Answer: Option (a) is the correct answer.
Explanation:
A lipid that contains a phosphate group in its molecule is known as a phospholipid.
These are the primary molecules present in a plasma membrane. These tend to contain two hydrophobic fatty acid tails and one hydrophilic head.
Hydrophilic means water loving in nature.
As phosphate group is a polar group due to this the hydrophilic region present in a phospholipid is able to interact with water.
In an amino-alcohol modified phosphate, ester groups, and glycerol, the glycerol is hydrophobic in nature. It also contains two fatty acids and a phosphoric acid which are present as ester. The polar head that mainly consists of phosphate group is hydrophilic and thus, it helps in combining to a water molecules.
Hence, we can conclude that in a phospholipid, amino-alcohol modified phosphate, ester groups, and glycerol are the components which constitute the hydrophilic head.

I hope this answer is correct
The half life of this radioisotope is 12 hours.
<u>Explanation:</u>
The length of time it requires to break down for an initial half amount or the amount of time taken to transform half of a reactant into product. Half of a particular sample took the time to experience radioactive decay. The time it would take to degrade radioactively into another component or nuclide for half of the atoms of an unstable element or nuclide.
If 1/16 of the sample remains it predicts that there were 4 half-life periods then 16 = 2⁴
4 half-life periods = 48 hours / 4
half-life period = 12 hours.
Explanation:
Since scientists think planets and meteorites were made at the same time and in the same place, it seems logical that whatever a meteorite is made of is also what planets are made of.
