What organ is able to extract dissolved oxygen from water?
Fish extract dissolved oxygen from water through their gills. The gills are equipped with thin membranes that allow for the exchange of gases, whereby oxygen in water diffuses into the bloodstream and carbon dioxide is released.
Can dissolved oxygen value be a negative value?
No, dissolved oxygen values cannot be negative. Dissolved oxygen levels in water are typically measured in milligrams per liter (mg/L) or parts per million (ppm) and will always be a positive value. Negative values would not make physical sense in this context.
What are two things that photosynthesis make?
Two things that photosynthesis produces is sugar and oxygen.
How does the temperature of water affect the amount of oxygen dissolved in it?
The temperature of water affects the amount of oxygen dissolved in it. Generally, colder water can hold more oxygen compared to warmer water. This is because cold water molecules are closer together, allowing more oxygen molecules to dissolve in the water. Conversely, warmer water molecules are farther apart, making it harder for oxygen to dissolve.
What is biological imortance of air dissolved in water?
The oxygen in air dissolved in water is essential for aquatic organisms to perform respiration. It allows fish and other aquatic life to extract oxygen from the water to survive. Additionally, air in water can also contribute to the regulation of pH levels by buffering acids and bases.
Normal ranges for dissolved oxygen test?
dissolved oxygen is dissolved oxygen
What is the oxygen dissolved in water is a?
The oxygen dissolved in water is a measure of dissolved oxygen (DO).
How can steel rust?
The iron part of steel combines with oxygen in the air, or dissolved in water. This is a chemical reaction, which produces iron oxide- rust.
What's dissolved oxygen?
Dissolved oxygen is the current amount of oxygen in the water. A certain amount of Dissolved Oxygen Is needed to keep the fish alive, if any of the dissolved oxygen decreases by either a little or a lot it can cause changes in the water, normally if the dissolved oxygen decreases so do the fish and aquatics life's life.
What produces most oxygen on earth?
We need to distinguish the oxygen which is a constituent of water and oxygen which is dissolved in water. The former is made in the hearts of stars; the latter is largely released from carbon dioxide by photosynthetic plants.
What is dissolve oxygen?
Dissolved oxygen refers to the amount of oxygen present in water. It is essential for aquatic life to breathe and thrive. Factors such as temperature, water flow, and levels of organic matter can impact the amount of dissolved oxygen in water.
What is oxygen in water called?
Oxygen dissolved in water is typically referred to as dissolved oxygen (DO). The amount of dissolved oxygen is crucial for the survival of aquatic organisms and is influenced by factors such as temperature, pressure, and biological activity.
When hydrochloric acid is dissolved in water the reaction produces carbon dioxide and oxygen?
This statement is incorrect. When hydrochloric acid is dissolved in water, it dissociates into hydrogen ions (H+) and chloride ions (Cl-). There is no production of carbon dioxide and oxygen in this reaction.
Do you breathe water?
We do not breathe in the water as we can't breathe dissolved oxygen.Dissolved oxygen are oxygen that are dissolved into the water.
How does pH affect the levels of dissolved oxygen in a solution?
The pH level of a solution can affect the levels of dissolved oxygen. When the pH is lower (more acidic), the solubility of oxygen decreases, leading to lower levels of dissolved oxygen. Conversely, when the pH is higher (more basic), the solubility of oxygen increases, resulting in higher levels of dissolved oxygen.
What changes the amount of dissolved oxygen in the water?
Factors such as temperature, pressure, salinity, and the presence of organisms can affect the amount of dissolved oxygen in water. For example, higher temperatures typically result in lower dissolved oxygen levels, while photosynthesis by aquatic plants can increase dissolved oxygen through oxygen production.
What is the difference between dissolve oxygen and oxygen?
Dissolved oxygen refers to the oxygen gas that is dissolved in water, which is essential for aquatic life. Oxygen, on the other hand, refers to the gaseous element found in the atmosphere that is necessary for respiration in animals and humans, as well as for combustion.
