An individual with which of the following blood types can receive all types of blood?
AB positive
A positive
B negative
O negative
The Correct Answer is A
a. AB positive: Individuals with AB positive blood are universal recipients. They have A and B antigens on their red blood cells but no antibodies (anti-A or anti-B) in their plasma. Therefore, their body will not reject blood types A, B, AB, or Rh positive or negative.
b. A positive: Individuals with A positive blood can only receive A positive or O positive blood. Their plasma contains anti-B antibodies, which would attack blood types B and AB.
c. B negative: Individuals with B negative blood can receive B negative or O negative blood. Their plasma contains anti-A antibodies, which would attack blood types A and AB. The Rh factor is another compatibility consideration, but the question specifies positive.
d. O negative: Individuals with O negative blood are universal donors but not universal recipients. Their red blood cells lack A and B antigens, so they can be donated to anyone. However, their plasma contains anti-A and anti-B antibodies, so they can only receive O negative blood.

Correct Answer is B
Explanation
a: Artificial passive - Artificial passive immunity involves the transfer of pre-made antibodies from one individual to another, such as through injection of immune serum or administration of antibodies produced in a laboratory.
b. Artificial active: Artificial active immunity is acquired through vaccination, where a person's immune system is exposed to a weakened or inactive form of a pathogen, such as the varicella (chickenpox) virus, to stimulate an immune response and the production of antibodies.
c: Natural active - Natural active immunity occurs when a person is exposed to a pathogen in the environment and develops an immune response, such as contracting and recovering from a disease like chickenpox.
d: Natural passive - Natural passive immunity involves the transfer of antibodies from a mother to her baby, such as through breastfeeding or placental transfer of antibodies during pregnancy.
Correct Answer is A
Explanation
a. Cartilage: Cartilage is a type of connective tissue found at the ends of bones in joints. It provides a smooth, elastic surface that cushions the bones and reduces friction during movement.
b. Tendon: Tendons are tough, fibrous bands that connect muscles to bones. They do not reduce friction at joints.
c. Fibrillin: Fibrillin is a protein component of connective tissue, but it's not a specific structure like cartilage and doesn't directly reduce friction in joints.
d. Osteocytes: Osteocytes are mature bone cells. They are not located at joints and don't play a role in friction reduction.
