Answer:
Role of photosynthesis
It's not oxygen production. The primary function of photosynthesis is to convert solar energy into chemical energy and then store that chemical energy for future use. For the most part, the planet's living systems are powered by this process.
Explanation:
The amount of acetic acid in vinegar is determined by the volumetric titration of acetic acid with standardized NaOH solution. When atmospheric carbon dioxide is absorbed by deionized water used in the titration, it would react with water and form carbonic acid.
When the deionized water is contaminated with carbonic acid, it would result in the consumption of a higher amount of NaOH for neutralization. Therefore, the amount of acetic acid determined would be too <u>high</u> than it should be.
I think it’s A it’s showing the par-ten to those certain things how it works
The right is Separation by density
.
Take the blood which is a good example of a heterogeneous mixture.
Blood is a vital liquid in our body, which transports oxygen from the air to our lungs so we can breathe. It is also used to eject wastes, such as carbon dioxide, to bring cells and molecules of the immune system to the tissues, and to spread hormones throughout the body. It corresponds to plasma, red blood cells, white blood cells, platelets and hemoglobins combined.
In medical tests centrifugal force is used to separate the different components of the blood.
In general, the centrifugation will allow to separate and analyze the different components of the blood, to know if the rate of white blood cells in the blood of a patient, for example, is normal, and therefore to know if his system Immune is integrity.
Under the action of centrifugal force, the solid components in the blood are drawn to the bottom of the tube in which the blood is contained. The centrifugal force then acts as an accelerated settling. It separates plasma from red blood cells and white blood cells.
