The answer to the question is the Marine snow.
In the deep ocean, marine snow is a continuous shower of mostly detritus falling from the upper layers of the water column. It is a significant means of exporting energy from the light-rich photic zone to the aphotic zone below. Marine snow particles are found throughout the world's oceans in all parts of the water column.
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.

Explanation:
Root hairs are found in the plant it is a hair-like structure present on the surface of the root tip and Root hairs have large surface area that increase the absorption rate of water and minerals.
Water is absorbed by root hair cells through the process called Osmosis and Minerals ions is absorbed root hairs by the process called active transport.
The function of root hair is to collect the minerals and waters present in the soil and then transfer these nutrients and water through roots to different parts of the plant.
Answer
To decrease the PH of a neutral solution add to it an acidic substance such as lemon juice.
Explanation
The p H (potential of hydrogen) is the level of an aqueous solution which tells us how acidic or basic a substance/solution is based on it hydrogen ion concentration. The higher the concentration of hydrogen ions, the lower the p H. In distillated water that has a p H of 7(neutral), you can increase the p H of the water by adding an alkaline substance such as baking powder.
