Answer:
Enzymes are biological catalysts. Catalysts lower the activation energy for reactions. The lower the activation energy for a reaction, the faster the rate. Thus enzymes speed up reactions by lowering activation energy.
Answer: monosaccharides are simple sugars made up of only a single sugar molecule. Disaccharides are sugars made up of two sugar molecules linked together by a glycosidic bond while polysaccharides are complex sugars made up of many sugar molecules linked together by glycosidic bonds.
Explanation: Examples of monosaccharides are glucose, fructose, and galactose, while examples of disaccharide sugars include maltose, lactose and sucrose. Examples of polysaccharides include glycogen
and starch.

Explanation:
The front of the white paper packet of the OSL dosimeters may be color-coded to facilitate correct usage and placement of the badge on the body of occupationally exposed personnel.
OSL dosimeters are recently developed and are of high quality than thermoluminescent dosimeters. It is used to monitor patients health status. Furthermore, it is very sensitive to any change or drop in reading. it give accurate readings even at 1 mrem for both gamma ray photos and X-rays.

Body’s of water i think
Dead zones occur because of a process called eutrophication, which happens when a body of water gets too many nutrients, such as phosphorus and nitrogen. ... Human activities are the main cause of these excess nutrients being washed into the ocean.
