Answer:

True

Explanation:

<em>The life cycles of sexually producing organisms generally involve alternation between the haploid and diploid generations.</em>

<u>Sexual reproduction involves the fusion of gametes - fertilization. The gametes are haploid (n) and are usually formed by the reductional division (meiosis) of diploid (2n) sex cells. </u>

Haploid gametes represent the haploid stage of the life cycles of sexually reproducing organisms.  During fertilization, the male and female gametes fuse together to form a diploid zygote. The zygote then continues to divide equationally (mitosis) and differentiates to give rise to a baby and eventually to either male or female adult organism.

Explanation:

Conjuctiva is that thin transparent mucous membrane that covers both the anterior surface and the inner surface of the eyelid. Conjuctiva is an important component of the eye that keeps the inner surface of the eyelids and the front surface of the eye moist and lubricated. It also helps protect the eye from foreign particles and from infection.

The part of the conjunctiva that covers the eyelids and is reflected over the anterior surface of the eyeball is called the bulbar conjunctiva. The part that is found coating the inner surfaces of the eyelids is called the palpebral conjunctiva.
