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
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.

Nitrogen dioxide is released into the atmosphere by the burning of fossil fuels.
Gases released from volcanic eruptions.
The release of gases from decaying vegetation.
Radon released from the natural breakdown of uranium in rocks and soils.
Answer: A,B,C,D
Explanation:USAtestprep
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.

Please answer the questions below. Point values are listed in parentheses.
In a simple ecosystem, there are two primary producers: species A and species B. Species A is eaten by species C and species D. Species E eats species B. And Species F eats E and D.
a. Please draw this food web.
b. Name a species in each trophic level
i. First trophic level
ii. Second trophic level
iii. Third trophic level
c. Name a secondary consumer in your food web.
Answer:
Lion.
Explanation:
Species A and B are the plants which are eaten by the primary consumer is called herbivore such as rabbit, zebra and deer. The specie C, D and E are the primary consumer which belongs to second trophic level. The specie F feeds on specie E and D so it is called carnivores and belongs to third trophic level. In the food web, Specie C is rabbit, specie D is zebra and specie E is deer. Lion is the specie F which feeds on both zebra and deer. The name of secondary consumer in the food web is lion.
What is the general shape of the graph?
Cell division gizmo
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.

How do Taxol and Nocodazole affect microtubules, and subsequently the developing organism?
Answer:
Taxol induces the assembly of microtubules, while Nocodazole suppresses tubulin assembly
Explanation:
Taxol and nocodazole are antimitotic drugs, i.e., drugs that inhibit the progression through the cell cycle, which is useful for killing cancer cells. Microtubules are proteins that act as the 'skeleton of the cell', which need to be reorganized when cells replicate. These structures (microtubules) are composed of α and β-tubulin heterodimers which assemble into protofilaments of microtubules. Taxol is an antimitotic drug that induces the formation of microtubules, thereby inhibiting microtubules' reorganization during mitosis. In consequence, cells treated with Taxol enter into apoptosis (i.e., programmed cell death). Moreover, Nocodazole is known to induce microtubule disassembly by interfering with the polymerization of tubulin monomers. In consequence, Nocodazole is useful to depolymerize the microtubule cytoskeleton.

which product of the electron transport chain reenters the krebs cycle?
A. ATP
B. CoA
C. NAD+
D. NADH
E. pyruvate
Answer:
C. NAD+
Explanation:
PLATO
The Krebs Cycle requires NAD+ and FAD+ from the electron transport chain and operates thanks to several different enzymes that completely oxidize Acetyl-CoA.
Aerobic respiration takes place in two stages: the Krebs cycle and electron transport and oxidative phosphorylation (these last two processes occur in a coupled manner).
The Krebs cycle takes place in the mitochondria and allows carbohydrates, lipids and amino acids to be completely oxidized, producing a large amount of metabolic energy.For the cycle to begin, it needs to acetyl-CoA, coming from the degradation of more complex molecules, to give rise to citric acid.In the electron transport chain each molecule of NADH becomes 3 ATP (2 NADH x 3 = 6 ATP).The conversion of pyruvic acid to AcetylCoA in the mitochondrial matrix yields 2 NADH for each glucose molecule. (2 NADH x 3 ATP = 6 ATP).Two molecules of acetyl-CoA enter the Krebs cycle and give two of GTP and 6 NADH and 2 FADH2.Therefore, we can conclude that the Krebs Cycle is a fundamental process that occurs in the matrix of cellular mitochondria, and that it consists of the release of the chemical energy contained in Acetyl-CoA.

how is hydro electricity produced step by step explanation
Answer:
ydropower, electricity produced from generators driven by turbines that convert the potential energy of falling or fast-flowing water into mechanical energy
Explanation:
In the generation of hydroelectric power, water is collected or stored at a higher elevation and led downward through large pipes or tunnels (penstocks) to a lower elevation; the difference in these two elevations is known as the head. At the end of its passage down the pipes, the falling water causes turbines to rotate. The turbines in turn drive generators, which convert the turbines’ mechanical energy into electricity. Transformers are then used to convert the alternating voltage suitable for the generators to a higher voltage suitable for long-distance transmission. The structure that houses the turbines and generators, and into which the pipes or penstocks feed, is called the powerhouse.
