Rearrange the following events starting from the formation of the zygote in Marchantia :
I. Formation of sporophyte
II. Spore germination
III. Formation of gametophyte
IV. Gamete formation
V. Reductional division
VI. Formation of spores
VII. Syngamy

Given below is a randomly arranged list of events that occur at the neuromuscular junction to trigger muscle contraction.Which of the following gives the correct sequence of these steps?

(i) Acetylcholine binds to the receptor sites on sarcolemma

(ii) Nerve impulse

(iii) Release of Ca+2 from sarcoplasmic reticulum

(iv) The neurotransmitter acetylcholine is released

(v) Sarcomere shortens

(vi) Acetylcholine diffuses across the synaptic cleft

(vii) Spread of impulses over sarcolemma on T-tubules

Match Column A appropriately with Column B.
