Answer:
I can think of these three.
Explanation:
1. To determine the concentration of an acid or base.
If you exactly neutralize an acid or base by titrating it with a standard solution, you can calculate its concentration
2. To determine the pKₐ or pKb of an acid or base
If you draw a titration curve, the pK of the sample is the pH when you have added half the volume of titrant needed to reach the end point.
3. To follow the rate of a reaction
If a reaction produces an acid or base, you can titrate the product as it is formed. The volume of titrant will be a measure of the rate of the reaction.
Answer:
In this question, consider how to correct two options:
The most successful is that a steroid hormone derived from components that contain cholesterol, this is because they are made up of lipids.
And the second correct option is that to be transported in blood fluids, THEY ARE GENERALLY (NOT ALWAYS) transported by transport proteins to their target organ, which may be close, far or even the same as the productions.
Explanation:
A variety of steroids and synthetic steroids have also been devised. Most are steroids, but some nonsteroidal molecules can interact with steroid receptors due to the similarity of their forms. Some synthetic steroids are weaker, and some much stronger, than natural steroids whose receptors they activate.
Answer: The new pressure is 7.1 atm
Explanation:
To calculate the final pressure of the system, we use the equation given by Gay-Lussac Law. This law states that pressure of the gas is directly proportional to the temperature of the gas at constant pressure.
Mathematically,
where,
are the initial pressure and temperature of the gas.
are the final pressure and temperature of the gas.
We are given:
Putting values in above equation, we get:
Hence, the new pressure is 7.1 atm
Algae is not an abiotic factor.
