12)
receptor cell bodies are found in the dorsal ganglia which is F
relay cell bodies are found in the grey matter which is G
effector neuron bodies are found in the grey matter which is G
so the answer is D
13)
J is the dorsal root of the spinal nerve and contains the axons of the sensitive cells
H is the anterior root of the spinal nerve and contains the axons of the motor cells
therefore the answer is C
14)
F is the dorsal ganglion
I is the spinal nerve
hence, the answer is B
15)
first they come through the spinal nerve which is (I), then they go through the dorsal root, which is (J) then the impulses go through the grey matter(G) , they go through the anterior root(H) and finally through I
the answer is A
Answer: a. rna interference.
Rna interference <span> was known by other
names like <span>co-suppression because
it </span>has become evident that RNAi has immense potential in inhibiting desired
genes by neutralizing targeted mRNA molecules</span> Two types of small ribonucleic acid (RNA) molecules that are central to RNA interference
are miRNA and <span>siRNA. </span>
More than 4.2 million Americans aged 40 years and older are either legally blind (having best-corrected visual acuity of 6/60 or worse (=20/200) in the better-seeing eye) or are with low vision (having best-corrected visual acuity less than 6/12 (<20/40) in the better-seeing eye, excluding those who were categorized as being blind).
The leading causes of blindness and low vision in the United States are primarily age-related eye diseases such as age-related macular degeneration, cataract, diabetic retinopathy, and glaucoma. Other common eye disorders include amblyopia and strabismus.

Refractive Errors
Refractive Errors
Refractive errors are the most frequent eye problems in the United States. Refractive errors include myopia (near-sightedness), hyperopia (farsightedness), astigmatism (distorted vision at all distances), and presbyopia that occurs between age 40–50 years (loss of the ability to focus up close, inability to read letters of the phone book, need to hold newspaper farther away to see clearly) can be corrected by eyeglasses, contact lenses, or in some cases surgery. The National Eye Institute states that proper refractive correction could improve vision among 150 million Americans.
