Answer:

the rhythm of heart contractions.

Explanation:

In Human anatomy, cardiac cycle can be defined as a complete heartbeat of the human heart which comprises of sequential alternating contraction and relaxation of the atria and ventricles, therefore causing blood to flow unidirectionally (one direction) throughout the human body.

Generally, the cardiac cycle occurs in two (2) stages;

1. Diastole : in this stage, the ventricles is relaxed and would be filled with blood.

2. Systole: at this stage, the muscles contracts and thus, allow blood to be pushed through the atria.

An electrocardiogram (ECG) provides information about the rhythm of heart contractions.

Additionally, the right atrioventricular valve (AV) also referred to as the tricuspid valve is located on the right dorsal side of the human heart. The right atrioventricular valve (AV) comprises of three (3) leaflets (flaps) which opens and closes in order to allow for the flow of blood from the right atrium of the human heart to the right ventricle. Also, the right atrioventricular valve is saddled with the responsibility of preventing blood from flowing backward in the mammalian heart.

The height of wind formed waves depends on what three things?
Ganezh [65]
The height wind waves or waves generated by the wind are surface waves that occur on the surface of oceans, lakes, rivers, seas and canals etc. Waves can travel thousands of miles before reaching land. They range in size from small ripples to over 100 foot high. They are dependent on the following three things:
1. Wind speed - the height of waves is dependent on the speed of the wind. The faster the wind, the higher the waves and vice versa. 2. Wind direction - the height of waves is dependent on  whether the wind is blowing offshore or onshore. Offshore winds blow from the land onto the sea so tend to cause bigger waves3. Storm winds in a cyclone or hurricane. These winds travel in circles around the eye of the storm and are usually very high in intensity. Depending on the intensity of the wind and the speed at which the wind is travelling, the wave height will differ.

What is biological magnification and how does it relate to the health warnings given to pregnant women about the consumption of
Anton [14]

Answer:

Biological magnification refers to a phenomenon where some of the substances like heavy metals or pesticides move up the food chain, make their way into the lakes or rivers, and are eventually consumed by aquatic species like fish. This, in turn, is further consumed by large species like large birds, humans or animals.  

This is associated with the health warnings given to pregnant women as too much eating of some kind of fish may influence the immune systems, that is, may affect the health of women who are pregnant.
