C. Directions: Answers must be in essay form. Outline form is not acceptable. Labelled diagrams may be used to supplement discussion, but in no case will a diagram alone suffice. It is important that you read each question completely before you begin. question:
The unit of genetic organization in all living organisms is the chromosome.
How does the function and structure of the chromosome differ in prokaryotes?

The structure and function of the chromosome are different in both the prokaryotic chromosome and eukaryotic chromosome. They differ in their size as the genetic information they carry is different from one another.

Eukaryotic chromosome have a different shape from the prokaryotic chromosome as the bacterial chromosome is circular and less complex due to no histone found in prokaryotes as we see in the eukaryotic chromosome. SIze of the bacterial or prokaryotic chromosome is also small and not found in condensed form as these cells carry less genetic information than eukaryotic cells.

the abdomen (less formally called the belly, stomach, tummy or midriff) constitutes the part of the body between the thorax (chest) and pelvis, in humans and in other vertebrates. the region occupied by the abdomen is termed the abdominal cavity. the stomach secretes acid and enzymes that digest food. ridges of muscle tissue called rugae line the stomach. the stomach muscles contract periodically, churning food to enhance digestion. the pyloric sphincter is a muscular valve that opens to allow food to pass from the stomach to the small intestine.

explanation:

the fossil record extends back to a dog-like ancestor some 55 million years ago, which gave rise to the first horse-like species 55 to 42 million years ago in the genus eohippus.
