Answer the following question given this paragraph: Currents are like rivers flowing through the ocean. Rivers always flow downhill because of gravity. What do you think causes ocean currents to flow?. Q: What causes rivers to always flow downhill? Choices: - slope - pressure - diffusion - gravity A:
gravity
Answer the following question given this paragraph: solution. In addition, sucrose does not undergo reactions that are typical of aldehydes and ketones. Therefore, sucrose is a nonreducing sugar. The hydrolysis of sucrose in dilute acid or through the action of the enzyme sucrase(also known as invertase) gives an equimolar mixture of glucose and fructose. This 1:1 mixture is referred to as invert sugar because it rotates plane-polarized light in the opposite direction than sucrose. The hydrolysis reaction has several practical applications. Sucrose readily recrystallizes from a solution, but invert sugar has a much greater tendency to remain in solution. In the manufacture of jelly and candy and in the canning of fruit, the recrystallization of sugar is undesirable. Therefore, conditions leading to the hydrolysis of sucrose are employed in these processes. Moreover, because fructose is sweeter than sucrose, the hydrolysis adds to the sweetening effect. Bees carry out this reaction when they make honey. The average American consumes more than 100 lb of sucrose every year. About twothirds of this amount is ingested in soft drinks, presweetened cereals, and other highly processed foods. The widespread use of sucrose is a contributing factor to obesity and tooth decay. Carbohydrates such as sucrose, are converted to fat when the caloric intake exceeds the body's requirements, and sucrose causes tooth decay by promoting the formation of plaque that sticks to teeth. Q: Sucrose does not undergo reactions that are typical of aldehydes and ketones, therefore it is a nonreducing what? Choices: - wheat - juice - salt - sugar A:
sugar
Q: Answer the following question given this paragraph: percent of the Amazon rainforest was lost. Rates are higher in other tropical rainforests. What we are likely to notice on a day-to-day basis as a result of biodiversity loss is that food will be more difficult to produce, clean water will be more difficult to find, and the rate of development of new medicines will become slower, as we depend upon other species for much of these services. This increased loss of biodiversity is almost entirely a result of human activities as we destroy species' habitats, introduce disruptive species into ecosystems, hunt some species to extinction, continue to warm the planet with greenhouse gases, and influence nature in other ways. Slowing the loss of biodiversity is within our abilities if we make dramatic changes in our consumptive behavior and identify and protect the elements of our ecosystems that we depend on for our lives and welfare. Q: The result of what, in places like the amazon rainforest, is that food will be harder to produce, clean water will be harder to find, and development of new medicines will become slower? Choices: - environmnental loss - pollution loss - biological loss - biodiversity loss A:
A: biodiversity loss
Question: Answer the following question given this paragraph: Abiotic factors are the nonliving aspects of the environment. They include factors such as sunlight, soil, temperature, and water. Q: What are the nonliving aspects of the environment called? Choices: - metastatic factors - nucleic factors - antibiotic factors - abiotic factors A:
Answer: abiotic factors

Answer the following question given this paragraph: STIs may be caused by several different types of pathogens, including protozoa, insects, bacteria, and viruses. For example: Protozoa cause an STI called trichomoniasis. The pathogen infects the vagina in females and the urethra in males, causing symptoms such as burning and itching. Trichomoniasis is common in young people. Pubic lice, like the one in Figure below , are insect parasites that are transmitted sexually. They suck the blood of their host and irritate the skin in the pubic area. Q: Trichomoniasis is cause by what type of pathogen? Choices: - virus - bacteria - worm - protozoa A:
**Answer**
protozoa
