Answer:
c latititude
Explanation:
Latitude or distance from the equator – Temperatures drop the further an area is from the equator due to the curvature of the earth. In areas closer to the poles, sunlight has a larger area of atmosphere to pass through and the sun is at a lower angle in the sky.
I don't know if you know but there is no diagram
While the absorbance at 420 nm is related to the amount of o-nitrophenol produced, the absorbance at 600 nm is proportional to cell density, which aids in standardizing our estimations of enzyme activity.
<h3>Describe absorbance.</h3>
The amount of light absorbed by a solution is measured by its absorbance (A), often referred to as optical density (OD). The amount of light that may flow through a solution is called its transmittance.
<h3>How is the activity of beta-galactosidase determined?</h3>
The colorless ONPG substrate is changed by beta-Galactosidase into galactose and the chromophore o-nitrophenol, which results in a vivid yellow solution. The amount of substrate transformed at 420 nm can be calculated by measuring the solution's beta-galactosidase activity using a spectrophotometer or a microplate reader.
<h3>What is measured by the beta-galactosidase assay?</h3>
The -Gal Assay Kit gives users the tools they need to swiftly assess the amounts of active beta-galactosidase expressed in cells that have been transfected with plasmids encoding the lacZ gene.
