Oxygen that is dissolved in the water crossed ghe gill menbrane by diffusion. The oxygen is dissolved in the water like carbon dioxide in a beer. This oxygen is not a part of the water molecule. The oxygen in the water molecule is not available to the fish, when dosolved oxygen gets low, yhou have a fish kill.

Fish can extract oxygen from water using what?

Fish have lamellae in their gills. As the water flows through the gills and over the lamellae, the oxygen is extracted from the water.


How does the thickness of lamellae affect the oxygen uptake by a fish's gills?

Thicker lamellae allow for a larger surface area for oxygen exchange to occur, leading to increased oxygen uptake by a fish's gills. This is important for efficient respiration and meeting the oxygen demands of the fish's body. Thinner lamellae would result in a smaller surface area and potentially limit the fish's capacity to extract oxygen from the water.


What is produced when a compound is heated?

Your question is invalid, your question should be What is separated when a compound is heated, because heating a substance is basically adding energy to it. and the energy is likely to separate compounds. For example when you add electricity(energy) to water it will separate water into oxygen and hydrogen. It will also apply for heat energy, If you add enough heat to separate the bond of water.


How do fish get oxygen from under water?

Fish gills contain rows upon rows of lamellae, which are thin, disc-like membranes loaded with a capillary network. The water flows across the lamellae, and oxygen and carbon dioxide are exchanged directly across the capillary membrane. Humans have similar capillary interchange sites in the lungs, and the gas exchange occurs in much the same fashion, only the fluid from which we get our oxygen is air, whereas fish get their (dissolved) oxygen from the water.


What kind of energy is used when water decomposes?

To separate water into hydrogen and oxygen, electrolysis is usually used; this uses electrical energy. Of course, the electrical energy can be generated in any of several ways.


Would it be easier to separate the sugar from the water or to split water into hydrogen and oxygen?

It is easier to separate sugar from water through physical processes like evaporation or filtration. Splitting water into hydrogen and oxygen requires a chemical process called electrolysis, which typically involves passing an electric current through water, making it more complex and energy-intensive compared to separating sugar from water.


What do the alveoli of the lungs the microvilli and villi in the intestine and the gill lamellae in fishes gills have in common?

The microvilli and villi in the intestine increase the absorbent surface where nutrients are transported into the blood. The alveoli in the lungs and gill lamellae bring oxygen in the air and water to the bloodstream,


What is used to separate hydrogen and oxygen?

Electrolysis is commonly used to separate hydrogen and oxygen. In this process, an electric current is passed through water, causing it to split into hydrogen and oxygen gases.


Which of these best describes the formation of the lowest energy state of water?

The lowest energy state of water is achieved when the hydrogen atoms are covalently bonded to the oxygen atom through shared electrons. This bond formation releases energy, resulting in a stable water molecule with a bent shape and a lower potential energy compared to the separate hydrogen and oxygen atoms.


Fish breathe oxygen which is dissolved in water what kind of solution?

Fish breathe through their gills, extracting dissolved oxygen from water. This process is possible due to the fish having specialized structures in their gills called lamellae, which increase the surface area for gas exchange. The oxygen in water is in the form of a solution, specifically a solution of oxygen gas in water.


How does the electron chain transfer light energy in photosynthesis?

Light breaks down water into hydrogen and oxygen, the oxygen is then released. Next the hydrogen and its electron separate so that they are H+ and e-. The electrons are dragged across which creates massive energy.


Can water be used to separate hydrogen and oxygen?

yes
