Explanation:
Bohr model is able to explain the electromagnetic spectrum produced by different atoms of different elements. This is because an electron around the nucleus of an atom occupies distinct orbital levels around the nucleus and not in between. When an electron absorbs a specific wavelength of electromagnetic spectrum it 'hops' to an upper electron energy level equivalent to this wavelength of radiation. When the atom 'hops' to a lower orbital level it releases ta specific wavelength of radiation that is equivalent to the difference in the energy levels. This was unaccounted for in the Rutherford's planetary model.
The electron cloud model is thought to be an improvement on the Bohr model because it accounts for the Heisenberg Uncertainty Principle which stipulates that it is impossible to ascertain the momentum and location of an electron at the same time (because merely viewing an electron using light -or any kind of radiation - will change its direction and velocity). This model explains the likely position of an electron using probabilistic equations. The electron cloud model can therefore be used to explain bonding between atoms.

Answer:
the answer for this particular question is B
Explanation:
B
Answer: ADP ( adenosine diphosphate) is a lower energy molecule, which is converted to ATP ( adenosine triphosphate) by the addition of one high energy phosphate group.
This is an endergonic process as it requires energy.
ATP thus formed in this reaction is a high energy molecule as it stores large amount of energy, which is present in the phosphoanhydride bond ( formed between phosphate).
The reaction can be written as-
ADP + Pi → ATP
Next step, is to look more into it and explore the evidence.
Plants need to carry out both photosynthesis to get food which the formula is CO2 + 2H2A + photons ==> [CH2O] + 2A + H2O <span>and cellular respiration keeps the plant alive maning its empature and vitals.
hope this helps.
