Options are no given in the question. The complete question is as follows:

If autophosphorylation of CheA protein does not occur, then Escherichia coli cells must be_________________.

A. in a gradient of a chemoattractant.

B. in a gradient of a chemorepellant.

C. tumbling.

D. rotating flagella clockwise.

Answer:

A. in a gradient of a chemoattractant

Explanation:

The autophosphorylation of CheA is described as the autophosphorylation of histidine kinase (s) (CheA protein) in the presence of MgCl 2 and ATP.

If autophosphorylation of CheA protein does not occur in Escherichia coli, then the cells of E.Coli undergo methylation events that allow cell in a gradient of chemoattractants which increases the activity of CheA and CheY-P and cells adapt according to the concentration of chemoattractant.

Hence, the correct answer is A.

The map of a walking trail is drawn on a coordinate grid with three points of interest. The trail starts at R(−2, 4) and goes to

Zinaida [17]

Answer:

The total length will be "10 units". A further explanation is given below.

Explanation:

The given points are:

R(−2, 4)

S(3, 4)

T(3, −1)

On applying the distance formula,

⇒ $RS=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

⇒ $=\sqrt{(3-(-2))^2+(4-4)^2}$

⇒ $=\sqrt{(3+2)^2+(0)^2}$

⇒ $=\sqrt{25}$

⇒ $=5 \ units$

and,

⇒ $ST=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

⇒ $=\sqrt{(3-3)^2+(-1-4)^2}$

⇒ $=\sqrt{0+(-5)^2}$

⇒ $=5 \ units$

Now,

The total trail length will be:

= $RS+ST$

= $5+5$

= $10 \ units$
