The answer to this question is summer I know this for a fact cause I took biology last year your welcome
Plants absorb water from the soil by osmosis. They absorb mineral ions by active transport, against the concentration gradient. Root hair cells are adapted for taking up water and mineral ions by having a large surface area to increase the rate of absorption.
PCR, or polymerase chain reaction is used to take a section of dna and force it into a - millions of identical copies of a DNA fragment
PCR (Polymerase chain reaction) - It is defined as a technique that is used to make millions of identical copies of a DNA fragment in a few hours. This technique is commonly used for a variety of applications like- genotyping, cloning, mutation detection, sequencing, micro arrays, forensics, and paternity testing etc.
An enzymatic weight-gain supplement claims to help users digest all carbohydrates in fruits and vegetables. Cellulase enzyme is present.
<h3>What is cellulase ?</h3>
Cellulase (systematic name 4—D-glucan 4-glucanohydrolase) is any of a number of enzymes that catalyse cellulolysis, the breakdown of cellulose and some related polysaccharides, and is primarily produced by fungi, bacteria, and protozoans.
Endohydrolysis of (14)-D-glucosidic linkages in lichenin, cereal -D-glucan, and cellulose
The term is also applied to any naturally occurring combination or complex of numerous such enzymes that break down cellulosic material sequentially or cooperatively.
Cellulases convert the cellulose molecule into shorter polysaccharides and oligosaccharides, as well as monosaccharides (or "simple sugars") like -glucose. Because it makes a key plant component usable for food and use in chemical reactions, cellulose breakdown has significant economic significance. The 1,4-D-glycosidic bonds in cellulose, hemicellulose, lichenin, and cereal -D-glucans are hydrolyzed in this particular process. Compared to the breakdown of other polysaccharides like starch, the breakdown of cellulose is particularly challenging because the molecules of cellulose bind tightly to one another.

Answer:
Enzyme: A biomolecule that speed up the rate of chemical reactions without being used up.
Substrate: A substance or chemical that enter the chemical reaction and is being converted into a new substance (product).
Competitive enzyme inhibition: Inhibition of enzyme's activity by binding of inhibitor to substrate binding site of the enzyme.
Explanation:
Enzymes are the biomolecules that serve to increase the rate of reactions by lowering down the required activation energy. The enzyme is never used up during reactions.
Substrates are the chemicals that undergo a chemical change and produce products.
For example, Glucose is the substrate for hexokinase enzyme and is converted into glucose 6 phosphate (the product).
When the inhibitor competes with the substrate for the binding site on the enzyme and does not allow the substrate to bind to the enzyme, the process is called competitive enzyme inhibition. It can be overcome by increasing the concentration of substrate in the system.
