Answer the following question given this paragraph: Q: Ecologists already use the abilities of many prokaryotes to carry out bioremediation of soils and what else? Choices: - air - gas - plasma - water A:
water
Answer the following question given this paragraph: Bicarbonate Bicarbonate is the second most abundant anion in the blood. Its principal function is to maintain your body's acid-base balance by being part of buffer systems. This role will be discussed in a different section. Bicarbonate ions result from a chemical reaction that starts with carbon dioxide (CO2) and water, two molecules that are produced at the end of aerobic metabolism. Only a small amount of CO2 can be dissolved in body fluids. Thus, over 90 percent of the CO2 is converted into bicarbonate ions, HCO3, through the following reactions:. Q: Bicarbonate is the second most abundant anion in the blood. its principal function is to maintain your body's acid-base balance by being part of these? Choices: - curb systems - stream systems - compound systems - buffer systems A:
buffer systems
Q: Answer the following question given this paragraph: The photo above represents water in three common states of matter. States of matter are different phases in which any given type of matter can exist. There are actually four well-known states of matter: solid, liquid, gas, and plasma. Plasma isn't represented in the iceberg photo, but the other three states of matter are. The iceberg itself consists of water in the solid state, and the lake consists of water in the liquid state. Q: What are the four well-known states of matter? Choices: - solid, liquid, gas, and wave - solid, liquid, plasma, and metal - solid , imine , gas , and plasma - solid, liquid, gas, and plasma A:
A: solid, liquid, gas, and plasma
Question: Answer the following question given this paragraph: The locations where electrons are likely to be located around the nucleus are known as orbitals. Each orbital represents a three-dimensional region in which a given electron is most likely to be found. Q: What do we call the locations where electrons are likely to be located around the nucleus? Choices: - isotopes - cores - radials - orbitals A:
Answer: orbitals

Answer the following question given this paragraph: Primates have five digits (fingers or toes) on each extremity. Unlike the hooves of horses or the paddles of whales, the digits of primates are relatively unspecialized. Therefore, they can be used to do a variety of tasks, including grasping branches and holding tools. Q: How many digits do primates have on each extremity? Choices: - ten - four - three - five A:
**Answer**
five
(Q).
Answer the following question given this paragraph: Average speed is the total distance traveled divided by the elapsed time. (Average speed is not the magnitude of the average velocity. ) Speed is a scalar quantity; it has no direction associated with it. Q: Defined as total distance traveled divided by elapsed speed, average speed is a scalar quantity that does not include what? Choices: - shift - pressure - size - direction A:
(A).
direction
