Answer:

Option-C

Explanation:

Desertification refers to the formation of barren land from the arid land due to many factors which could be climatic or anthropogenic. The climate factors include no rainfall, arid conditions, less water and water bodies, overgrazing by animals and many others.

As a result of these factors, the plants die or are unable to hold the soil. This leads to loosening of soil which causes soil erosion. This converts the fertile land into infertile land and the land becomes barren.

Thus, desertification is the correct answer.

How do earthworms get their energy

What evidence is there that the universe is expanding? Explain.
Vsevolod [243]

This is evidenced by Doppler shift effect. This is the phenomenon where waves that are coming from an object that is accelerating towards your direction are heard at a higher frequency than that of objects moving away from you. This is the same for light (which also has wave-like properties). When observing distant galaxies, astronomers discovered that they all showed to be redshift (change in the frequency of light towards red color). This means that all galaxies are moving away from each other because the universe is expanding.

the testes hve both endocrine and exocrine functions. describe the endocrine and exocrine products tht come from the testes
qwelly [4]

The interstitial cells in the body produce testosterone for endocrine purposes. The seminiferous tubules' generation of spermatozoa constitutes the exocrine function.

<h3>What are Endocrine Functions of Testes?</h3>
  • The pituitary and hypothalamus regulate the amount of testosterone the testes make and secrete.
  • The pituitary gland receives a signal from the hypothalamus to release gonadotrophic chemicals (FSH and LH). The production of testosterone is stimulated by luteinizing hormone. The hypothalamus warns the pituitary gland to produce less LH, which instructs the testes to lower testosterone levels, if too much testosterone is being produced.
  • Boys' normal physical growth need testosterone. It is the principal androgen, which is a name for any chemical that promotes and/or supports the development of the male genitalia. Many of the processes that help a boy transition to manhood during puberty require testosterone, including:
  1. healthy growth of male genitalia
  2. growth of body and face hair
  3. reduction in voice volume
  4. Adam's apple development
