Answer the following question given this paragraph: Temperature falls from the equator to the poles. Global air currents create wet and dry zones at different latitudes. They also create global winds. Q: What creates wet and dry zones at different latitudes? Choices: - jet stream - trade winds - horse latitudes - global air currents A:
global air currents
Answer the following question given this paragraph: Therian mammals are viviparous. They give birth to an embryo or infant rather than laying eggs. The female reproductive system of a therian mammal includes a uterus and a vagina. There are two groups of therian mammals: placental mammals and marsupials. Q: What are the two groups of therian mammals? Choices: - felines and canines - monotremes and mollusks - dolphins and whales - placental mammals and marsupials A:
placental mammals and marsupials
Q: Answer the following question given this paragraph: A series of chemical reactions where an initial amount of copper reacts with nitric acid, goes into solution, and disappears. Then a series of reactions proceed, only to have the copper metal recovered. The copper cycle is a good illustration of how mass is conserved in a given chemical reaction. Q: The cycle of copper reacting is a good example of what principle? Choices: - law of inertia - conservation of energy - conservation of momentum - conservation of mass A:
A: conservation of mass
Question: Answer the following question given this paragraph: Figure below shows a simple diagram of the expanding universe. Imagine a balloon covered with tiny dots. When you blow up the balloon, the rubber stretches. The dots slowly move away from each other as the space between them increases. In an expanding universe, the space between galaxies is expanding. We see this as the other galaxies moving away from us. We also see that galaxies farther away from us move away faster than nearby galaxies. Q: How does the distance between galaxies change as the universe expands? Choices: - it decreases - it is unchanged - it becomes irrelevant - it increases A:
Answer: it increases

Answer the following question given this paragraph: Transcription is the first step in protein synthesis. It takes place in the nucleus. During transcription, a strand of DNA is copied to make a strand of mRNA. How does this happen? It occurs by the following steps, as shown in Figure below . Q: What is the first step in protein synthesis? Choices: - reproduction - differentiation - mutation - transcription A:
**Answer**
transcription
Q: Answer the following question given this paragraph: How do you think scientists test whether two populations are separate species? They bring species from two populations back together again. If the two populations do not mate and produce fertile offspring, they are separate species. Q: If two populations do not mate and produce fertile offspring, what results? Choices: - same species - large species - small species - separate species A:
A: separate species
