Why respiration caused a drop of red ink to move towards a test tube?
Let's say that there is a substance in the test tube that absorbs carbon dioxide okay? So when we respire, we give out carbon dioxide, which is considered quite warm in temperature. The carbon dioxide will be absorbed by the substance so only oxygen will remain inside the test tube. Since oxygen is produced by plants and is from our suroundings, you could say that oxygen is quite cool in temperature. So, the drop of ink will move towards the test tube because the drop of red ink is a type of metal and it will contract when it is cool or cold. So that is why respiration causes a drop of red ink to move towards the test tube. I hope that answers your question guys!
Is a drop of hydrochloric acid on marble produces carbon dioxide gas a chemical change?
Yes.
When mixed with a drop of bromthymol blue what will cause the indicator to turn from blue to yellow?
Bromthymol Blue indicates Carbon dioxide is present. It is also a general acid-base indicator. When it turns green it is at the endpoint of the titration. When it turns yellow, it is overshot and thus acidic.
What happens if you drop a sugar cube in warm water and stir?
The sugar will dissolve in the warm water.
What is the process of photosynthesis from start to finish?
1. First the chlorophyll (the chemical that makes plants leaves green and traps sunlight) traps the sunlight in the leaves. (The sunlight provides energy for the plants.)2. Next the sunlight gives the plant energy to start the food-making process.3. Then the roots suck nutrients up to the leaves and then the leaves mix carbon dioxide, the nutrients and water to make their food. (sugar)4. Finally they throw out their waste (oxygen).
Where does blood get rid of carbon dioxide?
No. The red blood cells get oxygen at the lungs, not drop off carbon dioxide.
What does the blood drop off in the lungs?
it drops off co2 (carbon dioxide)
What happens to the blood concentration level of carbon dioxide following increased breathing?
With increased breathing, levels of carbon dioxide in the blood drop and levels of oxygen rise.
A drop of blood is releasing oxygen and picking up carbon dioxide what type of blood vessel does this occur in?
capillaries
Why does blood get pumped into the lungs?
It needs to get oxygen from the lungs, or drop off carbon dioxide to exhaled out of the body.
What do red blood cells drop off at the lungs?
Actually, they don't drop off anything at the lungs. They do pick up oxygen. Carbon dioxide is dropped off but it is carried dissolved in the blood itself.
Name 2 things that the blood drop off that the cells use to live?
Blood delivers nutrients and oxygen to cells and takes away carbon dioxide and wastes.
Where red blood cells drop off carbon dioxide and pick up oxygen?
Yes, some CO2 is returned to the lungs by hemoglobin transport.
What happens when blood goes into the lungs?
Oxygen is inhaled into the body through the nose or the mouth. It travels through the trachea, to the bronchi, then through the bronchial tubes, and finally settles in the alveoli, which are tiny sacs in the lungs. As the blood is pumped into the lungs through the pulmonary artery of the right ventricle of the heart, the oxygen-depleted blood goes to the capillaries which wraps the alveoli. In the capillaries, oxygen is given from the alveoli to the blood, and blood would drop of carbone dioxide into the alveoli. Once this process is complete, the blood would return to the heart, and the carbone dioxide would be expelled from the body as we exhale.
How does oxygen affect blood pH?
If lactic acid is excreted by the cells, then the blood would become more acidic, and the pH would drop. If more Carbon Dioxide (CO2) is dissolved in the blood, then more carbon dioxide will mix with water to form: CO2 + H2O --> H2CO3, Carbonic Acid, and the pH will also drop.
How is blood in the pulmonary artery different from blood in arterys?
The pulmonary artery runs from the heart to the lungs. It is the only artery that doesn't carry oxygenated blood. That makes it a darker red than the blood in other arteries, so it looks blue under your skin.
How does oxygen travel throughout the body?
First you breath it in and then it goes through you blood stream dropping off oxygen molecules and picking up carbon dioxide all through the body and then it goes to the lungs to get more oxygen and drop off the carbon dioxide so it can be exhaled.
