In fermentation, what replaces oxygen in anaerobic respiration?
ascorbic acid or peptides |
|
starches |
|
lactic acid or alcohol |

The hottest of Earth's atmospheric layers is which of the following?
thermosphere |
|
mesosphere |
|
troposphere |
|
stratosphere |
Temperatures again increase with altitude in the thermosphere which is the hottest (4,530 °F / 2,500 °C) atmospheric layer due to direct exposure to the Sun's radiation. However, the gas in this layer is highly diluted so even though the atoms of gas may be very high in temperature, there are too few of them to effectively transfer much heat.
The ovum and oviduct are part of which bodily system?
reproductive |
|
circulatory |
|
nervous |
|
digestive |
Approximately every 28 days during female ovulation an egg (ovum) is released from one of the ovaries and travels through the oviduct (fallopian tube) and into the uterus. At the same time, the endometrial lining of the uterus becomes prepared for implantation.
The energy posessed by a ball on the window ledge of a tall building is an example of what kind of energy?
gravitational |
|
kinetic |
|
inherent |
|
potential |
Kinetic energy is the energy posessed by a moving object. Potential energy is stored energy in a stationary object based on its location, position, shape, or state.
