The large intestine does which of the following?
breaks down proteins |
|
breaks down fats |
|
breaks down starches |
|
processes the physical waste produced by digestion |
The large intestine (colon) follows the small intestine and processes the physical waste produced by digestion, absorbing water and minerials that remain back into the body. Solid waste is then stored in the rectum while liquid waste is stored in the bladder.
Which of these does not contain oxygenated blood?
left ventricle |
|
pulmonary vein |
|
right atrium |
|
aorta |
To provide oxygen to the body, blood flows through the heart in a path formed by the right atrium → right ventricle → lungs → left atrium → left ventricle → body. When blood enters the right side of the heart it is deoxygenated. It enters the left side of the heart oxygenated after traveling to the lungs.
Cellular fermentation takes place:
anaerobically |
|
aerobically |
|
in the presence of oxygen |
|
in plant cells |
If no oxygen is present, cellular respiration is anaerobic and will result in fermentation where either lactic acid or alcohol is used instead of oxygen.
The angle of reflection is equal to which the following?
90° |
|
focal point |
|
angle of incidence |
|
refractive index |
The law of reflection specifies how waves, including light waves, bounce off of surfaces. Specifically, the angle of incidence of the approaching wave is equal to the angle of reflection of the reflected wave as measured from a line perpendicular (90°) to the surface.
These clouds grow upward and can develop into cumulonimbus or thunderstorm clouds.
cirrus clouds |
|
stratus clouds |
|
nimbus clouds |
|
cumulus clouds |
Cumulus clouds are large, puffy, mid-altitude clouds with a flat base and a rounded top. These clouds grow upward and can develop into a cumulonimbus or thunderstorm cloud.
