It stands for per rectum
It works according to the guidelines set by the authorities
Answer:
Diffusion is the net movement of any substance from a higher concentration region to the lower concentration region. It is conducting by a concentration gradient.
Osmosis is a process in which solvent (molecules) pass through a semipermeable membrane (SPM) from a lower concentration solution region to a higher concentration region so it equalizes the concentrations on each side of the SPM.
A <u>hypotonic solution</u> is a solution that has a higher concentration of solutes inside the cell than outside of the cell. Thus the movement of water is from outside to the inside of the cell.
A <u>hypertonic solution</u> is a solution in which solutes concentration is greater outside the cell and low concentration inside. The movement of water is from inside the cell to outside the cell.
An <u>isotonic solution</u> where two solutions having the same concentration inside and outside of the cell so there is free movement of molecules across a semipermeable membrane.
What your brain says about the object's distance is Nothing - this is a visual pattern recognition test, not distance. The size of the object and the distance it is from the observer determine the size of the image that forms on the retina.
- Nothing - this is a visual pattern recognition test, not distance.
<h3>How does the image arrive on the retina?</h3>
After the pupil, the image reaches the lens and is focused on the retina. The eye's lens produces an inverted image, and the brain converts it to the correct position. In the retina, more than one hundred million photoreceptor cells transform light waves into electrochemical impulses, which are decoded by the brain.
With this information, we can conclude that The size of the object and the distance it is from the observer determine the size of the image that forms on the retina.

Heyo!
I believe the answer is..

Answer:
The correct answer is A. The cell membrane is both hydrophilic and hydrophobic due to the presence of phospholipid.
Explanation:
98% of the lipids present in cell membranes are amphipathic, that is, they have a hydrophilic end (which has affinity and interacts with water) and a hydrophobic end (which repels water). The three main types of lipids in eukaryotic membranes are phospholipids, sphingoglucolipids and steroids (especially cholesterol); It is worth mentioning that phosphoglycerides and sphingolipids are found in all cells. The latter, glycolipids and steroids, do not exist or are scarce in the plasma membranes of prokaryotic cells, fungi and some protists. There are also neutral fats, which are non-amphipathic lipids, but only represent 2% of the total membrane lipids.
