What is the general shape of the graph?
Cell division gizmo

Answers

Answer and Explanation:

The image attached below presents the general shape of a graph showing cell division. This is because this graph shows the diversification of the amount of DNA in a cell in relation to the time and phases of cell division.

Through the graph shown below, we can see that before cell division, the cell passes through the G1 phase, where it has a specific amount of DNA for a cell in that cell stage. During phase S there is a progressive increase in the amount of DNA, and at the end of that phase, the cell will have twice as much DNA as it had before. The end of phase S, starts phase G2, where the amount of DNA is stabilized, until cell division occurs (represented in the graph by the letter M). Cell division causes a progressive decrease in the amount of DNA, which returns to the amount shown in phase G1.

Which of the following is an example of the endocrine system maintaining homeostasis? (3 points)
Detecting a pain stimulus and sending a signal to the spinal cord to perform an automatic response
Discharging an excessive amount of hormones in the blood and not sending a signal to stop production
Sending a message to the pituitary gland to start producing a hormone when the levels in the body are too low
Using sense organs to get information about the outside world and direct an appropriate body response release

Answers

Answer:

C. Sending a message to the pituitary gland to start producing a hormone when the levels in the body are too low

Explanation:

It's not A, because that's the nervous system, not endocrine.

It's not B, because homeostasis = balance, and not stopping production isn't balance

It's not D, because that's the nervous system again.

The endocrine system governs hormones.

All of the possible sources of acid rain are Sulfur dioxide is released into the atmosphere by the burning of fossil fuels; gases are released from volcanic eruptions; and nitrogen dioxide is released into the atmosphere by the burning of fossil fuels, so all the first, second, third, and fourth options are correct.

What is acid rain?

Acid rain is a type of rain that has a lower pH level than normal rainwater and occurs when emissions of sulfur dioxide (SO₂) and nitrogen oxides (NOx) react with atmospheric moisture to form sulfuric acid (H₂SO₄) and nitric acid (HNO₃). Acid rain can have harmful effects on the environment, including damaging forests, lakes, and aquatic life, and the primary sources of sulfur dioxide and nitrogen oxides are the burning of fossil fuels, such as coal and oil, in power plants, factories, and vehicles.

Hence, all the first, second, third, and fourth options are correct about the acid rain.
