The cell membrane separates the intracellular environment from the extracellular environment outside of the cell. A phospholipid is composed of a phosphate group and a lipid. It is composed of a hydrophilic, polar phosphate head and two hydrophobic fatty acid tails.
The structure of the bilayer is such that the tails are shielded from contact with water, creating a selectively-permeable barrier which will be impermeable to most hydrophilic molecules.
So, the answer is A) To maintain balance of water and nutrients in the cell.
<span>About 2 weeks.
Since the species isn't mentioned, I will assume human.
Definitions
Colostrum: This is the fluid expressed by the breasts just prior to and for a few days after giving birth. It contains a much higher concentration of nutrients in an easier to digest form than regular breast milk. This type of breast milk will be produced for 2 to 4 days after giving birth.
Transitional Milk: This is a thick creamy milk that contains more fat, lactose, vitamins and calories than colostrum. It starts within 4 days of giving birth and lasts approximately 2 weeks.
Mature Milk: This is a thinner milk that's about 90% water and 10% nutrients. It starts about 2 weeks after giving birth.
So the answer is about 2 weeks.</span>
The recommended guideline for determining suction catheter depth when suctioning an endotracheal tube is;
<u><em>By using a suction catheter with centimeter increments on it.</em></u>
<u><em>Insert the suction catheter into the endotracheal tube until the centimeter markings on both the endotracheal tube and catheter align</em></u>
<u><em>Insert the suction catheter no further than an additional 1 cm.</em></u>
<u><em /></u>
From documented guidelines to determine suction catheter depth, they are;
1) Get a suction catheter with centimeter increments on it.
2) Then you will Insert the suction catheter into the endotracheal tube till the centimeter markings located on both the endotracheal tube and catheter align
3) Next is to insert the suction catheter not more than an extra 1 cm.
4) The length of the endotracheal tube should be combined with any other adapter you are using after which you add an additional 1 cm.
5) Get a spare <em>endotracheal tube</em> that has same size as that being used for the patient.
6) Insert the suction catheter to the end of this tube and take note of the length at which the catheter got to the end of the tube.
7) If you are dealing with a closed system, then all you need to do is to combine the endotracheal tube length and length of additional adapters you are using and add an extra 1 cm.

Answer:
Explanation:
The closed metal container will get distorted or compressed due to a combination of two reasons:
1.<em> contraction of the metal container as a result of a reduction in its temperature.</em>
2. <em>a reduction in the pressure inside the container caused by a sudden drop in the temperature of the water inside it. </em>
The tap water causes a reduction in the temperature of both the container and the water inside it. An increase in temperature causes metal to expand and a reduction in temperature causes it to contract. Also, water takes less space than steam. Therefore, a reduction in the temperature of the hot water causes a reduction in the pressure inside the container relative to the outside. This causes the metal container to be compressed.
