Answer:
The answer is 3:2
Explanation:
A cubic cell has 6 sides
= 6 side²
= 6 × 4²
= 6 × 16
= 96 mm²
Volume of a cubic cell
= side³
= 4³
= 64 mm³
The ratio of the surface area to volume of imaginary cubic cell is therefore:
= 96/64
= 3/2
= 3:2

Hope that helps you out
Answer: If it is almost impossible for a favorable trait to get passed down to offspring due to reproductive struggles, the species would not be able to undergo natural selection due to a lack in appearance of a trait.
Explanation:
If there are only two organisms with the adaptation, both of which lack any reproductive abilities, the odds of most of the species <em>not</em> dying out are very low. Only those two will have the adaptation and they rest will die out.

The correct answer is - a. terrigenous sediment.
The terrigenous sediments are sediments that are derived from the land masses, the continents. The name terrigenous itself suggests that, as terra means land/Earth.
The source of the terrigeous sediments are numerous, including the volcanoes, sediments carried by icebergs, glacial grinding, the weathering of the rocks, as well as the wind blow dust.
Most of these sediments end up dispersed and deposited on the continental land masses and on the coastlines, though parts of them also end up in the water bodies.
