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
- <u>Goblet cells</u>
- <u>Glands of Manz</u>
- <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.

The idea of the atom is dated back way back to Aristotle's day as you know. But you may not have known that there were many ideas about what the atom would be. some believed that there was only 1 fundamental particle, others however believed that there was no atom at all and that you could just keep cutting the cake forever and never stop. Aristotle's four elements (fire earth air and water) where believed to be fundamental units that everything was made of. Different things such as would and glass would be a combination of earth fire and air perhaps. You may see now how different this idea is from the atom nowadays. there are magnitudes of different types of atoms. the 118 elements you know of are only a fraction of the thousands of isotopes (an isotope is an atom with slightly more or less nuetrons than the normal one with as many nuatrons as protons).
Plants have access to the resources they need to carry out photosynthesis, so they do not need to use chemosynthesis, which is a process that is helpful for organisms such as deep sea plant life that utilizes chemicals rather than sunlight and CO2.
Given what we know, if the newly discovered cell is undergoing photosynthesis, it should produce sugar molecules and oxygen.
<h3>Why should we expect these substances?</h3>
As with any cell that undergoes photosynthesis, the cells require some substances as the prerequisites and then expel others as the products. For photosynthesis, these substrates required are carbon dioxide and sunlight, as a result, they then produce sugar molecules as the final result, and release oxygen as a by-product.
Therefore, we can confirm that if the newly discovered cell is undergoing photosynthesis, it should produce sugar molecules and oxygen.
