Answer:
D
Explanation:
there are around as many bacteria cells as there are human cells in the human body.
The human genome density ranges between 12-15 genes per Megabase pairs. This is because humans have approximately 2000 genes in a total of approximately 3 billion base pairs. However, some primitive organisms have an even larger gene density
than humans. An example is bacteria with gene densities ranging between 100 –
500 genes/Mb. Gene density is therefore
not a good characteristic in determining
the complexity of an organism.

The phylum Arthropoda contains a wide diversity of animals with hard exoskeletons and jointed appendages. Many familiar species belong to the phylum Arthropoda—insects, spiders, scorpions, centipedes, and millipedes on land; crabs, crayfish, shrimp, lobsters, and barnacles in water (Fig. 3.72).
