Mucus would most likely accumulate in the respiratory tract as a result of ciliary destruction.

Pertussis (whooping cough) is a highly contagious respiratory tract infection. A severe hacking cough is followed by the a high-pitched breath intake that sounds like "whoop" in many people. Before the vaccine, whooping cough was thought to be a childhood disease. Whooping cough now primarily affects children who have not received the full course of vaccinations, as well as teenagers and adults whose immunity has waned.

Deaths from whooping cough are uncommon, but most commonly occur in infants. That is why it is critical for pregnant women and others who will have close contact with an infant to be immunized against whooping cough. The best way to avoid pertussis is to get vaccinated. Check that you and your loved ones have received their pertussis vaccines.

Radda [10]

Answer:

When there are 5 molecules of fructose on each side of the membrane.

Explanation:

The solution will reach equilibrium fro fructose when there are 5 molecules of fructose on each side of the membrane.

A membranous system is said to be at equilibrium when there are equal concentration of a particular molecule on both sides of the membrane.

<em>Hence, for a membranous system with 10 molecules of fructose on one side, an equilibrium can only be reached for fructose when there are 5 molecules on one side and the remaining 5 molecules on the other side. </em>

VMariaS [17]

Examples of allele types are HH. That is option 2.

<h3>Gene Allele </h3>

An allele in genetic studies is an alternative gene form that is located at a particular point of the chromosome. It is usually represented with capital and small letter of the same alphabet.

There are two types of a allele which include:

  • Dominant allele: This is when the variation seen in a gene produces a noticeable phenotype. This is seen in the gene combination of HH.

  • Recessive allele: This type of allele does not produce any visible noticeable phenotype. This is seen in hh.

Therefore, examples of allele types are HH
