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

which of the following best describes the students measurements
the students measurements were accurate, but not precise
the students measurements were precise, but not accurate
the measurements are neither accurate nor precise
the measurements are both accurate and precise
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.
Answer:
ocelots are known to really enjoy small rodents, like mice, but they also eat a variety of other things including birds, snakes, iguanas, different types of lizards, lil baby peccaries :(, young deer, bunnies (why-), and even seafood, like fish and crabs.
