Answer;
-Botulin
Explanation;
Botox injections smooth facial wrinkles because botulin is an ACh antagonist that blocks the underlying facial muscles.
-Botox injections are the best known of a group of medications that use various forms of botulinum toxin to temporarily paralyze muscle activity. This toxin is produced by the microbe that causes botulism, a type of food poisoning.
-These botox injections have the ability to reduce the appearance of some facial wrinkles. They are also used to treat such problems as repetitive neck spasms, excessive sweating, overactive bladder and lazy eye.
-Botulinum toxin acts by binding presynaptically to high-affinity recognition sites on the cholinergic nerve terminals and decreasing the release of acetylcholine, causing a neuromuscular blocking effect.
<span>The correct answer is The cell is eukaryotic because it has chloroplasts. Prokaryotic cells don't have chloroplasts as they are only found in eukaryotic cells. The closest thing there is to chloroplasts are the cyanobacteria who function similarly and also photosynthesize but are in the end not chloroplasts themselves.</span>
The solute potential is expressed in the formula P= – iCRT, where i = the ionization constant, C = the molar concentration , R = the pressure constant (R = 0.0831 liter * bars/mole * K), and T = the temperature in K (273 + °C). At atmospheric pressure and 25°C has an osmotic potential - A 0.15 M NaCl solution contains 2 ions, Na+ and Cl- (where sucrose stays as one particle); therefore i = 2, and the water potential = -7.4 bars.
Water will move into the cell by osmosis from 0.1 to 0.15.
Parents can pass on chromosomes to their children that are different than their own when the new gene combinations are created by d) crossing over of homologous chromosomes during meiosos
A. multiply the chance that it will be a boy x the chance he will have PKU (1/2 x 1/4)
<span>B. chance of having PKU + chance of albinism </span>
<span>C. chance PKU x chance albinism</span>
