Didn't you say that the water at 39 degrees is more dense than water at its freezing point? I think the reason organisms would die is because the water already starting to structure in a crystal form, when it starts to freeze into ice. This probably why it kills the organisms, is because the water ceases to allow the organism to function at those temperatures.
The cell wall of <em>Mycobacterium </em>is accountable for its slow growth, being <em />strongly impermeable to nutrients, and for its compact, wrinkled appearance in colony morphology. Most nutrients are hydrophobic such as certain fats and vitamins as well as some form of carbohydrates and proteins. Since the cell wall is hydrophobic, nutrient absorption of <em>Mycobacterium</em> is slow hence growth of the organism is also slow. A wrinkled colony appearance is also characteristic of microorganisms with hydrophobic cell walls.
On the other hand, while <em>Mycobacterium</em> is an aerobic organism; the hydrophobicity of the cell wall do not account for this characteristic of the organism.
Answer:
Tardive dyskinesia is often associated with long-term use of drugs that occupy certain DOPAMINE receptor sites, which serves as a neurotransmission site between the nerve cells (neurons) of the brain.
Nine amino acids are needed to travel through the thickness of the membrane.
Alpha-axial helix's distance between amino acids is 1.5. A
The number of gaps between the 22 amino acids in the helix is equal to (22-1) = 21.
Therefore, the helix's length is (21 X 1.5) = 31.5.
One alpha helix is sufficient to span the membrane's breadth, hence the formula is: span of the helix = thickness of the membrane = 31.5 A
The thickness of the membrane is determined by the formula above to be 31.5 AA.
In the beta-strand, there is 3.5 AA between each amino acid.
Therefore, (31.5/3.5) = 9 amino acids are needed.
