Answer:
The options are
tapping the base of the pipette on the table
using subtraction to determine the volume dispensed
making sure that you read the volume with the liquid inside the pipette at eye level
reading only the final volume of liquid after dispensing
ensuring that air bubbles are not in the column of liquid inside the pipette
The answer is
using subtraction to determine the volume dispensed
making sure that you read the volume with the liquid inside the pipette at eye level
ensuring that air bubbles are not in the column of liquid inside the pipette.
Explanation:
A pipette is an instrument used in the laboratory for transporting and movement of liquid substances for various experiments. It is usually graduated to ensure accurate measurements of the liquid substance.
To ensure accurate reading of volume from a graduated pipette, precautions listed should be taken:
Using subtraction to determine the volume dispensed
Making sure that you read the volume with the liquid inside the pipette at eye level
Ensuring that air bubbles are not in the column of liquid inside the pipette.
Answer:
The correct answer is option A.
Explanation:
The histone acetylation catalyzed by histone acetyltransferases and deacetylation catalyzed by histone deacetylases performs a significant role in the regulation of the expression of genes in eukaryotes. Histone acetylation diminishes the affinity of histones towards DNA leading to relaxing or decondensation of chromatin and becomes accessible to the transcriptional apparatus and to perform transcription.
It can be stated that histone acetylation is related to expression or gene or activation and histone deacetylation is related to the inactivation of gene or repression.
Answer:
96mm
Explanation:
alright so since it had length, width, and height pf 4mm i guess it's a cube cell. the formula for the surface area is just n^3 (literally n cubed, easy to remember) where n is the length/width/height. 4mm^3=96mm, so the surface area of the cell is 96mm.
