The large intestine does which of the following?

82% Answer Correctly

processes the physical waste produced by digestion

breaks down proteins

breaks down starches

Convert 0C° to F°.

72% Answer Correctly

16

0

32

-32


Solution

To convert from C° to F° use:

\(F° = {9 \over 5}C° + 32\)

\(F° = {9 \over 5}(0) + 32\)

\(F° = 0 + 32 = 32\)

The two heart chambers that collect blood are called:

46% Answer Correctly

ventricles

atria

aorta

valves


Solution

The heart is the organ that drives the circulatory system. In humans, it consists of four chambers with two that collect blood called atria and two that pump blood called ventricles. The heart's valves prevent blood pumped out of the ventricles from flowing back into the heart.

Which of blood component fights infection?

89% Answer Correctly

red blood cells

white blood cells

platelets

plasma


Solution

Blood is created in bone marrow and is made up of cells suspended in liquid plasma. Red blood cells carry oxygen, white blood cells fight infection, and platelets are cell fragments that allow blood to clot.


5

A dominant trait will be expressed when paired with:

74% Answer Correctly

a chromosome

a dominant trait

a gene

a recessive trait


Solution

The traits represented by genes are inherited independently of each other  (one from the male and one from the female gamete) and a trait can be dominant or recessive.  A dominant trait will be expressed when paired with a recessive trait while two copies of a recessive trait (one from each parent) must be present for the recessive trait to be expressed.
