Answer:the villi of the intestine
Explanation:like the cristae of the mitochondria which increase the surface area for the production of ATP,the villi of the intestine acts similarly.
In animals, digested food pass from the stomach to the intestine. In the intestine , enzymes acts on the food. Absorption of food takes place there and there are some structures that facilitates it. The walls of the intestine have numerous foldings , alongside the presence of finger like projection called villi. Microvilli are also presence from the cell walls of the intestine . These projections increase the surface area for the absorbing of food .they brush against food in the intestine and promotes absorption of nutrients.
Answer:
D) Frequency results from environmental stresses, not dominance.
Explanation:
The allele frequency refers to the amount of frequency of a particular allele in a small population whereas the dominance and recessive are the measure of the effects of the allele on the population which decides the trait of an organism.
The frequency and dominance cannot be correlated with each other as the frequency of the allele in a population is the result of the environmental stress which are random and by chances, whereas the effect of dominance is not random but is the result of the favoured trait for survival.
Thus, Option-D is correct.
The tiny blood vessels that are responsible or have the role
of transporting absorbed nutrients in our body is the capillaries. It is a network
in which connects the venules and the arterioles in order to transport and
connect nutrients for evenly distribution in the body.
the answer is mitochondria
