Answer:
The correct option for question 1 would be:
a bilayer containing lipids with hydrophilic head groups pointing inward and hydrophobic tail groups facing the solvent (extracellular fluid and cytosol).
The correct option for question number two would be: proteins.
Explanation:
The membranes present phospholipids that act as selective barriers between the intracellular and extracellular space, allowing an internal balance in relation to the external one.
Its conformation is mostly phospholipids, fatty acids, proteins (from transmembrane to intermembrane or external)
Im pretty sure it would be a total of 13
I am pretty sure the answer is D. That the patterns of a polarity matched up on both sides.
Answer:
V₂ = 123.6 L
Explanation:
According to Boyle's law pressure and volume of a gas are inversely related if amount and temperature are kept constant. For the initial and final states the gas law is given as,
P₁ V₁ = P₂ V₂ ----- (1)
Data Given;
P₁ = 103 kPa
V₁ = 30 L
P₂ = 25 kPa
V₂ = ?
Solution:
Solving equation 1 for V₂,
V₂ = P₁ V₁ / P₂
Putting values,
V₂ = (103 kPa × 30 L) ÷ 25 kPa
V₂ = 123.6 L
Result:
As the pressure is decreased from 103 kPa to 25 kPa, therefore, volume has increased from 30 L to 123.6 L.
It is compressed so that the volume is reduced making it easier to transport via gas tanks. However, it must not be exposed to high temperature because the pressure inside the tank will increase more than the tank can hold resulting to explosions. The gas has to be decompressed to atmospheric before it can be inhaled.
