Answer:
cools down and water helps it
Explanation:
Answer:
Most polymers, including poly(ethene) and poly(propene) are not biodegradable . This means that microorganisms cannot break them down, so they: cause a litter problem if disposed of carelessly. last for many years in landfill sites.
Answer:
All the given statements are correct except b.
Antimicrobial resistance (AMR) refers to the ability of a microorganism to grow in the presence of drug or a chemical that would normally limit its growth or kill it.
It makes it difficult for the existing drugs to eliminate the infection as they become less effective against the microbe.
There are five major mechanisms by which a microbe attains resistance against antimicrobial chemical or drug:
- Drug modification or inactivation: A microbial enzyme inactivates the antimicrobial agent. For example, few bacteria produce β-lactamases which provide multi-resistance against β-lactam antibiotics such as penicillin, cephalosporin etc.
- Alteration or modification of target site: An altered target site prevents the antimicrobial agent from binding to its target. For example, alteration of penicillin binding protein (PBP) in Methicillin-resistant <em>Staphylococcus aureus </em>(MRSA).
- Alteration of metabolic pathway: The microbe uses an alternative pathway to circumvent the blocked pathway. For example, sulfonamides-resistant bacteria started using preformed folic acid in place of para-aminobenzoic acid (PABA).
- Decreased drug accumulation: Microbial efflux pumps remove the antimicrobial agent (before it could do any damage) by pumping it out of the cell.
- Decrease in cell permeability: The permeability of the microbial envelope to the antimicrobial agent is decreased
Answer:

Then you add 3 drops in the milk
Because it will affect the color of the milk
Answer:
The monosaccharide that results from complete hydrolysis of amylose is GLUCOSE.
Explanation:
Amylose is a crystalline form of starch, it is made up of linear polysacharride chains that are joined together by mean of alpha 1, 4 glycosidic bonds. Hydrolyisis refers to the breaking down of a substance into its basic units. The basic unit of amylose is glucose, that is, amylose is made up of long chains of glucose. Therefore, when amlyose is hydrolyze, the monosaccharide that will result from the hydrolysis reaction is glucose.
This is what happens during digestion; when consumed starch is acted upon by amylases (enzymes that act on amylose) it is broken down into glucose, which can be used by the body for generation of energy.
