Blood is essential for many organisms, such as humans and animals, for its important function of transporting substances (food, oxygen), vitamins, waste (carbon dioxide), hormones, etc. to all tissues and cells of the body.
1) Blood volume
If the blood volume increases ==> the blood flow increases.
2) Viscosity of blood
If we have an increase in blood viscosity ==> we have a decrease in blood flow
3) Peripheral Resistance
If there is an increase in peripheral resistance ==> the blood flow decreases
4) Diameter of blood vessels
If we have an increase in diameter of
blood vessels ==> decreased peripheral resistance ==> increased blood flow
5) Blood pressure
If the blood pressure increases ==> the blood flow increases.
6) In case of diseases
In the case of atherosclerosis or acute coronary syndrome ==> blood flow decreases.
7) Physical excercises:
During physical exercises ==> the heart rate increases ==> the blood flow increases.
Answer: Positive charge of 1

Had to look for the missing options and here is my answer.
The one that gives the best description of the most common way how material is added to the continental shelf is this: "Deposition of continental <span>sediments". This deposition includes biological, physical, and even chemical processes that occurred in a span of time. Hope this helps.</span>
False. Strontium 90 has a half life of only 30 years, and as millions of years pass, about the time fossils have been around, most if not all of any strontium would have decayed.
