About 25 of the 92 natural elements are essential to life.
Answer:
The correct answer is electromagnetism
Explanation:
An atom is made up of protons, neutrons, and electrons in which protons and neutrons are present in the nucleus and the nucleus is overall positively charged because protons are positive and neutrons are neutral.
Electrons in the atom are negatively charged particles that revolve around the nucleus. Due to the attraction between the positive charge of the nucleus and negative charge of electrons the atoms remain together in a compound.
Electromagnetic force generates when any charged particles move in a path. So it has both electric and magnetic force and this electromagnetic force holds atoms together in a compound because moving of the electron generates electromagnetic force.
Answer:
A. First incubation at 37 Celsius; second at room temperature
Explanation:
When you are sick for some sort of infection your body will raise your body temperature to kill the infection (bacterias, viruses). 37 C it's normal temperature and those pathogens can easily grow up (very fast). 15 minutes it's enough to promote the bacteria reproduction at 37 C, to decelerate you need to change the temperature (a lower one just to decrease the reproduction rate).
Having a low rate reproduction of bacterias it's fine for your culture media, it will last for more time than a culture media with 37 Celsius all the time.
