You have a series of cells, all of which were derived from tumors, and you first need to find out

which ones are malignant. what could you do?

a. see which ones are not overproliferating.

b. find out which ones have a higher rate of apoptosis.

c. karyotype samples to look for unusual size and number of chromosomes.

d. measure metastasis.

e. time their cell cycles.

The correct answer is option c. "Karyotype samples to look for unusual size and number of chromosomes".

Explanation:

The number and arrangement of chromosomes are two features that differentiate between a cancer cell that is malignant and a cancer cell that is non malignant. Fortunately, a basic karyotype experiment will be enough to spot a malignant cancer cell. In a karyotype, an unusual large size and an unusual number of chromosomes (aneuploidy) will be indicatives of the presence of malignant cancer cells.

there are mainly three domains in biological classification namely; archaea, bacteria, and eukarya.

archaea includes all the prokaryotic cells which are characterized by their lipid membranes. they have branched hydrocarbon which is attached to glycerol through an ether linkage.

bacteria includes all the prokaryotic cells, the cell membrane of which are made up of the unbranched fatty acid chain. in addition, they are attached to glycerol through an ester bond.

eukarya includes all the eukaryotic cells, that is, the cells contain a nucleus and other membrane-bound cell organelles.

they can be autotrophic as well as heterotrophic, unicellular as well as multicellular

they include kingdoms like protista, plantae, animalia, fungi et cetera.
