By blocking the UV rays that are emitted by the sun.

The ozone layer helps to sustain terrestrial life by;

Absorbing incoming UV radiation

Keeping levels of ozone in the troposphere low

And, maintaining the Earth's temperature structure

The absorption of ultraviolet light by ozone creates a heat source that forms the stratosphere (a region where temperature increases with altitude).

It plays a decisive role in the structure of the Earth's atmosphere temperature. It is characterized by a concentration of ozone, proportionally greater than in the other layers of the atmosphere, of the order of ten parts per million.

force is mass*acceleration.

we have a very small mass: 11.4*0.001 kg

if we want 0.035n of force, we need an acceleration:

0.035 = 11.4*0.001*a

a = 0.035/(11.4*0.001) m/s^2

the skeletons of most mammals reach a certain size and then stop growing. however, many animals, including some mammals, keep growing throughout their lives. kangaroos, for example, just keep growing and growing until they die. also, the longer an animal lives the greater the chance it might catch some deadly disease.
