A person with type AB blood can successfully receive blood from:
All blood types.
Only type O blood.
Only two of the blood types.
Only one of the blood types.
The Correct Answer is A
A person with type AB blood can successfully receive blood from all blood types.
This is because type AB blood has both A and B antigens on the surface of red blood cells, and therefore does not have antibodies against either antigen in the plasma.
Type AB blood is also called the universal recipient.
Choice B is wrong because type AB blood can receive more than just type O blood.
Type O blood is the universal donor, meaning it can be given to anyone, regardless of their blood type.
Choice C is wrong because type AB blood can receive more than just two of the blood types. Type AB blood can receive both A and B blood, as well as O and AB blood.
Choice D is wrong because type AB blood can receive more than just one of the blood types. Type AB blood can receive any blood type without problems.
Normal ranges for blood types vary by population, but generally, type O is the most common, followed by type A, type B, and type AB.

Correct Answer is A
Explanation
Calcitonin is a hormone that protects against excessive blood calcium levels by inhibiting bone turnover and decreasing reabsorption.
It is produced by the thyroid gland and acts on both osteoclasts and osteoblasts.
Choice B is wrong because parathyroid hormone (PTH) stimulates both resorption and formation of bone, and controls the level of calcium in the blood.
Choice C is wrong because thyroxine is a thyroid hormone that is required for skeletal maturation and influences adult bone maintenance but does not directly affect calcium deposition into bone.
Choice D is wrong because insulin is a hormone that regulates both bone formation and bone resorption but does not specifically stimulate calcium deposition into bone.
Correct Answer is B
Explanation
Innate defenses counter specific disease-causing agents, whereas adaptive defenses include mechanical and chemical barriers.
Choice A is wrong because it confuses the two types of defenses.
Innate defenses are nonspecific and include physical barriers such as the skin, molecules that are toxic to invaders, and phagocytic cells that ingest invaders.
Adaptive defenses are specific and are activated by the innate immune system.
They involve the production of antibodies and specialized cells that recognize and eliminate specific pathogens.
Normal ranges are not applicable in this question as it is about the definitions of innate and adaptive defenses.
