Which of these is a way to increase the availability of freshwater
Nastasia [14]

Answer:

Option A

Explanation:

Options -

A-avoid water pollution.

B-build thermal power plants.

C-add water features to gardens.

D-avoid drip irrigation systems

Solution -

The largest source of freshwater on planet earth is underground water. The water beneath the surface of earth is very limited. The total fresh water reserve on earth is 3% of the total water on earth. Pollution due to discharge of waste water into the rivers and oceans has caused the degradation of not only surface water but also ground water.  

Thus, option A is correct

Drip irrigation is a means to prevent wastage of water during irrigation. Thus, avoiding it will cause further loss of fresh water.  

Addition of water feature will increase usage of water, thus it is also incorrect

Building thermal plant will also cause water pollution and wastage. Hence, option  B is also incorrect

In arteriosclerosis, overproduction of abnormal collagen and decreased quantities of elastin lead to what?
Tcecarenko [31]

In arteriosclerosis, overproduction of abnormal collagen and decreased quantities of elastin lead to Decreased coronary artery perfusion.

Arteriosclerosis is a condition in which the arteries, which transport oxygen and nutrients from the heart to the rest of the body, thicken and stiffen, often limiting blood flow to the organs and tissues. Flexible and elastic arteries indicate good health. However, the artery walls can stiffen over time, a phenomenon known as arterial hardening.

The accumulation of lipids, cholesterol, and other chemicals in and on the artery walls is known as atherosclerosis. The accumulation is known as plaque. Atherosclerosis can constrict the arteries and obstruct blood flow. The plaque may rupture and cause a blood clot.

Symptoms of arteriosclerosis:

  • chest pressure or discomfort (angina)
  • sudden numbness or weakness in the arms or legs.
  • speech slurs or speaking difficulties.
  • vision briefly lost in one eye.
  • weakened facial muscles
  • ache while walking.
  • elevated blood pressure
  • renal failure

dmitriy555 [2]

Answer:

<h3>The Prokaryotic Cell</h3>

Prokaryotes are unicellular organisms that lack organelles or other internal membrane-bound structures. Therefore, they do not have a nucleus, but, instead, generally have a single chromosome: a piece of circular, double-stranded DNA located in an area of the cell called the nucleoid.
