The second and third one I believe
Answer: Option A and D.
Soups chemical synaptic transmission.
Sparks direct electrical transmission.
Explanation:
Intercellular communication refers to the communication and interaction that exists between two cells in the body. It could be hormonal or synaptic transmission.
Synapse is the site where electric nerve impulses are transmitted between two nerve impulses.
There are two synapse possibilities which are electrical and chemical.
The Sparks and soups mean that the scientific discovery over the transmission of nerve impulses as to whether they are electrical impulses (Sparks) or chemical impulses(soup).
Chemical synaptic transmission means there is no physical touch in the space chemical are released and move to the neighbouring cells.
Electrical transmission means neuron physically touch and give way for flow of impulses between cells.
Each group of three nucleotides encodes one amino acid. Since there are 64 combinations of 4 nucleotides taken three at a time there are 20 amino acids.
