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.

lord [1]

Answer:

Plus end and kinesin.

Explanation:

Three important cytoskeleton components are microtubules, microfilaments and intermediate filaments. Microtubules are the polymer of tubulin and plays an important role in the movement of cell organelles and its structure.

Microtubules shows the process of polymerization and depolymerization at different ends. The plus end shows the polymerization and minus end shows the depolymerization process. The kinesin protein is required for the process of polymerization.

Thus, the correct answer is option (D).

Throughout the lifespan, we change physically, cognitively, and psychosocially. This illustrates the notion that development is
gayaneshka [121]

Answer:

multidimensional

Explanation:

Development is multidimensional

By multidimensionality, we mean a complex and dynamic interaction of factors that control development all through the lifespan, it as to do it biological, cognitive, and socioemotional changes.

Let's take for instance, in adolescence, puberty comprises of physiological and physical variations with variations in hormone levels, the formation of primary and secondary sex characteristics, changes in height and weight, and varying other bodily alterations. The cognitive changes (increment in thinking- abstractly), emotional and social changes (controlling emotions and relationships with equals, falling in love).

Puberty deals with a wide range of domains that exemplifies the multidimensionality component of development.

What determines the color of soil
shutvik [7]

Answer:

Actually, the main pigmenting (coloring) agents in soils are organic matter, iron, and, to a lesser extent, manganese. When these agents are not covering the mineral grains, the natural color of the grains is visible. Colour is a simple method of classifying soil. Black/dark brown soil usually indicates the presence of decaying organic matter so is generally fertile. Pale brown/yellow soil often indicates that organic matter and nutrients are low and this generally means poor fertility and structure.he colour of the soil varies from one place to the other because soil is formed out of different types of rock . Since rocks are of different colours and textures , the colour of the soil varies from one place to another .
