Answer: The atomic number is the number of protons in an atom, and isotopes have the same atomic number but differ in the number of neutrons. The number of protons in an atom is called its atomic number. This number is very important because it is unique for atoms of a given element. All atoms of an element have the same number of protons, and every element has a different number of protons in its atoms.
Explanation:
Answer:
False.
Explanation:
Up regulation involves the increase of receptors and it makes the cells more sensitive to the hormones.It's the down regulation that involves the loss of receptors and prevents the target cells from overreacting to persistently high hormone levels.

To solve this problem we will apply the Newtonian concept of gravitational acceleration produced by a planet. This relationship is given by:
Where,
G = Gravitational Universal Constant
M = Mass of Earth
r = Radius
The values given are based on the constants of the earth, so they can be expressed as
The relationship of gravity would then be given:
The relationship with the new planet, from the gravity of the earth would be given
The relationship with the weight of the earth would be given as:
Therefore the weigh on this planet would be 96N
Answer:
Natural frequencies of oscillation and typical earthquake frequencies should be different.
Damping on the structure should be large.
Explanation:
The natural frequency of the structure must be different from the typical earthquake frequency, the more different the better. This is because if both frequencies were the same or similar there is a risk that the building will <u>resonate </u>and collapse.
As for the damping, it must have a high value. This so that the building resists earthquakes better and prevents it from moving dangerously, thus damping on the structure should be large.
