If any hero knows what s going on, just tell me, and I m grateful!

I don't have the strength to sleep, probably because I have diarrhea. Drinking 10% glucose is effective, (the kind of 500ci sling injection), one bottle at a time, and drinking several bottles in a row, it may be fine.

First of all, you have a problem with the clarity of this **, and you really can't see it clearly.

Reset the network or use a 360 first aid kit.

Judging from your **, there is no problem, you press its shell with your hand, if there is any soft place, if there is it, it is nail rot.

The dorsal or ventral carapace of the turtle initially appears with white spots, which slowly form red spots, and blood oozes out when pressed hard, and has a rancid smell. In severe cases, the surface of the carapace will ulcerate into holes, and the armpits and crotch will bulge. Sick turtles stop eating and move less, and there is a phenomenon of head shrinkage.

Four-eyed turtles, side-necked turtles, and snake-necked turtles are highly susceptible to this disease.

The amount of NaOH in 300ml solution is 60 40 = 300ml of the original solution The concentration of NaOH in the original solution is set to take x l of the original solution, add y l water, then there is.

5x/(x+y)=1

The solution is x:y=1:4

c1*v1=c2*v2)

Choose C. If the original solution x is added and distilled water y is added, then divide by x+y equals 1 to obtain the answer c

The molar mass of NaOH is 40g mol 60gnaoh has the concentration of the original solution.

Suppose the original solution is fully prepared into 1mol L of NaOH solution, which is inconvenient to obtain from the amount of substances in the solution

The solution is x=, i.e. the water added is liters. Choose A

The original solution concentration is 60*1000 40*300=5 mol liters.

5*300=1*x, x=1500, add 1500-300=1200 ml of water.

Let the three numbers a, b, and c, and have the following equation.

a*b*c=512...1)

b/a=c/b...2)

c-2-b=b-a+2...3)

The two equations from (1) and (2) b = 8

Substituting two equations (2) and (3).

a*c=64...4)

c=20-a...5)

Substitute (5) with (4).

a=4c=16

Results: a=4, b=8, c=16

Analysis 1: There is only one falsehood.

Assuming that condition 1 is false, then condition 2 is true (true) and condition 3 is not true (false).

Assuming that answer 2 is false, then condition 1 is true (true) and condition 3 is true (true).

Assuming that condition 3 is false, then condition 1 is not true (false) and condition 2 is true (true).

Therefore, the inference is true only if condition 2 is false. According to the description of conditions 1 and 3, all 10 people in the institute, including the director, are doctors.

Analysis 2: There is only one true sentence.

Assuming that condition 1 is true, then condition 2 is true (false), condition 3 is not true (true) Condition 2 is true, then condition 1 is true (false), condition 3 is true (false) Condition 3 is true, then condition 1 is not true (true), and condition 2 is true (false), i.e., the director is not a doctor.
