Explain how the generation of electricity by hydroelectric, tidal
sveta [45]

Hydroelectric, tidal and wind sources are similar in the sense that are all renewable sources of electricity generation.

<h3>Generation of electricity</h3>

Electricity is generated in many ways. Some of the ways are renewable while some of the ways are non renewable. The renewable means of generation can be reused while the non renewable can not be reused.

Now,  hydroelectric, tidal and wind sources are similar in the sense that are all renewable sources of electricity generation.

What are glaciers? A glacier is a huge mass of ice that moves slowly over land.
tigry1 [53]

Answer:

What do they look like?

Glaciers look like solid blocks of ice.

What climate do they exist in?

Regions that have high snowfall in winter and cool temperatures in summer.

Where can you find them?

Most of the world's glacial ice is found in Antarctica and Greenland, but glaciers are found on nearly every continent, even Africa.

What do you think we can learn from glaciers?

Glaciers preserve bits of atmosphere from thousands of years ago in these tiny air bubbles, or, deeper within the core, trapped within the ice itself. This is one way scientists know that there have been several Ice Ages. Scientists are also finding that glaciers reveal clues about global warming.

(The last question is unclear to me, so I'm going to take a guess as to what you meant)

Why is sea ice so important?

Arctic sea ice keeps the polar regions cool and helps moderate global climate.

I hope this helps!! :3

Angiotensin-converting enzyme (ACE) inhibitors and other vasodilators are used in the early treatment of heart failure. They act
Iteru [2.4K]

Answer:

Option c. cause pooling of the blood and decreased venous return to the heart

Explanation:

The ACE inhibitors increases the diameter of the blood vessels (vasodilation) that improves the flow of blood. This reduces the work load on the heart. At the time of heart failure, a substance called angiotensin is released. This angiotensin formation is blocked by the ACE inhibitors. Angiotensin is involved in narrowing the blood vessels.

The ACE cause pooling of the blood and decreased venous return to the heart. The ACE inhibitors causes vasodilation that allows decrease in blood pressure. So, there is no increase in arterial pressure, aldosterone and loss of volume. Thus, option C is correct.
