Answer:
óxido ácido y óxido básico
Explanation:
Los óxidos son compuestos químicos formados por la combinación de un elemento químico con el oxígeno (O). Si el elemento que se combina es un metal, el óxido formado se denomina óxido básico. Por el contrario, si el elemento que se combina es un no metal, el óxido resultante es un óxido ácido.
Se (Selenio) es un elemento no metálico, por lo que su óxido (SeO) es un óxido ácido.
Hg (Mercurio) es un elemento metálico, por lo que su óxido (HgO) es un óxido básico.

SEM and TEM are electron microscopes whereas the SEM uses reflected electrons and TEM uses transmitted electrons to form an image
Explanation:
- SEM is the scanning electron microscopes and TEM is the Transmission electron microscope
- SEM works by detecting the scattered electrons to create an image of the sample whereas the TEM detects the transmitted electrons to create the image of the sample
- SEM will only be analysing the surface of the sample whereas TEM collects data vertically also
- TEM sample needs to cut thinner than SEM and TEM will give high-resolution images than SEM

<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.
