Answer:

Option (A)

Explanation:

The factors namely the temperature and rainfall plays a very significant role in maintaining the quality of the soil. A comparatively warmer temperature along with abundance of rainfall helps the soil to gain nutrients and increases its fertility. But a cooler temperature with lesser amount of rainfall does not provide the necessary elements to the soil. As a result of which the soil loses its fertility. In nature, these two factors occurs simultaneously, that controls the chemical composition of the soil.

Thus, the correct answer is option (A).

Answer:

Fibrous

Explanation:

Proteins are assembled according to their functions. Fibrous proteins usually provide protection and support to cells. They are made up of polypeptides that have elongated shape and assembles in large cables or threads. These proteins are differentiated from globular proteins by their globular form and repeated units of amino acids.

For example the fibrous proteins involved in horns, hair and nails is alpha-keratin.  Elastin found in skin and ligament is also a fibrous protein. Collagen includes collagen fibrils that have tensile strength of steel is also a fibrous protein found in cartilages and bones.

Dimas [21]

Answer:

In my own words, this summary equation tells me that:

When glucose reacts with oxygen, carbon (IV) oxide and water are given off and energy is produced.

Explanation:

Cellular respiration is known to be a metabolic reaction which actually occur in the cells of living organisms whereby chemical energy is converted into energy (ATP) and certain waste products, carbon (IV) oxide and water are released. We can simply put that cellular respiration is a process of converting sugars to energy. In the giving equation, we can see that glucose which is a sugar reacts with oxygen to give CO₂ and H₂O.
