In cell biology, the primary difference between anaerobic and aerobic respiration is that aerobic respiration requires:
water |
|
oxygen |
|
sugar |
|
mitochondria |
Some plant cells produce their own energy through photosynthesis which is the process by which sunlight, carbon dioxide, and water react to make sugar and oxygen. Animal cells cannot produce their own energy and, instead, generate energy when mitochondria consume outside sugar and oxygen through aerobic respiration.
What part of the brain is responsible for for balance, movement, and muscle coordination?
brainstem |
|
medulla |
|
cerebellum |
|
cerebrum |
The cerebellum is a large cluster of nerves at the base of the brain that's responsible for balance, movement, and muscle coordination.
212°F is how many °C?
-100 |
|
0 |
|
100 |
|
\(135 {5 \over 9}\) |
The formula to convert from F° to C° is:
\(C° = {5 \over 9} (F° - 32)\)
plugging in our values gives:
\(C° = {5 \over 9} (212 - 32)\)
\(C° = {5 \over 9} (180) = {{180 \times 5} \over 9}\)
\(C° = {900 \over 9}\)
\(C° = 100\)
Which of the following is not a terrestrial planet?
Venus |
|
Mercury |
|
Earth |
|
Jupiter |
The four planets closest to the Sun (Mercury, Venus, Earth, and Mars) are called terrestrial (Earth-like) planets because, like the Earth, they're solid with inner metal cores covered by rocky surfaces.
In the Periodic Table of the Elements, atomic number is equal to which of the following?
number of protons + neutrons in the nucleus |
|
number of electrons orbiting the nucleus |
|
number of neutrons in the nucleus |
|
number of protons in the nucleus |
The Periodic Table of the Elements categorizes elements primarily by the number of protons in their nucleus (atomic number) and secondarily by the characteristics they exhibit.
