Explanation:
Answer: The answer is option B. Cell Walls
Explanation: Prokaryotic cells are much smaller than eukaryotic cells, have no nucleus, and lack organelles. All prokaryotic cells are encased by a cell wall. In eukaryotes, vertebrates don't have a cell wall but plants do.
The most useful microscope to use would be a Compound Light Microscope. These microscopes are limited to about a good 2000X magnification. Not only can you use this to estimate the number of red blood cells, but it is good for seeing and identifying protozoa, bacteria, and organism cells.
Answer:
The ability of caffeine to inhibit adenosine receptors, plays a very important role in heightened alertness and sleeplessness.
Explanation:
"<em><u>Caffeine</u></em>" (<em>1,3,7-trimethylxanthine</em>) is an alkaloid obtained from plants. It has a chemical formula of C8H10N4O2.
Caffeine is generally <em>hydrophillic</em> but sufficiently <em>lipophilic</em> to pass through all biological membranes and readily cross the blood-brain barrier.
Therefore can bind with the adenosine receptors. Due to the blocking of adenosine inhibitory effects through its receptors held by paraxanthine and caffeine, it indirectly affects the release of <u>norepinephrine, dopamine, acetylcholine, serotonin, glutamate</u> e.t.c.
The release of the above-mentioned hormones have a great impact on the heightened alertness of the body, especially <em>dopamine</em> and <em>serotonin</em>.
When newly formed proteins leave the rough endoplasmic reticulum, they are transported to this organelle, where the proteins are sorted and packaged. Golgi apparatus. This part of the cell manufactures the ribosomal subunits.
Golgi apparatus
IF THAT DOESNT WORK THEN USE
Rough Endoplasmic Reticulum
