The rigth answer is 14.7N

The law of gravitation thus makes it possible to calculate a force exerted between two objects. In a terrestrial reference system, we can then calculate the force exerted between the Earth and an object.

The law applied in this case is P = mass x g (gravitational constant = 9.8 N / kg)

if a book weighs 1.5 kg then: P = 1.5 x 9.8 = 14.7N

Why don't the hydrolytic enzymes Within lysosomes destroy each other?
Firdavs [7]

Answer:

A lysosome is a membrane-bound cell organelle that contains digestive enzymes.  They break down excess or worn-out cell parts. They may be used to destroy invading viruses and bacteria. If the cell is damaged beyond repair, lysosomes can help it to self-destruct in a process called programmed cell death, or apoptosis.
