B is your answer for that question
Answer:
A marine biologist is more in demand. A marine biologist is a scientist who studies plants and animals that live in the ocean. A marine biologist seeks to understand ecosystems, biology and behaviors while analyzing how different marine species interact with each other. Besides studying how ocean life affects itself, marine biologists may also examine the impact that human interaction has on marine biology. Explanation:
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.
