift, genetic flow etc. Microevolution is caused when allele for certain traits are more favoured by the changing environment.

For example, the allele frequencies of a population might change after they become pest resistant.

Crank

Answer: B

Explanation:

Photosynthesis uses CO2 and water to make oxygen and glucose.

6CO2 + 6H2O → C6H12O6 + 6O2 This is the chemical reaction that occurs. Products are on the right and we can see glucose and oxygen are formed.

During which phase does the cell grow larger and doubles all its organelles?

Aleksandr-060686 [28]

Mitosis...the organelles double in numbers in this stage. how?
the cell is in resting phase, preforming cell functions then the DNA replicates.
and after that, thats when the organelles double to prepare for division. :)

The recombination frequency between linked genes A and B is 40%, between B and C is 20%, between C and D is 10%, between C and A

Alja [10]

Answer:

ACDB (or BDCA)

Explanation:

The linked genes A and B have a greater frequency of recombination (40%) and therefore they are found furthest away on the chromosome. Conversely, the smaller distance is between D and B, which exhibit a lower frequency of recombination (10%), while C is localized at the same physical distance of both A and B (20%), so the physical map is ACDB.

Physical map:

A--------C-----D-----B
