The correct answer to my knowledge would be 45.
Assuming that the 10 soils are each represented by A, B, C, D, E, F, G, H, I, J.
A can combine with 9 others as: AB AC AD AE A F AG AH AI AJ
B can combine as: BC BD BE BF BG BH BI BJ
C as: CD CE CF CG CH CI CJ
D as: DE DF DG DH DI DJ
E as: EF EG EH EI EJ
F as: FG FH FI FJ
G as: GH GI GJ
H as: HI HJ
I as: IJ
Once you add all the combinations together, you get 45.
Hoping this helped you!
Answer:
<h2>c. Migration distance on a gel is inversely proportional to DNA fragment size </h2>
Explanation:
- Deoxyribonucleic acid is a genetic material that is a type of macromolecule.
- It is made up of a monomer that ais called a nucleotide. Each nucleotide is made up of a deoxyribose sugar, a base, and a phosphate group.
- Due to the presence of phosphate group DNA has negative property. When the DNA is separated by the gel electrophoresis method the size of the fragment of the DNA plays an important role.
- Those DNA fragments that are small in size migrate faster than those DNA fragments that are larger in size.
- So the migration distance is inversely proportional to the DNA fragment size.
I would say the answer is false because they also used information of science to help make things like medicine and fungi and fossils, one of the main things science was used for was chemistry and physics to determine what things could kill humans in the world back in the day.
