Answer:
<em>A</em><em>.</em>
<em>The correct answer would be A. ratio of surface area to volume .The cells are mostly spherical in shape.The surface area of the sphere = 4πr²The volume of the sphere = (4πr³)/3Thus, the increase in size would increase the volume (r³) more as compared to the increase in surface area (r²).The ratio of surface area to volume would decrease due to which the diffusion rate would not be efficient enough to distribute the essential elements throughout the volume of the cell.</em>

The correct answer for this question is D
The temperate forest occurs across north America, Europe and Asia. This biome consist of evergreen conifers with needle like leaves which are able to tolerate wide fluctuation of temperature and light. Some vegetation of temperate biome are Pine, Fir and Hemlock. The trees and shrubs of temperate forest usually shed their leaves with the onset of autumn and new leaves are produced in early spring
Taiga is the Russian word for forest and is the largest biome in the world. This biome contain mostly coniferous trees. These conifers contain long, thin waxy needles. The wax gives them protection against freezing temperature and from drying out. They do not sheds their leaves in winter and keep their needles all year long.
Answer:
D. By blocking fish migration.
Explanation:
The pictured waterfalls are artificial.
The construction of the wall to raise water level for the falls to be created cuts the contact between marine organisms.
The fish on the other end of the fall cannot freely migrate to the other side.
This is because the falls are too dangerous for them and can lead to their death.
This means that the pictured method of power generation is not environmental friendly.
