Answer:

Soap solution functions to dissolve the cell membranes, alcohol is used to precipitate DNA, and Gatorade is a isotonic solution.

Explanation:

In the DNA extraction protocols, the cell membranes that are formed by lipidic bilayers can be dissolved by using detergent solutions that are functionally analog to soap solution, shampoo, etc. On the other hand, alcohol enables to precipitate DNA (because DNA is not soluble in alcohol), while proteins and other cellular components remain in the extraction solution. Finally, Gatorade is a isotonic solution that may be used to prevent the cells from lysing.

During which phase of the cell is a cells DNA copied
MakcuM [25]

Explanation:

Hi there!

Cell cycle has 2 phases (i.e M-phase and Inter-phase). Interphase is considered to be the longest phase. Interphase also has G1-phase, S-phase and G2-phase. In cell cycle while moving from M-phase it has two option either to go in G1-phase or G0 phase. It it goes to G0-phase it doesn't go under cell division but if it goes to G1-phase it starts to prepare materials required to replicate or copy DNA. After preparing all the material it goes in S-phase and copies DNA. It doesn't go to G2-phase until it copies DNA perfectly. Then it goes to G2-phase. In this phase it prepares material for replication of other cell organelles.

Therefore, DNA is copied in S-phase.

Hope it helps!

If our muscles didn’t generate opposing forces, in what specific ways would that limit us?
shusha [124]

If muscles did not generate opposing forces, then the contraction and relaxation of muscles leading to movement will be limited.

Explanation:

Basically skeletal muscles work in pairs of agonist and antagonist muscles which work together but with opposing forces to contract and relax respectively. These opposing forces help to facilitate movement. Like in a bicep curl, the biceps work as agonist and triceps work as antagonist. The muscular strength is the force that acts against the opposing force of muscles. This strength is regardless of age, sex, weight or size of an individual.
