2)
it’s charge would increase by -1
Explanation:
The type of atoms is usually determined by the number of protons. Different isotopes of an atom differ in the number of neutrons only. The number of electrons, however, in neutral atoms is the same as that of the protons. Its charge is zero because the positive charge of the protons cancels out with the negative of the electrons. Adding an electron to a neutral atom, therefore, increases the negative charge of the atom by 1
Answer:
The correct option is A. Diffusion
Explanation:
Diffusion can be described as a mechanism through which molecules move along the concentration gradient i.e from an area of higher concentration to an area of lower concentration. This process does not require energy as the molecules or ions move along the concentration gradient.
Hence, the pumping excess sodium ions by the cell membrane to an area where the concentration of sodium is less would be an example of diffusion.
Towards the poles because its far from the equator.
This happens when the temperature of air is increased. Warm air molecules have more energy, so they move faster and create more pressure. ... So, you can see that density, temperature and pressure work together to change the conditions of the air. When heat is added, air temperature and pressure both increase.
