Which of the following lists best illustrates the idea of increasing levels of complexity?
Organs, organelles, organ systems, cells, tissues.
Cells, tissues, organelles, organs, organ systems.
Organelles, cells, tissues, organs, organ systems.
Tissues, cells, organs, organelles, organ systems.
The Correct Answer is C
This list best illustrates the idea of increasing levels of complexity because it follows the biological hierarchy of organization from the simplest to the most complex units of matter.
Each level is composed of units from the previous level and has emergent properties that are not present in the lower levels.
Choice A is wrong because it reverses the order of organelles and cells. Organelles are subcellular structures that perform specific functions within cells.
Cells are the basic units of life that can carry out all the processes of living organisms.
Choice B is wrong because it reverses the order of tissues and organelles. Tissues are groups of similar cells that work together to perform a common function. Organelles are more basic than tissues and are found within cells.
Choice D is wrong because it reverses the order of organs and organelles.
Organs are structures composed of two or more types of tissues that perform a specific function or function.
Organelles are more basic than organs and are found within cells.

Correct Answer is D
Explanation
This is because blood type AB has both A and B antigens on the surface of red blood cells.
Antigens are protein molecules that can trigger an immune response if they are foreign to the body.
Choice A is wrong because antigen B only is present in blood type B.
Choice B is wrong because neither antigens A nor B are present in blood type O.
Choice C is wrong because antigen A only is present in blood type A.
Normal ranges for blood types vary by population, but according to the NHS, about 3% of people in the UK have blood type AB.
Correct Answer is B
Explanation
Persons with type AB blood are sometimes called universal recipients, not donors. This means they can safely receive a blood transfusion using any other blood type. Choice A is wrong because it confuses type AB blood with type O negative blood.
Type O negative blood is considered the universal donor type because it has no antigens on the surface of red blood cells and can be given to people of any blood type.
Type AB-positive blood is also considered the universal plasma donor type because it has both A and B antigens and can be given to patients with any blood type.
Plasma is the liquid part of blood that carries cells and proteins throughout the body.
The presence or absence of antigens and the Rh factor determine how a person’s immune system reacts to a blood transfusion or organ transplant.
Antigens are substances that can trigger an immune response if they are foreign to the body.
The Rh factor is a protein that can be either present (+) or absent (-) on the surface of red blood cells.
