In an atom, why are electrons in different places and not together?

1 answer:

8 0

Because the charge of electrons is opposite in sign than protons, the two types of particles attract each other, and this force, known as the Coulomb force, holds the atom together. Electrons travel around the nucleus in orbitals, but it is impossible to know both the speed and location of an electron at the same time.:) let me know if this helped

Solar Energy is best option of Coal power plant. It is safe as well as very minimal impact on environment.

Explanation:

Solar energy is one of the best ways to build an energy. It uses captured sunlight and create photovoltaic power or “concentrated solar power” for solar heating. The use of solar power is increasing day by day.

Now subway, buses, college, institute all use solar energy for their electricity consumption. Recently solar powered aircraft whose name is impulse2 is made. Because of zero emission of carbon dioxide government move towards this option.

Disadvantage: It is very costly and takes more space for installation

Where in the cell cycle is dna polymerase most active? click the correct box?

astraxan [27]

The correct question with the options would be:

During which part of the cell cycle is DNA polymerase most active?

a. G1 phase of interphase

b. mitosis

c. S phase of interphase

d. G2 phase of interphase

e. cytokinesis

The correct answer is c. S phase of interphase.

The replication of the entire genome or the whole DNA occurs during the S-phase or also called synthesis phase. Therefore, the enzyme is DNA polymerase which carries out the replication of DNA shows its maximum activity. The DNA polymerase is active in various cell cycle checkpoints to detect the DNA damage but the repair action of DNA polymerase involves only a small region of DNA as compared to the whole genome during the S-phase.
