Answer the following question given this paragraph: Proteins in the diet are necessary for life. Dietary proteins are broken down into their component amino acids when food is digested. Cells can then use the components to build new proteins. Humans are able to synthesize all but eight of the twenty common amino acids. These eight amino acids, called essential amino acids , must be consumed in foods. Like dietary carbohydrates and lipids, dietary proteins can also be broken down to provide cells with energy. Q: Dietary proteins are broken down into amino acids during what process? Choices: - accumulation - filtration - photosynthesis - digestion A:
digestion
Answer the following question given this paragraph: The level of biodiversity found in the fossil record suggests that the last few million years include the period of greatest biodiversity in the Earth's history. However, not all scientists support this view, since there is a lot of uncertainty as to how strongly the fossil record is biased by the greater availability and preservation of more recent fossil-containing rock layers. Some researchers argue that modern biodiversity is not much different from biodiversity 300 million years ago. Estimates of the present global species diversity vary from 5 million to 30 million species, with a best estimate of somewhere near 10 million species. All living organisms are classified into one of the six kingdoms: Archaebacteria (Archaea), Eubacteria (Bacteria), Protista (Protists), Fungi, Plantae (Plants), and Animalia (Animals). Q: All living organisms are classified into one of six broad categories called what? Choices: - cities - tribes - nobles - kingdoms A:
kingdoms
Q: Answer the following question given this paragraph: Q: What facilitates the diffusion of ions across a membrane? Choices: - photon channels - ionic bonds - passive transport - ion channels A:
A: ion channels
Question: Answer the following question given this paragraph: An underground layer of rock that is saturated with groundwater is called an aquifer . A diagram of an aquifer is pictured below ( Figure below ). Aquifers are generally found in porous rock, such as sandstone. Water infiltrates the aquifer from the surface. The water that enters the aquifer is called recharge . Q: What is the name for an underground layer of rock that is saturated with groundwater? Choices: - gradient - aqueous cavity - artesian well - aquifer A:
Answer: aquifer

Answer the following question given this paragraph: Many chemical equations also include phase labels for the substances: (s) for solid, () for liquid, (g) for gas, and (aq) for aqueous (i. , dissolved in water). Special conditions, such as temperature, may also be listed above the arrow. For example, 2NaHCO. Q: Phase labels - and even special conditions - are sometimes included for the substances that are part of what? Choices: - solid equations - toxic equations - carbon equations - chemical equations A:
**Answer**
chemical equations

Answer the following question given this paragraph: Another example of a behavior with a yearly cycle is migration . Migration is the movement of animals from one place to another. Migration is an innate behavior that is triggered by changes in the environment. For example, animals may migrate when the days get shorter in the fall. Migration is most common in birds, fish, and insects. In the Northern Hemisphere, many species of birds, including robins and geese, travel south for the winter. They migrate to areas where it is warmer and where there is more food. They return north in the spring. A flock of migrating geese is pictured below ( Figure below ). Q: What is the movement of animals from one place to another? Choices: - communication - trade - population - migration A:
**Answer**
migration
