The answer would be: right occiput anterior (ROA)
Presentation of fetus determines which part of their body that will be delivered first. Some presentation will have bigger surface area than others which could complicate the process of the labor. In this case, the baby back in on the right <span>between the midline and lateral surface of the abdomen, so the occipital area should be at the anterior of the pelvis.</span>
Answer:
The enveloped viruses are resistant to disinfectants.
Explanation:
The outer covering or the envelope in the virus comes from the infected cell. This envelope is formed by the process called as budding off, from the host cell. The envelope that covers the virus provides resistance to various disinfectants and prevent virus from damage. The outer coat (envelope) is formed of a small part of cell membrane.
The virus that lyses and kills the cell immediately is less worse than the enveloped virus. The virus that kills cells immediately prevents the host cell from continuously synthesizing new virus particles. Thus, no more viral particles can be produced by the host cell. So, envelope viruses are worse that viruses that directly kills the host cell.
Answer:
Option C, Intrapleural pressure is less than intrapulmonary pressure
Explanation:
During inspiration, the air enters the lungs due to lower pressure in the intrapulmonary or intra-alveolar than the atmospheric pressure. During quite respiration, the intrapulmonary pressure reduces to a pressure that is 3 mm Hg lower than that of atmospheric pressure. During quiet expiration, the intrapulmonary pressure rises up to a pressure that is 3 mm Hg higher than that of atmospheric pressure. This leads to lack of air in the intrapleural space thereby producing intrapleural pressure which is lesser than that of intrapulmonary pressure.
This difference in pressure (i.e higher pressure with in the lungs than the atmosphere) causes lungs to remain attached to the chest wall and hence looks inflated.
Hence, option C is correct
3: B Nervous system. 4: A Sensing and responding to its external environment.
