Answer:
Soil pollution- Soil pollution is defined as the presence of toxic chemicals in soil
it could pose a threat to humans, etc...
caused by the presence of xenobiotic chemicals
(A xenobiotic is a chemical substance found within an organism that is not naturally produced or expected to be present within the organism.)
or other alteration in the natural soil environment. It is typically caused by industrial activity, agricultural chemicals or improper disposal of waste.
Air pollution- Air pollution is a mixture of solid particles and gases in the air.
Car emissions, chemicals from factories, dust, pollen and mold spores may be suspended as particles.
Explanation:
The lysosomes are responsible for that
The change in foot shape making the feet wider and longer than the hands and the curvature of the spine also adapted to it
<span>Some mutations don't have any noticeable effect on the phenotype of an organism. This can happen in many situations: perhaps the mutation occurs in a stretch of DNA with no function, or perhaps the mutation occurs in a protein-coding region, but ends up not affecting the amino acid sequence of the protein.</span>
I have provided the options below:
a. 150
b. 225
c. 300
d. 450
e. 75
Answer:
150
Explanation:
Hardy-Weinberg law states, the allelic frequencies of a gene that is, q and p follow the relationship p^2+q^2+2pq = 1, if the population is in equilibrium.
Therefore p^2+q^2+2pq = 1, can be used to calculate the percentage of the allelic frequencies i.e. p^2 and q^2
Allelic frequency = 0.75.
Therefore, the percentage of the allele in the population would be given by
0.75^2 = 0.5625 = 56%.
And the total number of individuals with this allele in the population:
number of individuals = 56×300÷100
= 168 or
150 nearest figure.
