what would happen if the relative concentration ofxygen inside the lung snf in teh blood became equal to each other

Answer:

The serial dilution can be done by half- logarithmic dilution method.

Explanation:

• This is also called the Ten-fold dilution method.
• The process involves the following steps, and the volumes represented are arbitrary.

1. From the concentrated solution of the disinfectant take 1 ml of disinfectant in a falcon tube. 9 ml of water is added to that. Here we get a solution which is   diluted.
2. Take 1 ml of the above diluted solution in another falcon and add 9 ml of water to it. Here we will get a solution which is   diluted.
3. Take 1 ml of the above diluted solution in another falcon and add 9 ml of water to it. Here we will get a solution which is   diluted.
4. Take 1 ml of the above diluted solution in another falcon and add 9 ml of water to it. Here we will get a solution which is   diluted.

Final answer:

To prepare a serial dilution, you start with the stock solution and dilute it step-by-step. For a 1/20 dilution, take 1 part solution and add 19 parts solvent. For a 1/40 dilution, dilute the 1/20 solution further by taking 1 part of the 1/20 dilution and adding 1 part solvent. Similarly, for a 1/80 dilution, take 1 part of the 1/40 dilution and add 1 part solvent.

Explanation:

To prepare a serial dilution, you start out with a stock solution (in this case, the disinfectant) and dilute it step by step. To prepare the 1/20 dilution, you take 1 part stock solution and add 19 parts solvent. Then for a 1/40 dilution, you can dilute the 1/20 solution by a further factor of 2: take 1 part of the 1/20 dilution and add 1 part solvent. The same principle applies for the 1/80 dilution: take 1 part of the 1/40 dilution and add 1 part solvent, or you could take 1 part of the original stock solution to 79 parts of solvent.

Answer:

Option , B, the students measurements were precise, but not accurate

Explanation:

It is given that the acceptable value for the paper clips is 1.14 grams.

An accurate value is the one which is close enough to the accurate answer and in case when the number of readings taken with in an experiment are close to each other then they are said to be precise.

Here the value obtained through three reading are close to each other hence, they are precise but none of these values is close to the acceptable value for the paper clips.

Hence, option B is correct.
