Phosphorylation of CheY regulates which direction a flagellum rotates, thus controlling whether an organism runs or tumbles. The phosphorylation of CheY together with the co-regulation of acetylation is used as a response regulator for the Escherichia coli, a bacterial flagellum.

Answer:
18.28
Explanation:
Given:
Relation between the absorbance (y) and the concentration (x) as ;
y = 0.057x + 0.069
now,
we have to calculate concentration (x) for the given value of absorbance (y) = 1.111
thus, on substituting the value of y = 1.111 in the above relation, we get
1.111 = 0.057x + 0.069
or
x = 18.28
hence, the <u>value of concentration of sample is 18.28</u>
Answer:
D. her skeleton was 40% intact and undisturbed
Explanation:
Lucy was one of the most important discoveries in human evolution. Before the finding of Lucy majorities of the human ancestor bones were not much more than only some bone fragments.
Lucy was the first most complete Australopithecus which was ever found. Lucy was approximately 40% complete fossil. It was found that her brain size was smaller than today's man but she was bipedalism. She was a new species of Australopithecus- Australopithecus afarensis. So the right answer is D.
Answer:
3
Explanation:
Allowing the thermometer bulb to touch the beaker will result in inaccurate readings because the thermometer will conduct heat from the beaker. This will be worse especially if the beaker is not at temperature equilibrium with the liquid inside. Also, don't handle the thermometer until the temperature levels off.
