The carbon that plants need for photosynthesis comes from (carbon dioxide gas in the atmosphere)
The name for the simplest sugar that is in our blood is glucose. There are many other kinds as they become more complex. Monosacchrides include glucose and fructose (from fruit), and then there are disacchrides such as table sugar and lactose (milk sugar).
D) no change in cardiac output, increased heart rate, decreased stroke volume occurs after blood donation
Explanation:
When a person donates blood, there is a slight loss of blood volume or hypovolemia. This triggers the baroreceptors of the blood; although does not trigger the osmoreceptor.
The baroreceptor responses are according to the arterial pressure which rises momentarily and results in increased sympathetic activity with decreased vagal activity.
These changes will lead to vasoconstriction, reduced stroke volume, increased heart rate or tachycardia which helps to maintain the cardiac output.
The soreness at the venepuncture site on the skin is due to bruising which is common after any needleprick. applying cold pack, elevating and resting the arm.
In order to compensate for the fluid volume loss and avoid dehydration, one must take plenty of fluids before and after blood donation.
A. The surface area to volume ratio increases
