Water moves from the soil to the leaves of mesophytes by osmosis and xylem conduction.

<h3>What are mesophytes?</h3>

Mesophytes are plants that are adapted to moderate water environments only. In other words, they cannot survive extremely or extremely wet environments.

Water moves from the soil to the leaves of mesophytes as follows:

1. Water moves into the root hair by osmosis

2. Water is conducted upward from the root hairs by special cells known as xylems.

3. Conducted water reaches various plant parts, including leaves.

Explanation:

The citric acid cycle or Kreb's cycle is the part of the cellular respiration. It is a sequence of chemical reaction which is used by all the aerobic organisms so as to store energy by the process of acetyl CoA oxidation derived by the process of fats, proteins and carbohydrates into forms like carbon dioxide and adenosine triphosphate (ATP).

The acetyl CoA is used in the process of synthesis of fatty acids. The citrate is used for the synthesis of cholestrol. The oxaloacetate and alpha ketogluterate are used for the synthesis of aminoacids. Succinyl CoA is used for the synthesis of poryphrins and fatty acids.

Which of these are the two major sources of nitrate pollution in rivers?
nikklg [1K]

Answer:

The correct answer is <em>c. animal wastes and fertilizers. </em>

Explanation:

Two major sources of nitrate pollution are farming and breeding activities. There are also certain industrial activities involved in nitrate pollution, but in general, these industries are related to agriculture.

The indiscriminate use of fertilizers for several years in intensive productions produce high nitrate concentration in soil and consequently elevate the risk of nitrate lixiviation.

Breeding animals produce nitrate pollution by their wastes, which accumulate and are not treated. These wastes include flesh, hair, feathers, skin, fat, liquids, excrements, among others. These wastes are an important source of nitrate.

In many cases, animal wastes are used by farmers as organic matter to improve their production. But excessive and incorrect use of it might produce severe damage in water sources.
