Why does the oxidation of organic compounds by molecular oxygen to produce CO₂ and water release free energy? A) The covalent bonds in organic molecules and molecular oxygen have more kinetic energy than the covalent bonds in water and carbon dioxide. B) Electrons are being moved from atoms that have a lower affinity for electrons (such as C) to atoms with a higher affinity for electrons (such as O). C) The oxidation of organic compounds can be used to make ATP. D) The electrons have a higher potential energy when associated with water and CO₂ than they do in organic compounds. E) The covalent bond in O₂ is unstable and easily broken by electrons from organic molecules.

DNA plays a major role in heredity, composing the genes that are passed down from parent to offspring. It also plays a major role in the everyday workings of your cells. It does this by creating molecules, such as enzymes, that regulate cell functions. These enzymes belong to a larger class of molecules known as A) RNA. B) proteins. C) ion pumps. D) amino acids

What kind of air masses form over land? Maritime air mass Polar air mass Continental air mass Tropical air mass

Answers

The correct answers are:

- Polar air mass;

- Continental air mass;

The polar air masses form predominantly over land, or rather ice. They form over the poles and their close proximity, with the ones forming on the south pole being formed directly over Antarctica as a land mass, while the ones on the north pole being formed over ice, or rather the frozen ocean. They are very cold and very dry air masses.

The continental air masses form above land, deeper into the mainlands of the continents, which is why that have this name. They can be either very cold and dry in winter, or very hot and dry in the summer.

Answer:

Continental air mass

In which ways are RNA and DNA different?a. RNA has ribose sugar, DNA has deoxyribose sugar
b. RNA has uracil, DNA has thymine
c. RNA is single-stranded, DNA is a double-helix
d. all of the above

Answers

Answer:

d. all of the above is the correct answer.

Explanation:

These are the main difference between RNA and DNA

  • Sugar present in RNA is ribose sugar whereas sugar present in DNA is deoxyribose sugar.
  • Nitrogenous bases present in DNA are adenine, guanine, cytosine, and thymine whereas in the case of RNA nitrogenous bases present are adenine, guanine, cytosine and uracil which is replaced by thymine in DNA.
  • RNA is single-stranded whereas DNA is a double-helix.

thus the all the above(D) options are correct.

Final answer:

RNA and DNA differ in three major areas: the types of sugars they contain, the bases they use, and their structure. RNA contains ribose sugars and the base uracil, while being single-stranded. In contrast, DNA contains deoxyribose sugars, the base thymine, and has a double helical structure.

Explanation:

RNA and DNA, which can both be found in cells, have several significant differences. To answer your question, the correct choice would be (d) all of the above because:

  • RNA has ribose sugar, while DNA has deoxyribose sugar. The difference is that the deoxyribose sugar in DNA is missing one oxygen atom compared to the ribose sugar in RNA.
  • RNA contains the base uracil whereas DNA uses the base thymine. This change makes DNA more stable and less likely to mutate.
  • Finally, RNA is single-stranded and DNA is a double helix. The double-stranded DNA is more stable resulting in a reduction in damage and loss of genetic information.

Dissolution and precipitation of _______ are the main processes that form limestone caves? A. calcite
B. sandstone
C. clay
D. salt water

Answers

The answer is letter A. 
Dissolution and precipitation of calcite are the main processes that form limestone caves.

>Mineral precipitation from solution:Calcite dripstones form from calcite
saturated groundwater in cave.
> Limestones are produced from the mineral calcite (calcium carbonate) and sediment. The main source of limestone is the limy ooze formed in the ocean. They can be precipitated from ocean water or it can be formed from sea creatures that secrete lime such as algae and coral.

Dissolution and precipitation of _______ are the main processes that form limestone caves? The answer is, A. calcite

Name 3 things you've done that have shown initiative

Answers

Final answer:

The answer provides examples of personal behaviors influenced by circumstance, such as stepping up to lead a school project, initiating a neighborhood clean-up, or proposing a solution to a consistent problem at work.

Explanation:

This question pertains to personal experiences where your behavior was influenced by a situation. Since the question is asking for personal instances, hypothetical examples could be as follows:

  1. Project Leadership: One situation may be at a group project in school where no one was taking charge, and you stepped up to become the project leader. This initiated an organized structure and helped the group succeed.
  2. Community Service: Maybe there was a time that your local community park was full of litter, and you initiated a clean-up drive and encouraged your neighbors to participate.
  3. Problem-solving at work: Another example might be when you discovered a consistent issue at your part-time job and took the initiative to develop and propose a solution to your manager.
