Answer:
The correct answer would be
- Concave lens for nearsightedness
- Convex lens for farsightedness
Nearsightedness or myopia is a condition in which a person can see the nearby objects clearly but is unable to see the objects present at a farther distance clearly.
It is usually caused due to elongation of the eyeball or when the lens becomes too curved.
It can be corrected by using a concave or diverging lens of appropriate power.
Farsightedness or hyperopia is a condition in which a person can see the distant objects clearly but is unable to see the nearby objects distance clearly.
It is usually caused due to shortening of the eyeball or when the lens loses its curvature.
It can be corrected by using a convex or converging lens of appropriate power.

You'll have to post a picture of the problem in order for me to be able to answer the question
Explanation:
Answer:
B. Neurons are cells that conduct electrical impulses.
Explanation:
Red blood cells carry oxygen throughout the body. White blood cells protect against pathogens and aid in blood clotting after injury. Blood cells cannot contract.
Neurons generate and conduct electrical impulses. So this one is correct.
Epithelial cells line the cavities and surfaces of blood vessels and organs, protect underlying tissue, regulate the exchange of chemicals, and secrete various substances. They do not react to stimuli, however neurons do.
Smooth muscles helps the skeleton move, smooth muscle is found in blood vessels and some organs, and cardiac muscle helps the heart beat and pump blood. They are however, not components of blood.
The hormone to be given is oxytocin. Oxytocin is a hormone produced by the paraventricular nuclei of the hypothalamus then stored in the posterior pituitary gland (along with antidiuretic hormone or vasopressin) that is responsible mainly for uterine contraction and milk ejection or letdown. Oxytocin induces contraction of the myoepithelial cells in the breast for milk letdown. On the other hand, there is upregulation of oxytocin receptors during parturition which makes the uterus more sensitive to oxytocin. Oxytocin is also known to induce labor and reduce post-partum bleeding.
Answer:
Guilt, self disgust, senslessness
Explanation:
Boston is plagued by feelings of guilt and self-disgust after the senseless, cold-blooded murder of Gumboot Dhlamini. He wants to know if Tsotsi shares these feelings. Boston asks Tsotsi many questions and this has a profound effect on Tsotsi, who does not remember much of his past.
