The ballistic method of developing flexibility is the safest form of stretching. please select the best answer from the choices
Veseljchak [2.6K]

Answer;

The above statement is false.

The ballistic method of developing flexibility is not the safest form of stretching.

Explanation;

-Ballistic stretching uses the momentum of a moving body or a limb in an attempt to force it beyond its normal range of motion. It involves stretching by bouncing into (or out of) a stretched position, using the stretched muscles as a spring which pulls you out of the stretched position. An example is the ballistic method of touching your toes would be to bounce and move toward your feet.

__________________ dating involves age-dating fossils with known time periods grouped into four eras that represent distinct age
RSB [31]

According to the research, the correct option is Relative dating. It involves age-dating fossils with known time periods grouped into four eras that represent distinct ages in the history of earth.

<h3>What is Relative dating?</h3>

It consists of ordering fossils or events in a proper formation sequence from the oldest to the most modern, it tends to be used as a method for making chronologies, the ordering of events, fossils or rocks.

Since it does not give an exact or approximate date, they can only give us a fairly long period of time, or in their case a temporal ordering of the fossils.

Therefore, we can conclude that according to the research,  the correct option is Relative dating. It involves age-dating fossils with known time periods grouped into four eras that represent distinct ages in the history of earth.

In the lungs, small alveoli are the site of gas exchange where carbon dioxide diffuses into the lungs for exhalation, while oxygen from the air diffuses into the capillaries surrounding the alveoli to be pumped throughout the body.
