Answer:

An axis is an invisible line around which an object rotates, or spins. The object can be a tiny particle, smaller than a single atom. Or it could be a star with the mass of a thousand suns.

Interactions between Na channels and Na -HCO3- cotransporters in the freshwater fish gill MR cell: a model for transepithelial N
Galina-37 [17]

Using intracellular pH (pHi) imaging, we investigated Cl transport mechanisms in freshwater rainbow trout gill mitochondrion-rich (MR) cells. In isolated MR cells, scanning electron microscopy has shown that cellular polarity is maintained.

<h3></h3><h3>What is Transport in Two Species of Freshwater Fish?</h3>

Large amounts of diluted water constantly flow across the gill epithelium of freshwater fish, causing them to experience an ionic stress. Since the mechanisms of ion and acid-base transport are connected at the gill, this is made worse by an acid-base disruption. Active transport at specialised mitochondrion-rich (MR) cells on the gill surface helps the fish maintain homeostasis. As a result, the freshwater gill has served as a crucial model system for figuring out the transport processes that allow for the overriding of adverse ion gradients. Numerous research have tried to clarify the mechanisms of ion and acid-base transport in freshwater fishes during the past ten years using a range of methodologies.

Genetic variation in bacterial populations cannot result from
zmey [24]

Answer:

Meiosis

Explanation:

Gene recombination refers to the mixture of genes from different individuals that occurs during sexual reproduction. Gene recombination is responsible for mixing between genes, which results in genetic variation in a bacterial population.

Genetic variability in a bacterial population occurs through three types of mechanisms: transformation, conjugation and transduction. However this genetic variation does not occur through Meiosis.

Transformation is the incorporation of free DNA by the bacterial cell. Conjugation is the process of transferring DNA from one bacterium to another, involving contact between the two cells. Transduction is the transfer of genetic material between cells, mediated by bacteriophages.
