  • Damage to the outer ear or middle ear, which transmits sound waves to the inner ear, may result in conductive hearing loss.
  • Conductive hearing loss in broad terms means that the loss of hearing has occurred because the sound waves are unable to reach the inner ear which may result from damage either in the outer ear or in the middle ear.
  • The obstruction of the sound wave in the outer ear can be caused due to infection, extra bone growth or earwax.
  • The obstruction in the passage at the middle ear can be caused due to ear tumor, trauma, perforated eardrum etc.

vlada-n [284]

Answer:

1)

  • frequencies of light-colored mice  ≅ 0.74
  • frequencies of dark-colored mice ≅ 0.26

2)

  • frequencies of light-colored mice ≅ 0.13
  • frequencies of dark-colored mice ≅ 0.87

3)

  • q² = 0.74
  • p² = 0.02
  • 2pq = 0.24      

4)

  • q² = 0.13
  • p² = 0.4
  • 2pq = 0.46

5)

The dark-colored fur seems to have the greatest overall selective advantage

6)

Dark lava, that changed the color of the substrate, from light to dark.

7)

Because to produce dark color, animals from the different regions suffered different mutations that drove them to have almost the same dark fur color. All of the animals are inhabiting dark substrate, which means that this environmental condition is favoring the same phenotype.

8)

To see if the mice population is evolving, you need to take a sample of animals per year, through many years, and analyze if it is changing or not. If the population is evolving, you will notice a change in the allelic and genotypic frequencies over the years, favoring one genotype or the other. If the population is not evolving, the frequencies will keep equal through the years, it will not change.

Explanation:

Due to technical problems, you will find the complete explanation in the attached files.

In a humoral or antibody-mediated immune response, specific B cells are stimulated by Helper T cells to help transform into plas
steposvetlana [31]

Answer:

An important feature that B-cells must have in order to become plasma cells and synthesize antibodies is increased rough endoplasmic reticulum in order to have the surface area needed for antibody production (option A).

Explanation:

The transformation of B cells into plasma cells to produce antibodies is a well known function of lymphocytes related to the immune response. This leads to a series of structural transformations in order to performs their function.

The rough endoplasmic reticulum (RER) has the function of contributing to protein synthesis, in conjunction with the ribosomes that are attached to it and the information of the mRNA.

<em>One of the changes experienced by B cells in their transition to plasma cells is the availability of larger RERs, in preparation for antibody synthesis, formed mostly by proteins</em>.
