Answer: C
Explanation: Smaller single-celled organisms have a high surface area to volume ratio, which allows them to rely on oxygen and material diffusing into the cell (and wastes diffusing out) in order to survive. The higher the surface area to volume ratio they have, the more effective this process can be.
Answer:
so here correct option is A. 5
Explanation:
solution
as number of population groups live in a definite area is called diversity
so here in 1 there is only 2 groups of population
and in 2 there is 3 types of population groups
and in 3 there is 2 type of population groups
and in 4 there is 4 type population group
but they are not not evenly abundant and population of 1 group that is much less
so it might be a foreign population group
so here in 5 there is 4 type of population group which means it has higher diversity compare to other
so here correct option is A. 5
Answer:
All of the above
Explanation:
In letter A, B, and C; in different physical situation the molecule of water behave and put in charge with its peculiar polarity. Remember that is part its quite simple and molecular structure.
Water is "dipolar", because there is an uneven distribution of electron density. Water has a partial negative charge (Delta-) near the oxygen atom due the unshared pairs of electrons, and partial positive charges (Delta-) near the hydrogen atoms.
The dark brown color of a penny is most likely oxidation, which occurs when the copper in the penny comes in contact with oxygen.<span> </span>
Mutation is the only evolutionary mechanism that does little to change allele frequencies.
