Arrange the events of synaptic transmission in correct sequence
(1) sodium ions diffuse into the cell and cause a local potential
(2) neurotransmitter binds with receptor on postsynaptic cell
(3) neurotransmitter diffuses across the synaptic cleft
(4) membrane permeability to sodium ions on postsynaptic cell increases
(5) action potential causes release of neurotransmitter
Answer:
5,3,2,4,1
Explanation:
The firing of an action potential at pre-synaptic neuron makes its axon terminal to release the neurotransmitters in the synaptic cleft. The released neurotransmitter molecules then bind to their receptors present at the surface of the dendrites of the postsynaptic neuron. This binding opens ion channels and allows the specific ions to enter into the postsynaptic neuron. The opening of Na+ channels allows these ions to enter into the neuron and changes the membrane potential. This changed membrane potential is called local potential and is a depolarizing graded potential.
Mendel wants to control the pollination of his pea plants because traits were not blended but they remain separate in the subsequent generations and also it is contrary to scientific opinion during his time
<u>Explanation:</u>
- Mainly, he wants to control because they were against the scientific opinion during his time.
- Mendel takes a pea plant for his experiment because it can be easily observable.
- Pea plant has seven traits and it can be pollinated by both the ways. One is self-pollination and the other is cross-pollination.
- Mendel did not know about the genes but he speculates the factors of formation in the traits.
- Mendel produces three laws, the law of dominance, the law of segregation, the law of independent assortment.
