you are given the mass of an element, you use the periodic table to find its molar mass, and multiply the given mass by the reciprocal of the molar mass. This is Mass → Moles . Once you have moles, multiply by Avogadro's number to calculate the number of atoms. This is Moles → Atoms
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.
The answer is a Roman numeral.
Ex:
1: I
2: II
3: III
4: IV
5: V
6: VI
7: VII
8: VIII
9: IX
10: X
Answer:
Correct answer is A, they regulated the ticking of the clock...
Explanation:
The atomic clock uses a more fundamental vibration, and it uses it as part of a self-regulating system. A crystal of quartz has two properties that help it keep time.
The atoms serve the same purpose as did pendulums or quartz crystals in earlier clocks. They have no “hands” to turn or liquid crystal displays for number read-outs. They simply produce electrical pulses that serve as a standard for calibrating other less accurate clocks.
