Answer the following question given this paragraph: In most species, one or both parents take care of the eggs. They sit on the eggs to keep them warm until they hatch. This is called incubation. After the eggs hatch, the parents generally continue their care. They feed the hatchlings until they are big enough to feed on their own. This is usually at a younger age in ground-nesting birds such as ducks than in tree-nesting birds such as robins. Q: When animals use incubation, how do they generally give birth to their young? Choices: - copying - live - division - eggs A:
eggs
Q: Answer the following question given this paragraph: All that changed when plants moved from water to land. This may have happened by 500 million years ago or even earlier. On land, everything was wide open. There were no other living things. Without plants, there was nothing for other organisms to eat. Land could not be colonized by other organisms until land plants became established. The earliest land plants may have resembled the modern liverworts in Figure below . Q: Land could not be colonized by other organisms until what became established? Choices: - gases - carbon dioxide - oxygen - plants A:
A: plants

Answer the following question given this paragraph: Spores may be dispersed by moving water, wind, or other organisms. Some fungi even have "cannons" that "shoot" the spores far from the parent organism. This helps to ensure that the offspring will not have to compete with the parents for space or other resources. You are probably familiar with puffballs, like the one in Figure below . They release a cloud of spores when knocked or stepped on. Wherever the spores happen to land, they do not germinate until conditions are favorable for growth. Then they develop into new hyphae. Q: What type of organism has spores that are spread by water and wind? Choices: - Plants - Trees - yeast - fungi A:
**Answer**
fungi
Q: Answer the following question given this paragraph: Q: What regulates homeostasis and basic survival behaviors? Choices: - hippocampus - mitosis - cell membrane - hypothalamus A:
