Answer:

<u>b. produce mucus to prevent the eyes from drying out.</u>

Explanation:

Conjunctiva is a<u> mucous membrane which covers the underside of the eyelids, the sclera (the white of the eye) upto the limbus</u> (the junction of cornea/ transparent portion of the eye and sclera).

It contains <u>various mucin glands which produce mucous</u> responsible for moistening the conjunctiva. The various mucin glands present in conjunctiva are

  1. <u>Goblet cells</u>
  2. <u>Glands of Manz</u>
  3. <u>Crypts of Henle</u>

<u></u>

<u>QUESTION:</u>

<u>a. produce tears to lubricate the eyes.</u>

This is the inappropriate answer choice as tears are mostly produced by the lacrimal glands. Only a very small proportion are produced by the conjunctiva.  

<u>b. produce mucus to prevent the eyes from drying out.</u>

This is the<u> correct answer and appropriate choice</u> as mucous from conjunctival glands helps in preventing dryness of eyes.

<u>c. lubricate the eyelids so they do not stick together.</u>

This is the inappropriate answer choice.

<u>d. produce sweat to cool the eyelids.</u>

This is the incorrect answer choice as it is not the function of conjunctiva.

Which of the following statements about natural selection is TRUE?
diamong [38]

Answer:

A. Natural selection results in those individuals within a population who are best-adapted surviving and producing more offspring. The traits that promote survival are heritable.

Explanation:

Natural selection works on the genetic variations that are already present in the natural populations. Some organisms of a population are more likely to produce more offspring than the others. This is due to the presence of beneficial genetic traits in these individuals that impart survival and reproductive fitness to them. Natural selection favors those individuals. Over the generations, the frequency of the beneficial genetic trait in the population increases.

Karolina [17]
A large deposit of sand and soil formed at the end of a river is a delta. When a river empties into the ocean, the current carrying smaller particles, such as soil and sand, slows down and eventually stops, causing these particles to be dropped off on the shore. This eventually leads to a triangular deposit, usually referred to as the mouth of the river.
