B. a seismograph detects earthquake activity, while a seismogram measures the depths of the earth's layers.
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.

Yes that is true.................
Georgio is jogging barefoot along the beach when he suddenly steps on the sharp edge of a broken shell. He instantly feels pain due to the message carried to his brain by<u> dendrites.</u> He then slowly walks home with an achy foot. The message of the ache is carried by <u>neurons.</u>

The nervous system has electrical cells that are trained to transmit and receive messages. Through the use of electricity, people can communicate by transmitting messages to one another. This voltage is produced in neurons by the movement of charged ions. salt atoms with positive or negative charges that pass through the cell membranes and cross the cell's outer membrane. The neuron has dendrites, which are branches (like a tree) that receive messages, and an axon, which is a longer, more straightforward projection (like a tree trunk), that sends information. Synapses. Axon ends include the neuron communication junction, where vesicle fusion releases chemical signals. Neurotransmitters are the chemical messages that the nerve cell releases.
