Emphysema is a kind of chronic obstructive pulmonary disease or COPD that which involves physiological abnormalities which includes loss of lung elasticity and air sac enlargement. It all starts when the alveoli or the air sac at the end of the bronchioles becomes enlarged due to its walls breaking down or are destroyed, collapsed, narrowed, stretched or over-inflated. Because of this, there will be fewer and larger damaged sacs which would eventually result to a reduced oxygen and carbon dioxide exchange in the surface area of the lungs. This would lead to a medical condition termed as respiratory acidosis because the lungs are incapable of removing enough carbon dioxide produced by the body.
Therefore, the answer is letter C. CHRONIC RESPIRATORY ACIDOSIS.

PilotLPTM [1.2K]

Answer:

The ear length will be 11 cm.

Explanation:

To know about the ear length of F1 generation, we need to know that how much length in centimeters is contributed by each of the alleles. As we know, each allele has the same value for contributing to the effect of ear length, hence we can divide the ear length by 4 to get our results.

As 6 divided by 4 is 1.5 hence, the allele a and b contribute to 1.5 cm of the length of the ear.

6 divided by 4 is 4, hence the alleles And B contribute to 4 cm of the length of the ear.

The F1 generation will have AaBb genotype hence, the lenght will be 4+1.5+4+1.5 = 11 cm.
