Someone who has Rh-factor __________ blood cannot receive blood with a __________ type.

57% Answer Correctly

antigen, negative

positive, antigen

positive, negative


Solution

Blood transfer is limited by the type and Rh factor of the blood. Someone who has Rh-factor negative blood cannot receive blood with a positive type but a person with Rh-factor positive type blood can receive Rh-negative blood. Type O negative blood is the universal donor because it can be given to a person with any blood type. Type AB positive is the universal recipient meaning someone with this blood type can receive any other type of blood.

83% Answer Correctly

one is inherited, the other is learned

one controls voluntary activity, one controls involuntary activity

one controls thinking, the other controls feeling

each belongs to a different nervous system

3

DNA is encoded through a combination of which of the following?

47% Answer Correctly

nucleotides

gametes

helix

genes


Solution

Deoxyribonucleic acid (DNA) is the molecule that contains genetic information. DNA is encoded through a combination of nucleotides that bind together in a specific double helix pattern.


4

The envelope of gases surrounding the planet is called the:

79% Answer Correctly

geosphere

lithosphere

atmosphere

hydrosphere


Solution

The biosphere is the global ecological system integrating all living beings and their relationships. This includes their interactions with the lithosphere (the rigid outer part of the earth, consisting of the crust and upper mantle), hydrosphere (all surface water), and atmosphere (the envelope of gases surrounding the planet).

In the pancreas, lipase converts fat to:

64% Answer Correctly

amino acids

simple sugars

glycerol and fatty acids

complex carbohydrates


Solution

The acids produced by the pancreas contain several enzymes that aid in digestion.  Lipase converts fat to glycerol and fatty acids. Pancreatic amylase breaks down complex carbohydrates into simple sugars. Trypsin converts polypeptides (the building blocks of protein) into amino acids.
