Meiosis is the process that occurs in sexually reproducing organisms in the sex cells of male and female organisms.

Variation occurs in an organism due to the process of crossing over which only occurs in meiosis in which the chromosomes between non-sister chromatids exchanged. Meiosis also causes genetic variation due to the process of recombination so in inheritance, meiosis has great importance and  impact on the shape and structure of organism.

In which oceanic zone do clams and crabs survive by burrowing in the sand?
Keith_Richards [23]

Answer:

Mesopelagic zone

Explanation:

The Mesopelagic zone, also referred to as the Twilight zone, is the second oceanic zone from the top, lying just bellow the Epipelagic zone. It is occupying the waters at depths between 200 meters and 1,000 meters. The sunlight is only managing to reach the top few meters of this zone, while the rest is not receiving any sunlight, thus this zone is not supporting the plant species because they need sunlight for the process of photosynthesis. There are lot of animal species that live in this zone though, and they are ll very well adapted for it, often having hard shells or heavily scaled bodies, larger lungs and heart, and very well developed gills. Some of the animals that live in here are the crabs and the clams. They have developed all the needed characteristics to live in this zone. Because they are prey to lot of larger animals, both the crabs and the clams have started to use the soft sediments at the bottom as cover, digging themselves below it, and mostly managing to evade trouble and end up as food for the other species.

Green plants need light in order to survive. Structures in the leaves absorb light, which in turn, helps plants make their own f
Lorico [155]

Answer:

The correct answer is the green light.

Explanation:

Plant themselves have a green color pigment in their leaves called chlorophyll which absorbs visible light.

Pigments absorb mostly the red and blue color light and reflect green light. This the reason why plants appear green to us and least likely to make food. Most of the autotrophs contain this green pigment.

Thus, the correct answer is the green light.
