Hershey and chase performed an experiment in order to determine how bacteriophages infect bacteria and discovered that DNA is the genetic material.
<h3>
What is DNA?</h3>
This is referred to as deoxyribonucleic acid and is the genetic material of living organisms .
Hershey and chase performed an experiment using bacteriophages which contains protein and DNA by infecting it with bacteria and it was observed that DNA enters the host bacterial cell, but most of their protein does not.
This therefore means that DNA is regarded as the hereditary material.

You have to remember Chargaff's rule which is pretty simple:
A always pairs with T; G always pairs with C
So look at your table.
Human: you know 2 numbers: G is 19.9 and T is 29.4. By Chargaff's rule you can fill in the other 2 so you'd have:
A (29.4), G (19.9), T (29.4), C (19.9)
I'll skip to the last one on the bacterium:
Here you only know one. But, you really know 2:
A is 13.4 so T must also be 13.4. This adds up to 26.8.
100-26.8= 73.2 (which is the amount of G+C); so divide this by 2 and you get 36.6 - so 36.6 G and 36.6 C!
Just remember who pairs with who...will never let you down!

Answer:
Water has cohesive and adhesive properties.
Water molecules have strong cohesive forces due to their ability to form hydrogen bonds with one another. Cohesive forces are responsible for surface tension, the tendency of a liquid's surface to resist rupture when placed under tension or stress.
