Which of the following most likely indicates that a chemical change has
happened?
A. A plate breaks when it falls to the floor.
B. There's a loud sound when a jet airplane starts its engines.
C. An icicle melts in the sun.
D. A can is crushed when it is stepped on.

Answers

Answer 1

Answer:

Option B

Explanation:

A plate breaking when falling to the floor would be a physical change, not chemical, as what the plate is created from would not change.

An icicle melting in the sun would be a physical change, as an icicle is frozen water, and after melting it would be normal water.

A can being crushed is still just a physical change, as the material making the can(typically aluminum) has not changed.

When a jet airplane starts its engines, fuel is combusted, creating energy for the engines to start. This would create the loud noise. As fuel is combusted, it turns into different things, henceforth the sound would imply a chemical change has occurred.

Mitochondria require glucose to convert ADP to ATP. Which of the following statements describes how ADP is converted into ATP?

A. ADP loses a phosphate group which stores energy for use by the cell.
B. ADP gains a phosphate group which stores energy for use by the cell.
C. ADP loses a phosphate group which releases energy for use by the cell.
D. ADP gains a phosphate group which releases energy for use by the cell.

Answers

Answer:

B. ADP gains a phosphate group which stores energy for use by the cell.

Explanation:

ADP is converted to ATP for the storing of energy by the addition of a high-energy phosphate group. The conversion takes place in the substance between the cell membrane and the nucleus, known as the cytoplasm, or in special energy-producing structures called mitochondria.

The statement that describes how ADP is converted into ATP is as follows:

ADP gains a phosphate group which stores energy for use by the cell.

Thus, the correct option is B.

What is ATP?

ATP stands for Adenosine triphosphate. It may be defined as an organic compound that delivers energy to operate many processes in living cells, such as condensate dissolution, muscle contraction, nerve impulse propagation, and chemical synthesis.

ATP is considered a high-energy compound that furnishes immediate energy to the cell for metabolic activities.

ADP gets converted into ATP by gaining one phosphate group which is the most potent high-energy phosphate. This conversion of ADP to ATP generally takes place in the cytoplasm or in the membrane-bound cell organelle known as mitochondria.

Therefore, the correct option for this question is B.

How is earths surface most likely to change as the water freezes and expands on a mountain side over time?

Erosion will cause the ice to crack the rock

Physical weathering will cause the ice to crack the rock

Chemical weathering will cause the water to dissolve the rock

Disposition will cause the water to break the rock into sediment

Answers

The earths surface most likely to change as the water freezes and expands on a mountain side over time because Physical weathering will cause the ice to crack the rock.

What is soil erosion?

Erosion is nothing more than the displacement of land that happens from one place to another. In nature, the erosive process occurs by the natural action of the sun, winds and, mainly, rainwater.

It is a natural procedure, however, human action contributes to its intensification. The uncontrolled erosion process causes great damage to the environment, as it acts on the wear of the soil, makes it difficult to maintain species of animals and plants, in addition to disrupting human activities.

In this case, Erosion involves the wearing down, transport and deposition of soils and rock particles. So, the Physical weathering will cause the ice to crack the rock.

Use scientific reasoning to explain why, in general, it makes sense that the lion population is taking longer to recover than the herbivore populations.

Answers

To scientifically answer the question using scientific reasoning, explaining generally why it makes sense that the lion population is taking longer to recover than the herbivore populations is that;

The herbivore populations have enough food in the ecosystem,this food is in the form of flora,and this food they get keep their energy flowing and also has a way of ensuring their high recovery rates.

Then looking at the lion population,on the contrary,they have to depend on feeding on smaller animals this is because the larger animals reproduce at a smaller pace, and lions with a smaller prey,lions don't get enough and adequate food/nutrition for themselves and also for their pride of lions,this ascertains the fact that lion population take a longer time to recover than it's counterparts which is the herbivores.

Answers

Answer: Andrew Jackson was a strong president. He used the office to forcefully pursue his agenda. This cartoon is quite famous, coming out around 1833, because of the 1833 removal order. In the cartoon, the president can be seen holding a veto in his hand, and standing on top of the Constitution. He is dressed up as a king, holding - perhaps - too much power. I believe that the intended audience was the people. The people saw him as a king, abusing his powers as a president. The author’s purpose was to show how people truly viewed him. The president’s order to remove federal deposits from the Bank of the United States led to an increase in state debt. The President was strongly criticized because he acted without congressional approval, as a king would.

He wanted to show that he was a man of the people but it was viewed as a person who was wielding too much power than was suitable for a president as he occasionally acted without congressional approval.
