The phospholipid head is hydrophilic which means it has an affinity for water. And it is true.
<h3>What is phospholipid , its component and how come it is hydrophilic?</h3>
- Phospholipid contains of a head and a tail , the head part of phospholipid consist of phosphate group and for further clarification the tail part of phospholipid consist of fatty acids.
- As we know already phosphate group that is OH- is negatively charged which clearly which its head is going to be polar .
- Since its polar , its hydrophilic. There is a specific function performed by phosphate group that cannot be filled by other compound present simultaneously.
- Phosphate group grabs a role to provide space to other compounds too.

Explanation:
1 Cal of energy is equivalent to 4.184 Joules.
A.
770Cal of energy = 3221.680 joules
Therefore, 780kCal of energy = 3221680 Joules.
B.
3200000 Joules (in 2 s.f).
C.
I000 joules = 1 kJoule
3221680 joules = 3221.689 kJoules.
D.
3200 kJ (in 2 s.f).
velocity is speed and direction so it should be expressed in mph f/s (feet per second) with a direction like North, right, left,
ex) 5mph south
Answer:
1.806 × 10²⁴ atoms
Explanation:
To obtain the number of atoms a substance contain, we have to multiply the number of moles in that substance (n) by Avogadro's number, which is 6.02 × 10²³.
According to this question, a sample of carbon tetrachloride (CCl4) contains 3 moles of the substance. The number of atoms in CCl4 is calculated thus:
number of atoms = 3 × 6.02 × 10²³
number of atoms = 18.06 × 10²³
number of atoms = 1.806 × 10²⁴ atoms.
Answer:
The charge is +2
Explanation:
Protons are positive, electrons are negative. 10-8=2.
+2 :)
