Class IV and Class V mutations would be less likely to lead to Cystic Fibrosis (CF).
Class IV mutation or Conduction mutation involves reduced chloride conductance. It changes the shape of the protein channel so that chloride cannot move easily in and out of the cells. Less than 3% of people with cystic fibrosis in Europe have this type of mutation.
Class V or Insufficient Protein mutation is associated with reduced protein levels. It results in a reduction in the amount of CFTR protein produced by the cells. Less than 3% of people with cystic fibrosis in Europe have this type of mutation.
These two classes of mutations cause a milder reduction in CFTR function.

Cell stained light for the metaphase test and dark for the SDH, then we can classify the cell as an oxidative cell.
<h3>What is metaphase?</h3>
Metaphase, the second stage of mitosis, sees the chromosomes travel onto the spindle's equatorial plane.
<h3>What is the SDH test?</h3>
- Oxidative cell stains are dark for the SDH test and light for the metaphase test.
- SDH is an enzyme used in testing mainly to detect hepatocellular injury in cattle and horses.
- SDH enzyme is also detected in human tissues. The major sites where the SDH enzymes are found in humans are kidneys, seminal vesicles and kidneys.

Answer:
This question describes a PROTEIN
Explanation:
Proteins are one of the four biological molecules in living systems. It is a biological polymer composed of monomeric units called amino acids, which are chemically joined together by peptide bonds.
An amino acid structurally consists of a central carbon atom bonded to an hydrogen atom, carboxylic acid group (-COOH), an amine group (-NH2) and a R side chain, which distinguishes one amino acid from another. Since all amino acids have a nitrogen-containing amine group, all proteins also contains nitrogen in their structure. Hence, a protein consist of an hydrocarbon (CHO) with a nitrogen atom.
Answer: The bacteria uses the oxygen present in the mouth.
Explanation:
The plaque that is formed in the teeth is a highly anaerobic bacteria but it can sustain in the environment rich in oxygen. The oxygen is used by the bacteria and there is a absence of oxygen in the teeth.
It is formed in between the teeth which needs oxygen to survive and if remains for tooth for a longer period of time then it began to grow without oxygen.
It basically uses the oxygen available in the mouth and makes the condition anaerobic.
