Answer:
Ninhydrin causes prints to turn a purple color, which makes them easily photographed. DFO (1,2-diazafluoren-9-one) is another chemical used to locate latent fingerprints on porous surfaces; it causes fingerprints to fluoresce, or glow, when they are illuminated by blue-green light.

In 1873, Joseph Lister isolated the first bacterial pure culture which he called Bacterium lactis. This lactic acid bacterium is now called Lactococcus lactis and is used for fermenting milk to produce hundreds of different dairy products.
Supergiant stars can have masses from 10 to 70 times greater than our Sun. When it comes to brightness, some of them can be from 30,000 times or brighter than our Sun. The temperature range of a supergiant spans from around 3,450 K to 20,000 K. The absolute visual magnitudes between -3 and -8.
Answer:
Explanation:
Active transport is the movement of molecules or substance from a region of lower concentration to a region of higher concentration across a cell membrane against the concentration gradient.
Active transport requires cellular energy and are of two types:
primary active transport that uses adenosine triphosphate (ATP), and secondary active transport that uses an electrochemical gradient.
Active transport helps in the uptake of glucose in the intestines.
Cotransport or secondary active transport is the movement of molecules across a membrane it uses electrochemical potential difference that is created by pumping ions in or out of the cell.
Cotransport helps in the transport of glucose across the cell membrane.
One of the functions of the gallbladder is to store bile. The bile in the gallbladder tends to be excess from the liver, and is used throughout the digestion process.
Fun Fact: While the gallbladder aids in digestion, it is not required, and humans can survive without it!
