What functional feature(s) does the phosphate group contribute to the structure of a phospholipid? select all that apply. select
all that apply. place to attach fatty acids?
1 answer:
A phospholipid structure is shown in the picture attached. It has three parts: the hydrophobic tail, the hydrophilic head and the phosphate group in the center. Thus, the function of the phosphate group is to link the hydrophobic and hydrophilic parts of a phospholipid. Specifically, the phosphate group is part of the hydrophilic head. So, it is used to connect the phospholipids to polar compounds.

Answer:
0.7457 g is the mass of the helium gas.
Explanation:
Given:
Pressure = 3.04 atm
Temperature = 25.0 °C
The conversion of T( °C) to T(K) is shown below:
T(K) = T( °C) + 273.15
So,
T₁ = (25.0 + 273.15) K = 298.15 K
Volume = 1.50 L
Using ideal gas equation as:
where,
P is the pressure
V is the volume
n is the number of moles
T is the temperature
R is Gas constant having value = 0.0821 L.atm/K.mol
Applying the equation as:
3.04 atm × 1.50 L = n × 0.0821 L.atm/K.mol × 298.15 K
<u>⇒n = 0.1863 moles</u>
Molar mass of helium = 4.0026 g/mol
The formula for the calculation of moles is shown below:
Thus,
<u>0.7457 g is the mass of the helium gas. </u>
