Answer:
The correct answer would be c. The cell has a greater level of structural support.
Phospholipds are the structural units of a cell membrane. They are consist of two components; hydrphobic lipids and hydrophylic polar heads.
They make a bilayer structure in which polar heads are in contact with water and lipid part are embedded within the layer.
- Lipid bilayer gives the rigidity or shape to the cell.
- It isolates the cell from the sorroundings.
- It is semi-permiable in nature and thus prevents or control the movement of substances across the membrane.
- Being liquid in nature, the cytoplasm would have dispersed in the surrounding in absence of cell membrane.
Hence, most appropriate choice would be c. The cell has a greater level of structural support.
Answer:
The correct answer d. one of the atoms sharing electrons is much more electronegative.
Explanation:
If one of the atoms is more electronegative than the others, like the oxygen in the water molecule, it will allow this atom to attract the other's electrons turning itself into a negative pole and turning the others into a positive pole. In the water, oxygen is more electronegative and that's why it becomes the negative part and the hydrogens become the positive.
<u>Complete Question:</u>
You volunteer for a sleep study and the researchers discover that your blood oxygen level drops many times during the night. It is likely that you have
A) sleep-onset insomnia.
B) REM behavior disorder.
C) narcolepsy.
D) sleep apnea.
<u>Correct Option:</u>
It is likely that you have "sleep apnea".
Option: D
<u>Explanation:</u>
Sleep apnea is a disorder which is identified by frequent stoppage and breathing start while sleeping. This is due to extreme relaxation of the throat muscles that hinder the normal breathing mechanism leading to reduced blood oxygen levels (recognized as hypopnea).
Throughout a sleep study, the patient's oxygen level is tracked with a pulse oxymeter connected to the hand, finger as well as other parts of the patient. An individual with SA will get a decreased amount of air in inhalation due to irregular breathing patterns while asleep.
