Final answer:
The recommended fixative for studying tissue content by micro-incineration is formalin. Formalin is an aqueous solution of formaldehyde, which denatures proteins, kills bacteria, and stops tissue decay. Other chemical fixatives can also be used. Option a.
Step-by-step explanation:
The recommended fixative for studying tissue content by micro-incineration is formalin.
Formalin is an aqueous solution of formaldehyde, which is a strong disinfectant and biocide that denatures proteins, kills bacteria, and stops the biological processes that cause tissue decay. It is used for preserving tissue specimens and embalming bodies.
Other chemical fixatives such as acetic acid, ethanol, methanol, and glutaraldehyde can also be used to stabilize cell structures in tissue samples.Option a.
