Answer:

The correct answer is - Cholinergic antagonists.

Explanation:

The cholinergic antagonist is a class of medication that is general terms of agents that bind with choline receptors such as nicotinic and muscarinic that inhibit the effect of acetylcholine and another agonist.

It is a class of drugs that mimics, inhibit, or enhance the action of the neurotransmitter ACh which is the very first transmitter of nerve impulse within PNS that includes the region of ANS that regulates contraction of smooth muscle, such as upper respiratory tract.

Thus, the correct answer is - Cholinergic antagonist.

What evidence do the positions of the peaks and dips in its spectrum provide about an object? A. expansion B. elemental composit
Andreas93 [3]

Given what we know about the use of spectrums, we can confirm that the positions of peaks and dips provide information as to the elemental composition of the object in question.

The question asks about the dips and peaks of a spectrum, which allows us to assume we are dealing with Infrared spectroscopy and IR spectrums. This is defined as the measurement of how certain matter interacts with infrared radiation.

These graphs are used to measure how this matter absorbs, reflects, or even emits said radiation. Therefore, the use of spectrums allows us to infer as to the chemicals present or functional groups of an object, and therefore its elemental composition.

When looking at the spectrum graph, we will see that at times the curve dips down, which indicates that <u><em>less light </em></u>is transmitted. That means light is being absorbed. Due to the fact that bonds absorb different frequencies of light, <u>the </u><u>peaks </u><u>tell you what kinds of </u><u>bonds </u><u>are present from which we can identify the </u><u>elemental composition</u><u>.</u>

What would most likely happen to this ecosystem if all of the gray wolves were removed?
Vinil7 [7]

Answer:

D. The fox population would decrease

Explanation:

The food web shows that the gray wolves population are the only population that prey on the moose population. If the gray wolves were removed, the population of moose would increase significantly and would dominate the ecosystem. This means that other herbivores won't be able to compete with the moose population for the forages and vegetation in the ecosystem. The population of the other primary consumers/herbivores will reduce also. By implication, the fox which depend on other smaller preys to feed on would not have much prey to feed on. The ultimate effect of the removal of the gray wolves would lead to a later decrease in the population of the fox

Answer:

I think water does follow the law of conservation because water gets heavy every time like a Hurricane or a Tsumani they're both made out of the water and they do a lot of damage like Hurricane Delta was the record-tying fourth named storm of 2020 to strike Louisiana, as well as the record-breaking tenth named storm to strike the United States in that year. The twenty-sixth tropical cyclone, twenty-fifth named storm, ninth hurricane, and a third major hurricane of the record-breaking 2020 and A tsunami is a series of waves in a water body caused by the displacement of a large volume of water

Which type of energy does falling water striking a turbine produce?
Gemiola [76]
<span>The impulse turbine generally uses the velocity of the water to move the runner and discharges to atmospheric pressure. The water stream hits each bucket on the runner. There is no suction on the down side of the turbine, and the water flows out the bottom of the turbine housing after hitting the runner. An impulse turbine is generally suitable for high head, low flow applications.</span>
