Answer:

C. Coal

Explanation:

Coal is a fossil fuel that develops from remains of ancient organisms. Death of plants and their subsequent burying in ground initiates the process of coal formation. Anaerobic conditions do not allow the bacteria and fungi to decompose the wood completely. The buildup of heat and pressure on partially decomposed wood converts them into coal over a long period of time. Since coal formation is a slow natural process, it is a non-renewable energy source with limited supply.

Answer:

you would use your muscles from your legs and your body to get up from your bed and go to your fridge, your muscular system helps you up by being a structure for the muscles to apply force, you will use arm muscles for getting out cookies and milk. Then you will drink and eat your cookies and milk with your jaw muscle and send it down your esophagus to the intestines for the digestive system to break down your food. Then you will use your legs(muscles) to go back to your bed and sleep.

What is microgravity, and what causes it?

fgiga [73]

Answer:

The answer is because they are in free fall. In a vacuum, gravity causes all objects to fall at the same rate. The mass of the object does not matter. If a person drops a hammer and a feather, air will make the feather fall more slowly. But if there were no air, they would fall at the same acceleration.

Biological polymers are produced by the process of __________, also known as __________. Choose two answers to fill in the blank

telo118 [61]

Complete question:

Biological polymers are produced by the process of __________, also known as __________. Choose two answers to fill in the blanks.

dehydration synthesis
condensation reactions
hydrolysis reactions
decomposition reactions
hydrogenation reactions

Answer:

Biological polymers are produced by the process of dehydration synthesis, also known as condensation reactions.

Explanation:

The process of monomers union is known as Dehydration synthesis/condensation reactions. It refers to the formation of a polymer, by the union of many monomers, which also implicate <u>losing a water molecule</u> and using energy to occur. Every monomer has a free H atom and a hydroxyl group (-OH) in the extremes. When two monomers get together, the H atom and the -OH join to form a water molecule, which is released. The result is a polymer of two monomers and H₂O.

The opposite process is known as hydrolysis, which occurs when the polymer hydrates and releases monomers.
