Answer:
210
Explanation:
Frequency of dominant allele is represented by "p"
and frequency of recessive allele is represented by "q"
Given
Thus,
As per Hardy Weinberg's second equation of equilibrium -
Substituting the given values in above equation, we get -
So the total number of heterozygous individual is equal to
Answer:
c. the plant root growing down into the soil
Explanation:
The plant root going down deep into the soil is an example of positive gravitropism. Gravity pulls everything towards the center of earth i.e. downwards and roots follow the direction of gravity automatically by growing downward towards soil that is why it is known as positive gravitropism. In short we can say that root favors the direction of gravity.
Shoot on the other hand show negative geotropism/gravitropism i.e. it grows towards the opposite direction of gravity. Shoot grow towards upside direction i.e. away from the surface towards sky.
You need carbon dioxide and oxygen because you need oxygen to breath and plants depend on carbon dioxide without it we would have plants and without plants we wouldn’t have food.
Most coelomates possess a "A. Circulatory system" because the main feature of these animals is that they posses a digestive tract, which requires a certain amount of circulation.
