Heat sodium thiosulfate in a water bath. The solid crystals will dissolve into the water in the hydrated crystals forming a supersaturated solution. Placing a small crystal in the supersaturated solution will cause the liquid to turn solid.
What is sodium thiosulphate?The inorganic compound sodium thiosulfate, sometimes known as sodium thiosulphate, has the formula Na2S2O3.xH2O.
It can be found as the pentahydrate which is white or colorless. The solid is a crystalline efflorescent (quickly loses water) substance that readily dissolves in water.
Gold mining, water purification, analytical chemistry, the creation of silver-based photographic film and prints, and medicine all make use of sodium thiosulfate.
The treatment of cyanide poisoning and pityriasis are among the medical applications of sodium thiosulfate. It is among the safest and most useful medications required in a healthcare system.
Therefore, Heat sodium thiosulfate in a water bath. The solid crystals will dissolve into the water in the hydrated crystals forming a supersaturated solution. Placing a small crystal in the supersaturated solution will cause the liquid to turn solid.

If albumen is broken down by a protease, what sort of chemical is albumen?
Albumin is broken down by the activity of protease enzyme, this enzyme is responsible for the digestion of proteins. Therefore, albumin is chemically protein in nature.
What is Albumin?
Albumin is a family of proteins. These are globular proteins in which the most common are the serum albumins. All the proteins of the albumin family are water-soluble and moderately soluble in concentrated salt solutions. This protein denatures on continuous heat treatment.
Albumins are commonly found in blood plasma. It differs from other blood proteins as they cannot be glycosylated. Substances which contains albumin proteins are called albuminoids.
A number of blood transport proteins are found to be evolutionarily related in the albumin family such as serum albumin, alpha-fetoprotein, vitamin D-binding protein and afamin. This family of proteins is only found in vertebrates.

There are two types of karyokinesis: mitosis and meiosis. When a nucleus divides by mitosis, how much of the information from the nuclear chromosomes is passed on to the daughter cells
When a nucleus divides by mitosis, all of the information from the nuclear
chromosomes is passed on to the daughter cells.
Mitosis is a cell division process that results in the formation of two daughter cells during growth processes and in the replacement of worn-out tissues in the body.
The cells produced must have all the information as the cells replicated
have specialized functions which must be passed from parent cells to the daughter cells.

A. antibiotics are used to kill bacteria, which are alive.
B. antibiotics are used to treat sick humans, and humans are living organisms.
C. antibiotics are viruses that have been deactivated but we're once alive.
D. antibiotics were first isolated from a living origin: mold.
Antibiotics are compounds capable of killing bacteria. This is biotechnology because antibiotics were first isolated from a living origin: mold. The correct option is D.
What are antibiotics?When the body develops a resistance to antibiotics, antibiotic resistance happens. Antibiotic abuse or overuse is what led to antibiotic resistance. When germs develop resistance to medications meant to kill them, it happens.
Because antibiotics are unable to combat bacteria, the bacteria grow and produce illnesses that can result in life-threatening infections, incapacity, or even death.
The overuse or improper use of antibiotics was somehow the cause of all antibiotic resistance. It takes place when the bacteria completely lose their ability to be killed by drugs and instead develop a resistance to them.
Therefore, the correct option is D. antibiotics were first isolated from a living origin: mold.
