Answer:
D. Separate ecosystems can affect each other.
Polymerization would be the answer you're looking for.
The correct answer is Soluble phosphorous
Soluble phosphorus is a measure of orthophosphate (PO4), the
soluble and inorganic filterable fraction of phosphorus, which is the most
stable type of phosphate and it is the form directly used up by the plant
cells.
From the options what can be said about this disease is that ( B ) : The Pathogen replicates without using host cells' replication machinery and it is directly transmitted.
Since The new disease transmits from one person to another via handshake that means that the disease is a directly transmitted disease, also given that the disease can be cured with the use of antibiotics shows that the causative agent is not a virus but a bacteria. bacteria are living organisms with their own machinery for self replication, therefore they do not need the host cell to replicate the disease before transmission.
Hence we can conclude that the disease is caused by a Pathogen which replicates without using host cells' replication machinery and it is directly transmitted.
