Answer: The following statements comparing respiration in fish and in mammals is correct:

The movement of the respiratory medium in mammals is bidirectional, but in fish it is unidirectional.

Explanation:

Breathing is the process by which living beings exchange gases with the external environment. It consists of the entry of oxygen into the body of a living being and the exit of carbon dioxide from it .

Active ventilation occurs if the animal produces the currents (of air or water) that flow to and from its respiratory membranes. It can be :

Unidirectional. (air or water is pumped onto the respiratory membrane in only one direction).
Bidirectional. (air or water is transported to the respiratory membrane and moves away from it through the same route like in the mammals).

uranmaximum [27]

Streptococcus is a genus of coccus (spherical) Gram-positive bacteria belonging to the phylum Firmicutes[3] and the order Lactobacillales (lactic acid bacteria). Cell division in this genus occurs along a single axis in these bacteria, thus they grow in chains or pairs, hence the nameâ€”from Greekstreptos, meaning easily bent or twisted, like a chain (twisted chain). Contrast this with staphylococci, which divide along multiple axes and generate grape-like clusters of cells.)
