Describe how mutation and genetic recombination increase genetic variation
Gekata [30.6K]

Answer:

Genetic variation can be caused by mutation (which can create entirely new alleles in a population), random mating, random fertilization, and recombination between homologous chromosomes during meiosis (which reshuffles alleles within an organism's offspring).

A sample of soil from a C horizon is light brown in color and has a high content of a mineral called feldspar. Which of the foll
vaieri [72.5K]

Answer: C. The C horizon is very deep.

Horizons are the layers of soil develops as a result of soil formation. Horizon lies parallel to the earth surface. Each horizon differs from the other on the basis of amount or organic matter present, color of the soil, texture of soil and other components making up horizon, and amount and type of minerals present in the soil.

C horizon is the horizon that lies deeper region of the collective soil horizon. It consist of unweathered or partially weathered rocks or their aggregates. Therefore, it retains the original chemical composition of the parent rock. This results in the higher mineral content as compared to other horizons. This horizon also lacks the organic matter as no or very little decomposition activity of plant and animal matter takes place. Therefore, color of soil in this horizon in the absence of organic matter remains light.

Hence, a sample of soil from a C horizon is light brown in color and has a high content of a mineral called feldspar is because of the fact that the C horizon is very deep.

What's the answer to this question
Flauer [41]
The answer is C. Thermal energy is transferred to her face by radiation, and thermal energy is transferred to the bottoms of her feet by conduction. 

Conduction is a method of transferring heat by using the collision of molecules and free electrons (depending on the material). Heat is usually transferred by conduction if both objects are in contact with each other that way the molecules can collide and spread the kinetic energy thus raising their internal heat. So, since the feet and the sand are in contact, so the heat should be transferred by conduction. However, air is a very poor heat conductor, it cannot transfer heat efficiently, therefore, the first answer is not conduction. 

Radiation is a method of transferring heat too but using electromagnetic waves. It works great even in the air, or even with vacuum space. The sun shining from outer space to earth through the vacuum space is also by radiation. So, the first answer is radiation. 

The answer is C, hope it helps!
