Answer:
Megaloblastic anemia is as a result of deficiency of mature red blood cells characterized by red blood cells that are larger than normal.
Explanation:
Megaloblastic anemia is a type of anemia (blood disorder) resulting from the number of red blood cells being lower than normal. This red blood cells aid in the transportation oxygen round the body. Megaloblastic anemia is as a result of deficiency of mature red blood cells characterized by red blood cells that are larger than normal. It is caused by deficiency in vitamin B-12 or folate which are necessary for producing healthy red blood cells. Since red blood cells are too large, they are not produced properly, as a result oxygen is not distributed properly.

Answer: The procedure RJ is preparing to undergo is called KIDNEY TRANSPLANT.
Explanation:
RJ was diagnosed with renal failure for the past 10 years. For him to have been in this condition for a period of 10 years depicts chronic renal failure. This is a type of kidney disease in which there is progressive loss of function of more and more nephrons that gradually decreases overall kidney function with time. The following can cause chronic renal failure:
--> Metabolic disorders: these include diabetes mellitus, obesity
--> Hypertension
--> Infections: Example is tuberculosis
--> Urinary tract obstruction
--> Congenital disorders
In chronic renal failure, the irreversible decrease in the number of functional nephrons eventually leads to KIDNEY TRANSPLANT.
Kidney transplant is a surgical procedure which is performed by a nephrologist where by a kidney from a compatible donor is transferred to a recipient. This procedure requires only one kidney from the donor, which when surgically implanted in RJ it would help perform blood filtration.
Answer:
The Aplysia withdrawing it's gills is demonstrating a gill and siphon withdrawal reflex (GSWR) phenomenon
Explanation:
The hill and siphon withdrawal reflex (GSWR) is involuntary and a defensive reflex. This reflex causes delicate siphon and gill to be retracted when an animal is disturbed.
A two-component reflex is triggered when weak or moderate stimulus is applied to a siphon or the mantle shelf. These two components consist of two reflex acts, the siphon-withdrawal reflex and the gill-withdrawal reflex. Together they often form a reflex pattern with short latency that protects the animals gill and siphon to potentially threatening stimuli.
An habituation in an Aplysia californica for example is which is an Aplysia gills is when a stimulus is presented continously to an animal and there is a progressive decrease in response to that particular stimulus.
