What else can I help you with?
What gas do bubbles contain if there is an experiment wether pondweed still has as much photosynthesis underwater?
The bubbles produced by pondweed during photosynthesis underwater contain oxygen gas. This is a byproduct of the process and indicates that photosynthesis is occurring. If the experiment permits the bubbles to escape, they can be collected and tested to confirm the presence of oxygen.
What is tested with the blood work?
Blood work can test for various things including: levels of different blood cells, cholesterol levels, blood glucose levels, kidney and liver function, hormone levels, and presence of certain diseases or infections.
What property of oxygen is made use in this test?
The test likely makes use of the fact that oxygen is essential for combustion. If the material being tested contains oxygen, it will burn in the presence of a flame, aiding in the identification of its components.
What would be a testable hypothesis for an experiment that compares the health of salmon rasised in fish farms to slamon caught in the wild?
The hypothesis could be: "Salmon raised in fish farms will have higher levels of toxins, such as mercury, compared to salmon caught in the wild." This hypothesis can be tested by analyzing the toxin levels in both groups of salmon and comparing the results.
What is IG on blood test?
IG typically stands for Immunoglobulin, which are antibodies produced by the immune system to help fight infections and other invaders in the body. Immunoglobulin levels can be tested in the blood to assess immune system function and detect certain diseases or disorders.
Which liquid is used to test for carbon dioxide?
Carbon dioxide levels are tested through the blood
When did the carbon-oxygen cycle start to change?
In my own opinion and un-tested hypothesis.... that carbon oxygen cycle start to change when there is no more plants to give oxygen and get carbon dioxide and there is no animals and humans that inhale oxygen and give off or exhale carbon dioxide.
Why splint test for carbon dioxide is not good?
The splint test is to test for the presence of oxygen. You light a small piece of wood (the splint), then blow it out. The end of the wood will still glow. If you put the glowing splint into a test tube with oxygen, it will relight. It you put the glowing splint into a test tube with carbon dioxide, it will stop glowing. A better test for carbon dioxide is to bubble it through a solution of limewater.
How do you identify oxygen gas?
Oxygen gas can be identified by its physical properties, such as its colorless and odorless appearance. It can also be tested by its ability to support combustion, as oxygen is necessary for fire to burn. Chemical tests, such as reacting oxygen gas with a fuel to form water and carbon dioxide, can also be used for identification.
How do you test for carbonic acid?
Carbonic acid cannot be directly tested for. However, you can indirectly test for its presence by measuring the levels of dissolved carbon dioxide in a solution using methods such as pH testing or titration methods. Carbonic acid is formed when carbon dioxide dissolves in water.
What ingredient is required to ensure that both the plant and person breath?
Carbon Dioxide. Plants do not breath. These simply exchange gases through stomata or lenticells. However, all living being respire and as a result CO2 comes out during oxidation of respiratory substrates. Therefore outcome of CO2 from an individual is tested>
What is a good hypothesis for an earth science research project?
A good hypothesis for an earth science research project could be: "Increased levels of carbon dioxide in the atmosphere are contributing to rising global temperatures, leading to more frequent and severe weather events." This hypothesis can be tested by analyzing historical climate data and studying trends in atmospheric carbon dioxide levels.
What elements and compounds come out after making oxygen test?
After performing an oxygen test, the products that may result include carbon dioxide, water vapor, and other combustion byproducts depending on the substance being tested. If the substance contains impurities, it may also produce sulfur dioxide, nitrogen oxides, or other gases.
How can it be classified that the gas given is carbon dioxide when dilute hydrochloric and sodium carbonate reacts?
When dilute hydrochloric acid is added to sodium carbonate solution, it produces bubbles of carbon dioxide gas. This can be tested by passing the gas through limewater, which will turn milky if carbon dioxide is present. Additionally, the gas can be identified using a flame test, where carbon dioxide does not support combustion.
What gas do bubbles contain if there is an experiment wether pondweed still has as much photosynthesis underwater?
The bubbles produced by pondweed during photosynthesis underwater contain oxygen gas. This is a byproduct of the process and indicates that photosynthesis is occurring. If the experiment permits the bubbles to escape, they can be collected and tested to confirm the presence of oxygen.
What does an oxygen meter measure?
An oxygen meter measures the concentration of oxygen in a particular environment, usually expressed as a percentage of oxygen in the air. It is commonly used in medical settings to monitor oxygen levels in blood (pulse oximeter) or in industrial settings to ensure safe oxygen levels for workers.
How can you test carbon dioxide?
One common way to test for carbon dioxide is to bubble the gas through limewater (calcium hydroxide solution). When carbon dioxide reacts with limewater, it forms a white precipitate of calcium carbonate. Additionally, carbon dioxide can be tested using pH indicators like bromothymol blue, which changes color in the presence of carbonic acid formed when carbon dioxide dissolves in water.
