I would guess, it's because Bohr's layered model correctly explains connections between atoms (i.e. molecules) and radiation, but on the hand quantum mechanics say that electrons are exactly not kept nicely with orbits- they are all over the place.
Niels Bohr in fact based his model on the hydrogen atom. However, I wouldn't say that the Bohr Model can be correctly applied to ANY atom. Whilst it is an excellent approximation it is not truly accurate. Please don't forget that the Bohr Model is just that, a model, and a model is never as accurate as the real thing.
Yes, it is true.
D electrons exist in - This statement is not true about Bohr's model of the atom because Bohr proposed that electrons move in quantized orbits around the nucleus, rather than existing as continuous particles.
It is true that an atom has a nucleus. As for which model of the atom is thought to be true, at the present time we use a model based upon quantum mechanics which differs significantly from the early Rutherford or Bohr atomic models.
Yes it is true. Both of them happening in cells.

True. The model of the atom has evolved significantly since the 1930s, moving from the Bohr model to the quantum mechanical model. The discovery of subatomic particles, such as protons, neutrons, and electrons, led to a more complex understanding of the atom's structure.
Yes, it is true.
Yes, it is.
In the logical sense, sentences must be either true or false and not both. "This sentence is false" cannot be true because that would mean that it is false, and it cannot be both. It also cannot be false because that would mean that it is true, and it cannot be both. Therefore, if it is true or false, then it is both true and false. Therefore it is either neither true nor false or both true and false; therefore, in the logical sense, it is not a sentence. However, it says it is a sentence; therefore, it is lying; therefore, it is false.
true
False
And is used in logical comparison in mathematics. true and true is true. true and false is false. false and true is false. false and false is false.
It is both masculine and feminine. :D
It is true and false. It cannot be proved.
False
true
