<u>Controlling disease in commercial fisheries</u>
Explanation:
Disease outbreaks among fishes reared lead to economic loss to the fish farmers. Optimal conditions of the pond should be maintained to prevent disease spreading.
Control of disease is very challenging because fishes are cultivated in aquaponds at high density which increases direct contact among fishes making way for spread of the disease.
Natural predators will remove infected fish quickly but manual methods are time consuming and not effective.
Various steps which can be followed for prevention of diseases like good water quality, nutrition and sanitation facilities, stocking and storing of fish, recording each detail.
At the same time, disease control can easily be done by reducing the density of the stocks, application of vaccines and antibiotics and other drugs, mechanical administration of drugs, use of probiotics etc.
Bacteria living in a deep ocean vent I think
If one species in the food web ceases to exist, one or more members in the rest of the chain could cease to exist too. A plant or animal doesn't even have to become extinct to affect one of its predators.
Answer:
Through a chemical process called "condensation". The addition of the two molecules typically proceeds in a step-wise fashion to the addition product, usually in equilibrium, and with loss of a water molecule.

The answer is: There will be more mold on the moist slice and still none of the dry slice.
Molds belong to the kingdom Fungi. They are multicellular fungi consisting of multicellular filaments (hyphae). For growth, all molds need moist surface. This is the reason why in Gene's experiment, the only moist slice of bread was moldy. They have short life cycle, so 5 days were enough for molds to cover 50% of moist slice. Extended period of time will allow molds to spread more through moist surface if the surface remain moist.
