Continental polar air mass this is the type of mass that come from northern Canada
Answer: C. The red blood cells released water through osmosis. The release of water helped the blood cells keep a similar concentration of solutes as the outside solution.
Explanation:
Osmosis is a process whereby water molecules move from an area where they are in higher concentration than a solute to an area where they are in lower concentration. They do this by moving through a selectively-permeable membrane.
With sugar added to the solution, the water in the red blood cells will have a higher concentration of water in the cells than the solution so water molecules will move from the cell - through the cell membrane - to the solution. They will keep doing so till the concentration of solutes are more or less similar in both the cells and the solution.
Mechanisms that regulate smooth muscle contraction (independently of nerves or hormones) by which organs and tissues alter their own arteriolar resistances and blood flow are referred to as : Myosin and actin
<h3>Meaning of Myosin and actin </h3>
Myosin and actin are proteins that are found in all type of muscle tissue.
Smooth muscles (Heart) do not need nerves but it is an involuntary action, due to the presence of the myosin and actin, it work continuously.
Myosin and Actin are like a sliding filament in the muscle structure of the heart. they cause the heart to work continuously.
in conclusion, the Mechanisms that regulate smooth muscle contraction (independently of nerves or hormones) by which organs and tissues alter their own arteriolar resistances and blood flow are referred to as : Myosin and actin
