The five steps of the water treatment process - in order - are coagulation, sedimentation, filtration, disinfection, and storage. Define one of the steps.
Coagulation: Adding a chemical to a water to form clumps that are heavy enough to sink.
Sedimentation: When clumps of dirt and other waste are removed from the liquid.
Filtration: Passing the water through a membrane to separate small particles from the solution.
Disinfection: Cleaning the water using chemical to kill harmful microbes that may be in the water.
Storage: Holding treated water in a closed tank to keep it disinfected.
What are 2 effects of drought?
What are "environmental effects (damage to habitats, soil erosion, wildfires), economic/social effects (crop loss, unemployment), and unavailability of water for daily use"?
Chromosomes are made up of what type of protein?
What is DNA?
There are two different types of virus cycles.
In the _______ cycle, a virus injects its DNA into a host cell, replicates rapidly, and causes the host cells to burst releasing many new microbes to infect other cells in the body.
In the __________ cycle, a virus injects its DNA into a host cell so that the host cell will continue to replicate and make more cells with the virus. Eventually, the other cycle will be triggered, and all the infected virus cells will become active.
What are the lytic and lysogenic cycle?
What does a phagocyte do?
It is a white blood cell that helps the immune system by "eating" and breaking down foreign bacteria or other small microbes that infect the body.
A solution is a liquid mixture. A solute is the thing that is dissolved in a solvent, or the liquid in which the dissolving occurs.
