Answer:
Ideally, the experimental and control groups are identical. As much as possible, the two groups should overlap in every characteristic.
Explanation:
At the beginning of your study, you need your two groups to be as statistically similar as is humanly possible. That way, when you control for other variables, you can reasonably attribute any statistically significant differences at the end of the study to your intervention.
Answer:
out of
into
Explanation:
As pressure exerts force, Hydrostatic pressure is a type of force that occurs in fluid e.g (interstitial fluids) on the walls of the capillary. The helps to carry fluid-like materials out of the tissue capillary. There are quite bunch of relative factors affecting the hydrostatic pressure which include; the liquid density and distance beneath the liquid surface,force of gravity.
On the other hand, The protein osmotic pressure difference between capillary fluid and interstitial fluid normally favors movement of fluid into a tissue capillary. This protein substances consist of albumin, plasma protein etc. From our knowledge of osmosis as well, we knew it is the movement of substances through a semi-permeable membrane from the region of higher concentration to a lower concentration. Therefore the protein osmotic pressure bring about movement of fluid like substances into the tissue capillary.
