Answer:

true

Explanation:

think of a box, if you push it on a smooth floor without friction it would glide pretty easy

but put it on say carpet, the friction from the carpet would not allow the box to move very far

that's also how brakes work, they apply friction to the wheels in order to get them to reduce motion

Which of the following methods brings about cell lysis due to cavitation induced by rapid localized pressure changes?
Inga [223]

Answer:

Sonication.

Explanation:

Sonication may be defined as the process of use of sound energy to agitate the particles in the sample that can be used for the extraction of compounds from the sample. The ultra sonic sounds are used in this process.

The sonication pressure is used for the cell lysis. Sonication causes the cavitation that are induced by the rapid localized pressure changes in the cell. This pressure change causes the breakdown of the cell component.

Thus, the correct answer is option (4).
