Hi there!

It is necessary to rinse the inside of an Erlenmeyer flask with deionized water periodically to wash the flask without adding ions which could affect the titration. 

If you wash an Erlenmeyer flask with regular tap water, you are adding ions, like sodium or chlorine, which could make you miss the equivalence point by only tenths of mL (that's a big difference when titrating). This is why when washing you use deionized water to clean the flask while ensuring that your titration is accurate.

Have a good day!

What is an example of codomiance
satela [25.4K]

Codominance means that neither allele can mask the expression of the other allele. An example in humans would be the ABO blood group, where alleles A and alleles B are both expressed. So if an individual inherits allele A from their mother and allele B from their father, they have blood type AB.

Answer:

16. mitochondria

17. lysosomes

18. smooth Endoplasmic Reticulum

19. golgi body

20. golgi complex

Explanation:

16. Mitochondria are double membrane-bound cell organelles responsible for the supply and storage of energy for the cell

17.  While cells mainly use lysosomes to dispose of trash. Sometimes they simply hang onto their trash, performing the cellular equivalent of sweeping it under the rug

18. Are the storage organelle, associated with the production of lipids, steroids, and also responsible for detoxifying the cell.

19.  The Golgi body is the sorting organelle of the cell. Proteins are transported from the rough endoplasmic reticulum (RER) to the Golgi.

20. is responsible for sorting and correctly shipping the proteins produce the ER. Just like our postal packages, which should have a correct shipping address, the proteins produced in the ER should be correctly sent to their respective address. It is a very important step in protein synthesis.
