Answer the following question given this paragraph: The amount of energy in molecules of matter determines the state of matter . Matter can exist in one of several different states, including a gas, liquid, or solid state. These different states of matter have different properties, which are illustrated in Figure below . Gasses have the most energy, and solids have the least energy. Q: What is determined by the amount of energy in molecules? Choices: - kingdom - radioactivity - momentum - state of matter A:
state of matter

Answer the following question given this paragraph: Active transport requires energy from the cell. It occurs when substances move from areas of lower to higher concentration or when very large molecules are transported. Types of active transport include ion pumps, such as the sodium-potassium pump, and vesicle transport, which includes endocytosis and exocytosis. Q: What occurs when substances move from areas of lower to higher concentration or when very large molecules are transported? Choices: - migration - diffusion - passive transport - active transport A:
(Answer)
active transport
Ques: 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:
Ans: solid, liquid, gas, and plasma
(Q).
Answer the following question given this paragraph: Fossils are preserved remains or traces of organisms that lived in the past. Most fossils form in sedimentary rock. Fossils can also be preserved in other ways. Fossilization is rare. It's very unlikely for any given organism to become a fossil. Q: What is the term for preserved remains or traces of organisms that lived in the past? Choices: - deposits - bones - remains - fossils A:
(A).
fossils
Ques:Answer the following question given this paragraph: Hydropower utilizes the energy of falling water. Q: Hydropower is generated with what natural resource? Choices: - light - air - fire - water A:

Ans:water
Ques:Answer the following question given this paragraph: 5.3 Active Transport The combined gradient that affects an ion includes its concentration gradient and its electrical gradient. A positive ion, for example, might tend to diffuse into a new area, down its concentration gradient, but if it is diffusing into an area of net positive charge, its diffusion will be hampered by its electrical gradient. When dealing with ions in aqueous solutions, a combination of the electrochemical and concentration gradients, rather than just the concentration gradient alone, must be considered. Living cells need certain substances that exist inside the cell in concentrations greater than they exist in the extracellular space. Moving substances up their electrochemical gradients requires energy from the cell. Active transport uses energy stored in ATP to fuel this transport. Active transport of small molecular-sized materials uses integral proteins in the cell membrane to move the materials: These proteins are analogous to pumps. Some pumps, which carry out primary active transport, couple directly with ATP to drive their action. In co-transport (or secondary active transport), energy from primary transport can be used to move another substance into the cell and up its concentration gradient. Q: The combined gradient that affects an ion includes its concentration gradient and its what? Choices: - radiation gradient - cell membrane - electron bond - electrical gradient A:

Ans:
electrical gradient
