Which of the following is a concern if you forgot to resuspend (mix) culture solutions when performing serial dilution?

Biology

Answer:

B) CFU/mL calculations would not be accurate

Explanation:

In microbiology CFU is the acronym for Colony Forming Unit, which indicates the number of bacteria or fungi capable of multiplying under suitable conditions. In this case, CFU/mL indicates how much bacterial or fungal cells, susceptible to reproduction, exist within 1 mL of a culture solution.

When this solution is used, to make a dilution or other laboratory activity, it is important that it be resuspended, that is, mixed, as the bacteria or fungus cells can accumulate in the bottom or surface of the substance, changing the value of CFU/mL and causing inaccurate dilutions if used. When resuspended, the substance presents the appropriate value of CFU/mL, ensuring that the dilution is accurate and effective.

How does loseing laforin give you epilepsy ( please use lots of detail in the answer)
Deffense [45]
<span>Lafora disease is the most severe teenage-onset progressive epilepsy, a unique form of glycogenosis with perikaryal accumulation of an abnormal form of glycogen, and a neurodegenerative disorder exhibiting an unusual generalized organellar disintegration. The disease is caused by mutations of the EPM2A gene, which encodes two isoforms of the laforin protein tyrosine phosphatase, having alternate carboxyl termini, one localized in the cytoplasm (endoplasmic reticulum) and the other in the nucleus. To date, all documented disease mutations, including the knockout mouse model deletion, have been in the segment of the protein common to both isoforms. It is therefore not known whether dysfunction of the cytoplasmic, nuclear, or both isoforms leads to the disease. In the present work, we identify six novel mutations, one of which, c.950insT (Q319fs), is the first mutation specific to the cytoplasmic laforin isoform, implicating this isoform in disease pathogenesis. To confirm this mutation's deleterious effect on laforin, we studied the resultant protein's subcellular localization and function and show a drastic reduction in its phosphatase activity, despite maintenance of its location at the endoplasmic reticulum.

What are the three elements of an editorial?
Vika [28.1K]

Answer:  the introduction, the body, and the conclusion

Explanation:

An editorial piece is meant to show the opinion of the newspaper on a certain issue. It is usually written by the senior editor or the publisher and is the first article on the written piece.

Editorials follow a common writing structure that begins with an introduction where the issue is introduced. Discussions are then made in the body and the conclusion will then round up the piece.
