In Kevin’s favorite comic book, the superhero has special powers. In one adventure, the superhero must stop an evil villain who threatens to destroy the city with a powerful energy blast.

As he confronts the villain, he makes the following claims:
1: “I can create an energy force field to save the city.”
2: “I can destroy the energy before it destroys the city.”
3: “I can convert all the energy before it can do any harm to the city.”
4: “I can absorb all the energy and make it go away.”

If the superhero must obey the law of conservation of energy, which of the above can he actually do?

a. 1

b. 2

c. 3

d. 4

Answers

Answer 1

Answer:

3

Explanation:

The law of conservation of energy states that energy cannot just be created, so answer one is out. Energy also cannot be simply destroyed, so answer to is out as well. From here it gets tricky, since both answers make some sense under these rules. However, absorbed is bassically the same as destroying it leaving only answer three. Answer three does obey these laws, as energy can be converted.

Why are rock samples from the Great Plains and from the Rocky Mountains composed of such similar minerals, when they look so different and come from different areas?

Answers

Answer:

The rock of the Great Plains is called sedimentary rock and the rock of the Rocky Mountains is called a igneous rock.  A Sedimentary rock: is a type of rock that is formed by the buildup of mineral/organic particles at Earth's surface. And an Igneous rock: a type of rock that forms when magma (molten rock) cools/crystallizes. Since they formed in different ways they must not have formed together. Rocks can form in different ways, shapes sizes etc.. This causes them to be different types.

Explanation:

1) Sedimentary rock: type of rock that is formed by the accumulation or buildup of mineral or organic particles at Earth's surface.

2) Igneous rock: type of rock that forms when magma (molten rock) cools and crystallizes.

The North American Plate, on which both the Great Plains and the Rocky Mountains are situated, is a common tectonic plate.

What is rock?

Rock is defined as a grouping of solid mineral grains that have grown or been cemented together. There are big rocks and little rocks. Rocks are created in the earth's crust. According to geology, rocks are produced when a combination of one or more minerals occurs. The sediments will eventually accumulate to such a high density that they will effectively turn into rock.

Although the Rocky Mountains' rock is volcanic and the Great Plains' rock is sedimentary, the two rock formations are stated to be different even though they contain comparable concentrations of specific minerals. Despite this, the two rocks have different formation processes.

Thus, the North American Plate, on which both the Great Plains and the Rocky Mountains are situated, is a common tectonic plate.

What is the name of the chemical that builds up in muscles during strenuous exercise when the body conducts anaerobic respiration?

Answers

Anaerobic respiration is an organism's ability to create energy in the form of Adenosine Triphosphate (ATP) without the use of oxygen. Sulfate, nitrate, or sulfur are employed instead. To simplify the preceding equation, organisms that employ anaerobic respiration to generate energy begin with glucose. Glucose is a type of sugar, and it is the same sugar as in the photosynthesis equation.

Organisms use glucose to make ethanol or lactic acid, CO2, and ATP.

When oxygen is scarce, people and animals employ anaerobic respiration for short periods. Imagine a runner on a track. It takes a few seconds for the extra oxygen they require to get into their muscle cells, therefore aerobic respiration takes a long to start.

Anaerobic respiration is needed to produce ATP during this brief period. In contrast to aerobic respiration, which produces 36 molecules of ATP per molecule of glucose, this mode of respiration produces only 2. Anaerobic respiration can potentially be harmful due to its by-products. Anaerobic respiration produces lactic acid in most people and animals.

It is poisonous to cells and causes a burning sensation in muscles when they weary. Thankfully, anaerobic respiration lasts only 20 seconds before aerobic respiration takes over.

Lactic acid buildup causes oxygen debt. For example, a sprinter is said to need a minute to catch his breath. More oxygen is required to break down lactic acid so it is no longer toxic to the cell.
The name of the chemical that builds up in muscles during strenuous exercise when the body conducts anaerobic respiration is lactic acid.
