Answer:

The pipe cleaners should be made circular to signify that prokaryotes do not have chromosomes

Explanation:

Prokaryotic and eukaryotic cells have a number of distinct features. Prokaryotes lack membrane-bound organelles, whereas eukaryotic cells are compartmentalised with different organelles performing different function.

As a result, prokaryotes no not possess a nucleus, where the DNA is housed in the cell. Eukaryoric DNA is organised into chromosomes. However, prokaryotic DNA is much more simple (and there is usually much less of it), and instead of forming chromosomes, it is organised into a singular, circular molecule, sometimes called the bacterial chromosome.

Therefore, the student will need to take one pipe cleaner and form a circle with it to make the bacterial DNA.

Conventionally pasteurized milk is sterile.<br> a. True<br> b. False
spin [16.1K]

Answer: False

Explanation:

Conventionally pasteurized milk is not sterile it gets sterile after it is homogenized. The process of pasteurization involves sudden heating and sudden cowling of milk which does not kills all the microorganism but is intended to kill some of the bacteria and inactivates some enzyme.

Homogenization is a completely separate process  which involve mechanical breakdown of fat molecules in the milk which increases the shelf life of milk by preventing the cream from rising at the top.

Hence, the given statement is False.
