Answer the following question given this paragraph: Nearly all fish reproduce sexually, and most species have separate sexes. Those without separate sexes avoid self-fertilization by producing sperm and eggs at different times. Each fish typically produces a large number of gametes. In most fish species, fertilization takes place externally. These fish are oviparous . Eggs are laid and embryos develop outside the mother's body. In a minority of fish, including sharks, eggs develop inside the mother's body but without nourishment from the mother. These fish are ovoviviparous . Q: How do the vast majority of fish reproduce? Choices: - by budding - asexually - cloning - sexually A:
sexually
Answer the following question given this paragraph: The ideal gas law can also be used to determine the densities of gases. Density, recall, is defined as the mass of a substance divided by its volume:. Q: What is idefined as the mass of a substance divided by its volume? Choices: - weight - height - length - density A:
density
Q: Answer the following question given this paragraph: An air mass takes on the conditions of the area where it forms. For example, a continental polar air mass has cold dry air. A maritime polar air mass has cold moist air. Which air masses have warm moist air? Where do they form?. Q: What kind of air does a continental polar air mass hold? Choices: - cool moist air - frigid wet air - warm dry air - cold dry air A:
A: cold dry air
Question: Answer the following question given this paragraph: The measure of how quickly a nucleus decays is given by the half-life of the nucleus. One half-life is the amount of time it will take for half of the radioactive material to decay. Q: What do we call the amount of time it will take for half of the radioactive material to decay? Choices: - one partial-life - one full-life - one quarter-life - one half-life A:
Answer: one half-life

Answer the following question given this paragraph: Migration refers to seasonal movements of animals from one area to another. Migrants typically travel long distances, and travel the same paths each seasonal cycle. Usually, the migrants move to another area in order to find food or mates. Many birds, fish, and insects migrate. Mammals such as whales and caribou migrate as well. Figure below shows the migration route of a bird called a godwit. Another example of a behavior with a yearly cycle is hibernation. Hibernation is a state in which an animal's body processes are slower than usual, and its body temperature falls. An animal uses less energy than usual during hibernation. This helps the animal survive during a time of year when food is scarce. Hibernation may last for weeks or months. Animals that hibernate include species of bats, squirrels, and snakes. Most people think that bears hibernate. In fact, bears do not go into true hibernation. In the winter, they go into a deep sleep. However, their body processes do not slow down very much. Their body temperature also remains about the same as usual. Bears can be awakened easily from their winter sleep. Q: The seasonal movements of animals from one area to another is referred to as? Choices: - mitigation - hybernation - echolocation - migration A:
**Answer**
migration
