Answer the following question given this paragraph: Early vertebrates were ectothermic. Ectothermy means controlling body temperature to just a limited extent from the outside by changing behavior. For example, an ectotherm might stay in the shade to keep cool on a hot, sunny day. On a cold day, an ectotherm might bask in the sun to warm up, like the snake in Figure below . Almost all living fish, amphibians, and reptiles are ectothermic. They can raise or lower their body temperature by their behavior but not by very much. In cold weather, an ectotherm cools down. As its body temperature drops, its metabolism slows down and it becomes inactive. Q: What type of vertebrates control body temperature to just a limited extent from the outside by changing behavior? Choices: - etheric - endothermic - mimetic - ectothermic A:
ectothermic
Answer the following question given this paragraph: Plants also detect and respond to the daily cycle of light and darkness. For example, some plants open their leaves during the day to collect sunlight and then close their leaves at night to prevent water loss. Environmental stimuli that indicate changing seasons trigger other responses. Many plants respond to the days growing shorter in the fall by going dormant . They suspend growth and development in order to survive the extreme cold and dryness of winter. Dormancy ensures that seeds will germinate and plants will grow only when conditions are favorable. Q: What do plants do to prevent water loss at night? Choices: - close their stems - shed their petals - open their petals - close their leaves A:
close their leaves
Q: Answer the following question given this paragraph: Ladybugs, also known as ladybird beetles, have a life cycle of four to six weeks. In one year, as many as six generations of ladybird beetles may hatch. In the spring, each adult female lays up to 300 eggs in small clusters on plants where aphids are present. After a week, the wingless larvae hatch. Both the ladybird beetle larvae and adults are active predators, eating only aphids, scales, mites and other plant-eating insects. The ladybugs live on the vegetation where their prey is found, which includes roses, oleander, milkweed and broccoli. Adult ladybugs don't taste very good. A bird careless enough to try to eat one will not swallow it. Q: How many weeks are in the life cycle of ladybugs Choices: - two to four - nine to six - three to six - four to six A:
A: four to six
Question: Answer the following question given this paragraph: As expected, the entropy values for solids are low, the values for gases are high, and the ones for liquids are intermediate. Another observation can be made by looking at the three hydrocarbon gases at the end of the table. For similar molecules, a higher molecular weight generally leads to a larger standard entropy value. Although this is a drastic oversimplification, we can think of this in terms of the electrons that make up each molecule. A larger molecular weight generally means more protons, which also means more electrons. There are more ways to arrange a large number of electrons within a molecule than there are to arrange a smaller number. Although these arrangements are heavily constrained by the positions of the various nuclei, there is still an overall trend for larger molecules to have higher entropy values. Q: Which state of matter has an intermediate level of entropy between solid and gas? Choices: - plasma - water - metal - liquid A:
Answer: liquid

Q: Answer the following question given this paragraph: Worldwide Distribution of Malaria. This map shows where malaria is found. The area is determined by the mosquito vector. The mosquito can live year-round only in the red-shaded areas. Q: The vector of what organism is significant on a map showing the location of malaria? Choices: - virus - worm - fungi - mosquito A:
A: mosquito
