Answer:
Hydrophobic.
Explanation:
The plasma membrane or cell membrane is made of the lipid bilayer and the proteins are embedded in the this layer. Carbohydrates are also exposed to the cell surface in association with proteins and lipids.
The interior of the cell membrane is hydrophobic due to the arrangement of the lipid bilayer. The hydrophobic part of the lipid membrane are associated with each other that makes the interior of the cell membrane hydrophobic and small molecules easily diffuse through the membrane.
Thus, the correct answer is option (c).
Answer:
The correct answer is D.
Explanation:
Papillary muscles, attached via chordae tendineae, help to close the valves and prevent regurgitation.
Pectinate muscles are parallel ridges in the walls of the atrium of the heart, mainly in right atrium. They can stretch during adverse loading conditions, to <em>help the right atrium to dilate without much wall stres</em>s.
Answer:
The correct answer will be option B.
Explanation:
Blood pressure represents the pressure of the blood in the major arteries of the body.
This blood pressure increases in the arteries when the ventricle contracts to push the blood to the major artery by a mechanism called ventricular systole. This increased blood pressure number is known as systolic blood pressure which is usually 180 mm of Hg.
The blood pressure decrease in the artery due to ventricular diastole during which ventricles relaxes. This lower number of blood pressure is known as diastolic blood pressure which is 80 mm of Hg.
Thus, option B is the correct answer.
Pulse oximetry and ABGs are the two most important tests used to identify hypoxemia and hypercapnia.
<h3>Are ARDS and acute respiratory failure the same thing?</h3>
The term "acute respiratory distress syndrome" refers to the acute hypoxaemic respiratory failure brought on by significant widespread alveolar-capillary membrane destruction (ARDS). Clinically and radiographically, ARDS represents acute pulmonary inflammatory diseases.
To diagnose respiratory conditions including asthma, chronic obstructive pulmonary disease (COPD), and others, spirometry is employed. Spirometry may be used often to check on the effectiveness of a treatment for a chronic lung condition.
The inability to exercise as vigorously as you previously did, extreme tiredness, shortness of breath or the feeling that you aren't receiving enough oxygen, and sleepiness are among the symptoms.

Answer:
Gold is primarily found as the pure, native metal. Sylvanite and calaverite are gold-bearing minerals. Gold is usually found embedded in quartz veins, or placer stream gravel.
