Answer:
When the pKa is 6.0, we can determine the fraction of protonated H is by:
pH = pKa + log [A]/[HA]
Where
A = Deprotonated imidazole side
HA = Protonated side
Given, pH = 5.0
5 = 6 + log [A]/[HA]
log [A]/[HA] = -1 (take antilog of both side)
[A]/[HA] = 0.1
The ratio of the deprotonated imidazole side chain to the protonated side chain at pH 5.0 = 0.1
Given, pH = 7.5
7.5 = 6 + log [A]/[HA]
log [A]/[HA] = 1.5 (take antilog of both sides)
[A]/[HA] = 31.62
The ratio of the deprotonated imidazole side chain to the protonated side chain at pH 5.0 = 31.62
Marble is formed from limestone and contains tiny interlocking grains.
Your answer is C.
Answer: Nucleiod, Ribosomes, flagella, fimbriae, plasma membrane
Explanation: A typical bacteria cell possess these structures mentioned above. nucleiod is a chromosome , a nucleic acid which can be DNA or RNA, It is the genetic material of cell which every bacteria cell must have. Flagella ensures swimming movement of all bacterial cell. Ribosome of bacteria cells ensures protein synthesis. Since all bacteria cells meet, plasma membrane is permeability barrier, location of enzyme and transports solutes. Fimbriae enables bacterial cells attachment to surfaces
When you rub a ballon in your hair.
Answer:
Yes it is helpful
Explanation:
Not only do we live in harmony with these beneficial bacteria, but they are actually essential to our survival. Good bacteria help our bodies digest food and absorb nutrients, and they produce several vitamins in the intestinal tract — including folic acid, niacin, and vitamins B6 and B12.
