Question

you are a crime scene investigator and have collected material from the shoes of a body that was dumped by a local pond. you are trying to determine if the unknown material you collected contains bacterial cells. what should you look for as you examine the specimen under the microscope? a nucleoid region with a single chromosome. chloroplasts and mitochondria. a well - defined nucleus and distinct chromosomes. ribosomes. a cell wall

Explanation:

Prokaryotic cells lack a well - defined nucleus and membrane - bound organelles like chloroplasts and mitochondria. They have a nucleoid region with a single chromosome. A cell wall and ribosomes are present in both prokaryotes and eukaryotes. So, for a suspected bacterial (prokaryotic) cell, we should look for a nucleoid region with a single chromosome.

Answer:

A nucleoid region with a single chromosome.
