Construction of a new road system splits a population of a rare snail species into three sub- populations, J, K and L. Each of these populations is reproductively isolated.
The table shows the sizes of the three populations immediately after the building of the road
and again ten years later. DNA analysis was used to find:
p the relative frequency of the dominant allele of a gene
q the relative frequency of the recessive allele of this gene.
The three areas of habitat remained the same as each other over the ten year
immediately after road building
after 10 years
population p q size

Which statements are supported by this data?
Statement 1: Statement 2: Statement 3:
Natural selection is occurring in populations K and L.
The Founder Effect is strongest in population L.
The observed allele frequency changes result from genetic drift.

Examine the chemical formula shown here there are three total atoms two of which are hydrogen and one of which is oxygen and this chemical formula can be seen in the process of photosynthesis also.

What is photosynthesis?

The process of photosynthesis has been defined as the process in which green plants prepare their own food in the presence of sunlight and during this process heat energy has been converted into the chemical energy and this process has been taken place in the green plant only.

Photosynthesis has the process through which plant cells use carbon dioxide & water to create oxygen & energy rich organic compounds. They do so by converting sunlight ie light energy into chemical energy. This is possible due to presence of chlorophyll in them. Animals can't do so, as they dont have chlorophyll.

Therefore,Examine the chemical formula shown here there are three total atoms two of which are hydrogen and one of which is oxygen and this chemical formula can be seen in the process of photosynthesis also.
