Answer:
Almost every cell? in our body contains our DNA?.
On average, about 99.9 per cent of the DNA between two humans is the same.
The remaining percentage is what makes us unique (unless you are an identical twin!).
Although this might sound like a small amount, it means that there are around three million base pairs? that are different between two people. These differences can be compared and used to help distinguish you from someone else.
Minisatellites are short sequences (10-60 base pairs long) of repetitive DNA that show greater variation? from one person to the next than other parts of the genome?. This variation is exhibited in the number of repeated units or ‘stutters’ in the minisatellite sequence.

Answer:
(a). 4
(b). 1 triple bond.
(c). 1
(d). 1 ring.
Explanation:
Without mincing words let's get started. So, we have that the chemical formula for the compound is C8H10. So, we are given from the question that lindlar's catalysts which is represented by H2 / Pd / CaCO3 and used in hydrogenation especially from alkyne to alkene.
(a). The degrees of unsaturation in the unknown can be calculated as;
[ (2 × Number of carbon atoms) + (2 ) - (number of Nitrogen atoms) - (number of hydrogen atoms) - number of halogens) ÷ 2
= [(2 × 8) + 2 - 0 - 10 - 0 ] ÷ 2.
=( 16 + 2 -10 ) ÷ 2.
= ( 18 - 10) ÷ 2 = 8/2 = 4.
(b). The number of triple bonds is 1 because we are given from the question that "On catalytic hydrogenation over the Lindlar catalyst, 1 equivalent of hydrogen is absorbed" and this is the work of the catalyst to prevent the alkyne from going to alkane straight.
(c). The number of double bonds is 1 because we are given from the question that "On hydrogenation over a palladium catalyst, 3 equivalents of H2 are absorbed".
(d)The number of rings is 1
Hi there! All of the water returns to the atmosphere, it's called evapotranspiration and condenses. And then the water falls back to the Earth's surface and starts the cycle all over again. If you don't know what I mean, it's the Water Cycle.
