Answer : The correct option is, (A) Hund's rule

Explanation :

Hund's rule : It states that the electrons are singly filled first in each orbital having same spin, then only pairing occurs.

Heisenberg  uncertainty principle : It is defined as the position and the momentum both can not be determined simultaneously.

Aufbau principle : It states that the atom or ion that present in the ground state, the lowest energy level will be filled first before occupying the higher levels.

Pauli Exclusion Principle : It states that no two electrons present in an atom or a molecule can have the same set of the four quantum numbers.

Hence, the correct option is, (A) Hund's rule

poizon [28]

excitatory amino acids are the amino acids helps in transformation of neurotransmitters or it helps in transmission of synapsis rapidly in brain of mammal. EAA known to be neurotransmitters for Central nervous system.

Excitatory amino acids count may vary from 50’s to 100’s. They are mostly composed of non-protein- amino acids obtained from algae or fungi.

The possible EAAs are Glutamate (Glu) and Aspartate which act as excitatory neurotransmitters in the brain. They get released from neurons where they induce excitation via metabotropic Glu receptors.  

Both glutamate and aspartate having excitatory effect on neurotransmission whereas Gama-amino butyric acid having inhibitory effect on neurotransmission.

Thus, the statement ‘neurotransmitters are chemical brother of gaba’ is indicating the complementary effect of each other.

Ilia_Sergeevich [38]

Missing question: Z:X = 7:1 A:Z = 2.5:1 A:Z = 2.2:1 Y:X = 11:1.

Answer is:<span> Z:X = 7:1 and Y:X = 11:1.
Law of multiple proportions or Dalton's Law said that the ratios of the masses of the second element which combine with a fixed mass of the first element will be ratios of small whole numbers. 
In this example ratios are whole numbers, A:Z = 2.5 : 1 and A:Z = 2.2 : 1 are not whole number ratios.</span>
