<h3><u>Answer;</u></h3>
756 mm Hg
<h3><u>Explanation;</u></h3>
- Intrapleural pressure is the pressure of the air within the pleural cavity, between the visceral and parietal pleurae. This pressure changes during different phases of breathing.
- <em><u>Due to certain characteristics of the lungs, the intrapleural pressure is always lower than, or negative to, the intra-alveolar pressure. It remains approximately –4 mm Hg throughout the breathing cycle.</u></em>
- <em><u>Therefore; if the intrapulmonary pressure was 760 mm hg then the intrapleural pressure will be (760 -4) mm Hg, that is 756 mm Hg</u></em>
B, because they can only see shapes.
Answer: B. 0.77
Explanation:
We should note that from the Hardy-Weinberg law, the formula used is:
p²+ 2pq+ q² = 1
From the information given,
p = purple allele
q = red allele
q² = 59/100 = 0.59
Then, the frequency of the red allele that is recessive will be:
q² = 0.59
q= √0.59
q = 0.768.
q = 0.77
Therefore, the correct option is B.
Answer: a. rna interference.
Rna interference <span> was known by other
names like <span>co-suppression because
it </span>has become evident that RNAi has immense potential in inhibiting desired
genes by neutralizing targeted mRNA molecules</span> Two types of small ribonucleic acid (RNA) molecules that are central to RNA interference
are miRNA and <span>siRNA. </span>
