ankoles [38]3 years ago
6 0

Sampling

- counting the number of organisms in a small area and multiplying to estimate the number in a larger area

Mark & Recapture

- capture an organism & release it to remix with population. Then recapture some more in that area to determine population size. Formula is as follows: R (marked recaptures) / C (total in second sample) = M (marked initially) / N (total pop. size)

Indirect Observation -

estimating the population size by tracks, nest or other animal signs in an ecosystem.

ASHA 777 [7]

Answer:

150 - 300 bp

Explanation:

Micrococcal nuclease, indistinctly from the time of treatment and in average organisms, will realize the cuts on DNA o RNA zones rich in AT or AU. It is not a specific endonuclease.

Even so, the mean size of the expected fragments will have between 150 bp and 300 bp.

It is very important to run your digestion along with a proper label.
