Phagocytes are cells capable of engulfing and digesting particles or cells harmful to the body. They search for viruses and harmful bacteriae and engulf them. This way they stop disease from spreading. Phagocytes are part of our immune system whose main purpose is to keep us healthy.
Bonjour
C'est la fille de ma mère mais ce n'est pas moi, qui est-ce ?

In the presence of air resistance, a watermelon is launched into the air with 100 j of kinetic energy.
Its kinetic energy is less than 100 J when it reaches its starting point. Its kinetic energy decreases as it encounters air resistance and returns to its starting point. In actuality, some of the energy has been lost because of air resistance. Since we use the ball's original height as a point of reference, there is no potential energy when the ball is in its initial state of motion, and K is its kinetic energy. This total energy is conserved if there is no air resistance, therefore when the ball returns to its starting position, its kinetic energy will remain at 100.

The answer would be Newton’s Second Law
“Yes, because he used energy” is your answer because he made an attempt to move an object.
