Answer:
it increases speed of chemical reaction
Enzymes are proteins that speed up chemical reactions by lowering the activation energy, or the energy required for a reaction to take place. This makes reactions happen more efficiently and quickly.
An enzyme is a type of protein that accelerates, or catalyzes, chemical reactions. In relation to their effect on the energy of a chemical reaction, enzymes lower the activation energy. The activation energy is the energy threshold that must be met in order for a chemical reaction to occur. By decreasing this energy barrier, enzymes facilitate the process and make it proceed faster than it would without the enzyme.
For example, let's take the digestion of food in your body. The enzymes present in your digestive system speed up the chemical reactions that break down large food molecules into smaller units. This is because these enzymes reduce the activation energy required for these reactions, enabling the reactions to happen more efficiently and quickly.

Answer:
I don't know exactly what you need but I give you an example so that you can create your samples through the Excel program, I hope it helps.
Just enter your sampling frame (the clients of which you have contact information) in the spreadsheet. Once you have a sampling frame (possible respondents) in Excel, you can easily select a random sample among them. For example, in your case that it is a work of biology and neceists three random samples here you can apply it with the following rules:
-Add a new column in the spreadsheet and name it "Random Number".
-In the first cell below your header row, type "= RAND ()".
-Press “Enter” and a random number will appear in the cell.
-Copy and paste the first cell in the other cells of the column.
-Once each row has a random number, organize the records from the "Random number" column.
-Then, select the first samples. In this way you will randomly choose from all samples.

Answer:
Pepsin is an enzyme present in the gastric juice which digests the proteins of the food material.
These pepsin are synthesized as pre-proenzymes or inactive forms by chief cells in the gastric mucosa of the stomach. These inactive forms consist of a signal peptide, activation peptide and active enzyme which gets activated in the acidic environment of stomach by Hydrochloric acid.
The stomach secrets this enzyme in an inactive form to prevent the digestion of protective proteins present in the lining of the digestive tract.
Answer:
All of the above are true.
Explanation:
Microbial cells are surrounded by the plasma membrane or cytoplasmic membrane. It serves as a selective barrier allowing materials in and out of the cell e.g. allowing nutrients in and waste out.
Microbial cells grow independently, in that they are unicellular, and so do not depend on the other cells to carry out the process. However, they rely on nutrients, and in some environments, these may be nutrients produced by other organisms.
Microbial cells are unicellular, although some microorganisms are multi-cellular. Microorganisms such as bacteria are unicellular, that is, exist as single cells.
Bacteria and viruses are microorganisms.
