Answer:

True

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.

Question 3
shepuryov [24]

The statements Molecule B can be used to produce molecule A and Molecules B and C interact so that amino acids can be joined together are TRUE regarding the structures shown in the diagram (Options B and E).

<h3>What are transcription and translation?</h3>

Transcription is the process by which a DNA template (molecule B) can be used to synthesize a complementary RNA (molecule A), while translation is a process in which an sequence is used as templates to generate a protein, which requires tRNAs (molecule C) to trasnport amino acids to the ribosomes.

Therefore, with this data, we can see that DNA is molecule B used to create RNA, which is molecule A, while tRNA is represented by molecule C and it is used during translation.

An example of a false negative is taking an HIV test and having the test come back negative to say the patient is clean, but in reality they have HIV. Another example of a false negative is a woman taking a pregnancy test saying "not pregnant" (i.e. test is negative), but she actually is pregnant. Between those two examples, it is better to have a false negative pregnancy test because it is non life threatening.

A false positive example would be getting bad news you have cancer, when you actually don't have cancer. Another false positive example is a test saying you have a cold virus, when in actuality you don't. The first example mentioned would have the patient likely go through intense chemo treatments which would greatly affect their livelihood. The second example is a more harmless false positive as it would involve at most a flu shot if anything.
