PLZ ASAP A scientist is using a microscope to observe a type of
bacteria.

Which two structures would the scientist most likely see?PLEASE EXPLAIN WHY

A:nucleus and DNA
B:DNA and cell wall
C:cell wall and vacuole
D:vacuole and nucleus

The two structures most likely to be observed by the scientist when looking at a type of bacteria under the microscope are cell wall and vacuole (option C).

Explanation:

Bacteria are prokaryotic organisms that lack a nucleus, most of the organelles, and whose DNA is dispersed in the cytoplasm. Some types of bacteria have a plasma membrane surrounded by a cell wall, and may be equipped with vacuoles to perform their functions.

It is very likely that two structures that are most likely to be differentiated when a type of bacteria is observed under the microscope are the cell wall and the vacuole, according with information above.

The other options are not correct because:

    A and D. Bacteria lack a nucleus.

    A and B. Bacterial DNA is dispersed in the cytoplasm and is very difficult to observe under the microscope.

the answer to your question is b

when atoms of different types of elements join together, they make molecules called compounds. water consists of compound molecules made up of 2 hydrogen atoms and 1 oxygen atom. this is why it's called h2o. water will always have 2 times the number of hydrogen atoms as oxygen atoms.
