Hiya once again,
The fluid mosaic model explains only but observations about the structure of functioning cell membranes. However, a lipid bilayer is used to describe the membranes of animals and plant cells. This isn't a great question to be honest with you, so let's try it like this:
Triglyceride: Ester formed by Glycerol and 3 fatty acid groups. These guys are basically made up of fats and oils. (Ex- High concentrated blood)
Phospholipid: A lipid containing a phosphate (an ester of phosphoric acid) in its molecule.
Bilayer: A film (layer) of molecules (created by lipids) that are arranged with it's hydrophobic (meaning whatever it is does NOT mix well with water... Kinda like pouring sugar into a cold glass of water and waiting for the sugar to melt) inverted at both ends of the film.
Embedded Proteins ('Intrinsic Proteins' if you wanna be fancy): Having one or more segments embedded into the phospholipid bilayer.
Stationary (phase): This is something that is mostly involved with bacterial growth
I really hope this helps! Let me know what you got and which one was right!
Answer:
A. Botulinum toxin possesses a heavy chain and a light chain, each of which takes part in the toxicity. The binding of the protein and its invasion within a nerve cell is permitted by the heavy chain. After the entry is permitted, the light chain functions like a protease and chops proteins, which would usually permit neurotransmitters to discharge out from the cell. This is basically a commotion of exocytosis or the discharging of neurotransmitters.
The acetylcholine, that is, the obstructed neurotransmitter generally conducts a nerve impulse to a muscle, allowing the muscle to contract. By inhibiting the neurotransmitter, the botulinum toxin results in its distinctive flaccid paralysis.
B. The small doses of the sterile, purified botulinum toxin when used in a medical setting as an injectable form prevent the release of a chemical known as acetylcholine by the nerve cells, which signal contraction of the muscles. By selectively interfering with the underlying tendency of the muscles to contract, the prevailing frown lines are smoothed out, and in the majority of the cases are almost invisible for a week.
G . because the bat population will change with no bugs.
It would be uracil (C)
thymine would be complementary to adenine in DNA but because it is RNA it is replaced by uracil.
HURRICANE is the answer! Have a good day! Hope this helped!
