Answer:
They tunnel through the soil, which allows air to enter.
Explanation:
Earthworms are considered to be agriculturally friendly living organisms that hold immense importance in improving the growth and productivity of plants.
They live in the soil and feed on the debris of plants such as manure, grasses, roots and dead leaves. They extensively channel and tunnel through soils while moving that causes loosening of the soil resulting in more aeration of the soil. The more the soil aeration is, the better soil drainage is.
Studies have shown that soil containing earthworms have ten times better drainage than soils that donot have earthworms. Therefore, C is the best option.

<span>Protein channels are needed to transport substances because it accelerates the transport process. Very few substances enter or leave cells without being attached to a transport protein. Different types of substances require different types of proteins to transport them. Protein channels transport water or ions downwards and ATP-powered pumps transport molecules or ions upwards. ATP generates energy to transport the molecules upwards. Gravity is used to transport the water molecules downwards. So, in a nutshell, if substances need to be transported from the top of the body downward, the force of gravity is used to transport the substances down. If substances need to be transported upwards, ATP, a coenzyme, is used to generate energy to transport the substance upwards</span>
Answer:
DNA fragments are negatively charged so the more for the positive electrode because all DNA fragments of the same amount of charge per mass does smart pigments move through the gel faster than large one
Answer:
They differ in sex chromosomes.
Explanation:
There are two types of chromosomes; autosomes(22 pairs) and sex chromosomes(1 pair).
While all the autosomes are same in the case of both male and female humans, sex chromosomes differ.
Human male has one X and one Y chromosome, while human female has two X chromosomes. Y is roughly shorter by half than the X chromosome.
