Answer:

The correct order is shown in the attachment below.

Heart attack or myocardial infarction is a medical situation which occurs when there is a decrease in the flow of blood towards the heart.

It usually starts with the deposition of substances like fats, cholesterol, et cetera which leads to the formation of plaque in the artery (especially those which feed coronary arteries).

The plaque or blockage reduces the flow of blood towards the heart.

As a result, the heart starting contracting more vigorously which increases the blood pressure and thickens the cardiac muscles.

With time, the efficiency of the heart decreases due to which less oxygen is reached to the heart and ultimately, a person experiences a heart attack.

This is the correct sequence of steps in the development of heart failure.

1. Fat deposits build up along artery walls

2.Blockage in artery obstruct blood flow and can cause heart attacks

3.Blood pressure increases and cardiac muscles thicken

4.Heart pumps blood less efficiently

5.Oxygen delivery is reduced and heart failure occurs

Animals behave in order to satisfy ___ needs.

yanalaym [24]

Every animal, plant and human needs the primary physiological needs of water, food and shelter provided by the abiotic system.

Organisms in the ecosystem are interdependent. Ecosystem is encompassing all the life on earth in the physical environment that supports it. In addition, an ecosystem involves both the biological (plants, animals, human beings) and non-biological (land, water, soil, and atmosphere) community which interacts as a system. More importantly, the living things are very dependent on the abiotic community since it cannot survive by itself.

If a motion is not seconded, what happens to the motion?

AveGali [126]

Answer:

After a motion is proposed, if the motion requires a second and none is immediately offered, the chair of the body will usually ask, "Is there a second?" If no second is obtained within a few moments of proposing the motion, then the motion is not considered by the assembly, and is treated as though it was never offered. Such a motion may be introduced again at any later time.
