Please help me! During the replication phase, DNA: A. copies itself
B. splits into two daughter cells
C. moves to opposite ends of the cell

Answer:

m = density x volume

The density of O2 is 1.429g/L

1.429g/L x 1L = 1.429g

1.429g/32g/mol = 0.045 moles

Answer:

Explanation:

Q1. For assuring accuracy and precision we have to take into account statistical values such as absolut error, relative error and standard deviation. Errors(absolute and relative) are related to accuracy, and they tell you how much you are getting away from the correct answer. Standard deviation tells you how precisa your measure was, that means how many times you hit on the objective.

standard deviation can be added to the result as

Q2.

Q1: sort your numbers into numerical order so you can determine the highest and lowest measured values. and then subtract the lowest measured value from the highest measured value. Now determine that the answer is the precision.

Q2: In one meter there are 100 centemeter. Now you got 5.8 miles per hour which will become 580 centemeter per hour. In addition, there are 60 minutes in an hour. Based on what we know, 580 centemeters per hour will and should become 580/60 cm/min

Answer:

Explanation:

Givens

P = 1.25 atm

V = 5.4 L

P1 = 3 atm

V1 = ??

Formula

The basic formula is P*V = P1 * V1

Solution

1.25 * 5.4 = 3 * V1

6.75 = 3*V1

6.75 /3 = 3*V1/3

2.25 = V1
