How does presence of algae in water result in reduction of oxygen content in water?
Algae can reduce oxygen levels in water through a process called eutrophication. When there is an overgrowth of algae, it can block sunlight from reaching underwater plants, which leads to their death. As dead plants are decomposed by bacteria, oxygen is consumed in the process, resulting in lower oxygen levels in the water.

What do the result of the iodine test indicate about the composition of the endosperm?
The result of the iodine test indicates the presence of starch in the endosperm. When the endosperm is stained blue-black by iodine, it suggests a high starch content. Conversely, if there is little to no staining, it indicates a low starch content in the endosperm.
What happens when the water content of rock increases?
When the water content of rock increases, it can lead to a reduction in the rock's strength and stability, making it more prone to weathering and erosion. The presence of water can also facilitate chemical reactions, altering the mineral composition of the rock. Additionally, increased water content can result in hydrostatic pressure, which may cause physical changes such as fracturing or slumping. Ultimately, this process can significantly impact geological formations and landscapes over time.
Why is carbon reduction method applied in many metallurgical process?
High carbon content causes metals (especially iron) to be brittle. reducing the carbon content in the metals enables them to be more flexible and stronger although it causes them to be softer.
What is a beta reduction?
A beta reduction is an act of beta reducing, an instance of replacing a function call by the result of calling a function.
Name a nonfermentative test in which gas production indicates a positive test result?
The oxidase test is a nonfermentative test in which the presence of gas bubbles indicates a positive result. Gas bubbles result from the reaction of the test reagent with cytochrome c oxidase, which is present in certain bacteria like Pseudomonas species.
Is rust the result of a chemical reactaction?
Yes, rust is the chemical reaction of Oxygen and Iron when there is a presence of water.
Is glucose and oxygen the result of resperatation?
No, glucose and oxygen are the reactants in respiration. During respiration, glucose is broken down in the presence of oxygen to release energy, carbon dioxide, and water.
What As elevation increases oxygen content .?
As elevation increases, the oxygen content in the air decreases. This is because at higher altitudes, the air pressure is lower, leading to less oxygen being available for breathing. This can result in challenges for those not acclimatized to high altitudes.
What do the result of the iodine test indicate about the composition of the endosperm?
The result of the iodine test indicates the presence of starch in the endosperm. When the endosperm is stained blue-black by iodine, it suggests a high starch content. Conversely, if there is little to no staining, it indicates a low starch content in the endosperm.
When a piece of copper is heated in presence of air its weight?
When a piece of copper is heated in the presence of air, it can react with oxygen to form copper oxide. This can result in an increase in weight due to the addition of oxygen atoms from the air to the copper atoms.
Is the presence of air necessary for the formation of rust?
Yes, rust is result of combustion and combustion is burning in air. Consequently it is necessary.
When iron reacts with oxygen what form will it be?
When iron reacts with oxygen in the presence of moisture, it forms iron oxide, specifically rust. Rust is a reddish-brown compound that is a result of the oxidation of iron.
Which pair of substances might be involved in an oxidation-reduction reaction that would result in the formation of ions?
One possible pair of substances that could be involved in an oxidation-reduction reaction to form ions is magnesium and oxygen. In this reaction, magnesium would undergo oxidation to form Mg2+ ions, while oxygen would undergo reduction to form O2- ions.
Why the lime water cannot be determine the presence of oxygen in an organic compound?
Lime water cannot be used to determine the presence of oxygen in an organic compound because lime water reacts with carbon dioxide in the air to form calcium carbonate, which causes the lime water to turn milky. This reaction can give a false positive result for the presence of oxygen in the organic compound, as it is actually detecting the presence of carbon dioxide.
Why does the amount of oxygen in the blood decrease when sleeping?
During sleep, our body's metabolism and oxygen demand decrease. As a result, our breathing rate slows down, leading to a lower intake of oxygen. This reduction in oxygen intake causes a decrease in the amount of oxygen present in the blood.
What is the result on mixing a water molecule and a oxygen molecule together?
When a water molecule and an oxygen molecule are mixed together, they can react to form hydrogen peroxide (H2O2). This reaction typically requires energy input, such as in the presence of a catalyst or under certain conditions.
What elevation increases oxygen content?
It is at sea level. The higher you climb from sea level, to reach the summit of Mount Everest (for example), the less oxygen is in the very thin air. This is why the majority of climbers of Mount Everest have to carry oxygen cylinders. Someone occasionally achieves the summit without oxygen tanks! Therefore, the higher the altitude, the thinner the oxygen in the air.
