Answer the following question given this paragraph: Figure 23.12 The dinoflagellates exhibit great diversity in shape. Many are encased in cellulose armor and have two flagella that fit in grooves between the plates. Movement of these two perpendicular flagella causes a spinning motion. Q: What is observed when two perpendicular flagella moves? Choices: - turning motion - pushing motion - shaking motion - spinning motion A:
(Answer)
spinning motion

Ques:Answer the following question given this paragraph: Research is being done into alternative crops for biofuels. A very promising alternative is algae. Algae appears to be a better biofuel than corn. Algae is much easier to convert to a usable fuel. Growing algae requires much less land and energy than crops. Algae can be grown in locations that are not used for other things. For example, they can be grown in desert areas where food crops are not often grown. Corn must be grown where food crops are grown. This can reduce the land and water available for growing food. Algae can be fed agricultural and other waste, so valuable resources are not used. Much research is being done to bring these alternative fuels to market. Q: What is algae easier to covert into that corn is currently used for? Choices: - oil - food - sugar - fuel A:

Ans:fuel
Question: Answer the following question given this paragraph: Figure 15.2 All animals that derive energy from food are heterotrophs. The (a) black bear is an omnivore, eating both plants and animals. The (b) heartworm Dirofilaria immitis is a parasite that derives energy from its hosts. It spends its larval stage in mosquitos and its adult stage infesting the hearts of dogs and other mammals, as shown here. (credit a: modification of work by USDA Forest Service; credit b: modification of work by Clyde Robinson). Q: All animals that derive energy from food are classified as what? Choices: - lifeforms - paleotrophs - heliotrophs - heterotrophs A:
Answer:
heterotrophs
