Option A,B,C,E

Chromosomes are rod shaped structures that contain DNA, are located in the nucleus, occur in numbers that are the same for all members of a certain species, are organized into karyotypes for scientists to analyze

A chromosome is the threadlike arrangement of DNA and protein-containing genetic erudition. Chromosomes are packaged and saved inside the nucleus. Various species have distinct amounts of chromosomes. An organism's complete assortment of chromosomes can be observed by practicing pictures of cells dividing. These pictures are then designed to produce a karyotype.

All the various chromosomes of an organism get up that organism's genome.DNA is the construction block of the genetic material observed in all living things. A very long chain of DNA can create a chromosome. In these chromosomes are areas designated as genes that code for particular proteins.

genetic variation will increase because of a new habitat and food source.

explanation:

b tumor cells have a cell wall instead of a membrane

explanation:

tumor cells different from normal cells because tumor cells have a cell wall instead of a membrane.
