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.
Because Stem Cells are more versatile and can be grown into a more variety of tissues, unlike adult cells.
My best guest is probably C or A.
Answer: Mineralization
Explanation: Phosphorous cycle moves through the rocks, water, soil, sediments and organisms.
The weathering of rock releases phosphate ions and other minerals. Plants take up the phosphate from the soil. Phosphorous is present in the form of organic phosphate which is broken down by the help of microorganism in the form of inorganic phosphate.
This process is known as mineralization.
