Answer:
<em>d) Surface tension from pleural fluid and negative pressure in the pleural cavity</em>
Explanation:
Pleural cavity can be described as the space which is present in between the pleura. Pleura can be described as the two thin membranes surround the lungs. These pleural cavity is responsible for holding the lungs to the thorax wall. It aids the functioning of the lungs at the time of breathing. It acts as a lubricant at the time of respiratory movements. Hence, the correct option is d.
Answer:
<h2>approximately 4%</h2>
Explanation:
Given, frequency of recessive allele (p )= 0.02
so, the frequency of dominant allele is (q )= 1-p
so q = 1-p
p = 0.02
q = 1- 0.02
q = 0.98
Once we know p and q, which factor of the Hardy-Weinberg equation. we can calculate percentage of individuals who are carriers of lethal recessive allele.
so
Result : percentage of individuals who are carriers of the lethal recessive allele is 4%.
