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.

Genes A and B are 10 map units apart and genes B and C are 20 map units apart, with gene B located between genes A and C. What w
Marizza181 [45]

Answer:

2% of the progeny will be double crossovers for the trihybrid test cross

Explanation:  

By knowing the positions of genes, we can estimate the distances in MU between them per region.

  • Genes A and B are 10 map units apart (Region I)
  • Genes B and C are 20 map units apart (Region II)
  • Genes A and C are 30 map units apart

----A-------10MU--------B-------------20MU-------------C---

             Region I                      Region II  

We can estimate the recombination frequencies by dividing each distance by 100.

• recombination frequency of A-B region = 10MU / 100 = 0.10

• recombination frequency of B-C region = 20MU / 100 = 0.20

Now that we know the recombination frequencies in each region, we can calculate the expected double recombinant frequency, EDRF, like this:

EDRF = recombination frequency in region I x recombination frequency in region II.

EDRF = 0.10 x 0.20 = 0.02        

2% of the progeny will be double crossovers for the trihybrid test cross

Brut [27]

Explanation:

Vinegar and baking soda have many uses in our society.

Both are obviously used for baking and cooking.

They also as more environmentally friendly, and sometimes more effective, alternatives for certain cleaning products.

A specific example, in a school science classroom setting, they are safe products for a basic lab demonstration for chemical reactions.
