Question: Q: What element is a biochemical compound based on? Read this paragraph and choose the correct option from the provided answers: Besides water, most of the compounds in living things are biochemical compounds. A biochemical compound is a carbon-based compound that is found in living organisms. Carbon is an element that has a tremendous ability to form large compounds. Each atom of carbon can form four chemical bonds with other atoms. A chemical bond is the sharing of electrons between atoms. Bonds hold the atoms together in chemical compounds. A carbon atom can form bonds with other carbon atoms or with atoms of other elements. Choices: - hydrogen - nitrogen - oxygen - carbon A:
Answer: carbon

Q: What can be used to accelerate the rate at which chemical reactions occur? Read this paragraph and choose the correct option from the provided answers: Enzymes increase the rate of chemical reactions by reducing the amount of activation energy needed for reactants to start reacting. One way this can happen is modeled in the Figure below . Enzymes aren't changed or used up in the reactions they catalyze, so they can be used to speed up the same reaction over and over again. Each enzyme is highly specific for the particular reaction is catalyzes, so enzymes are very effective. A reaction that would take many years to occur without its enzyme might occur in a split second with the enzyme. Enzymes are also very efficient, so waste products rarely form. Choices: - hormones - protein - components - enzymes A:
**Answer**
enzymes

Q: What type of energy causes erosion at the shore? Read this paragraph and choose the correct option from the provided answers: Wave energy does the work of erosion at the shore. Waves erode sediments from cliffs and shorelines. The sediment in ocean water acts like sandpaper. Over time, they erode the shore. The bigger the waves are and the more sediment they carry, the more erosion they cause ( Figure below ). Choices: - tidal - potential - kinetic - wave A:
wave
