TRUE OR FALSE QUESTIONS 1. Ribosomes float in the cytosol(cytoplasm) of the prokaryotic cell. This is no endoplasmic
reticulum to attach to.
2. A large mass of DNA is found in the nucleoid region in the cell. There is no nucleus to
contain the DNA. Prokaryotic DNA is actually circular in shape.
3. There are also smaller pieces of circular DNA called plasmids. Plasmids can be shared
with other prokaryotic cells.
4. Pili are small extensions of the cell membrane and can be used to touch other
prokaryotes.
5. The outer most layer of many prokaryotic cells is called the capsule.
6. The middle layer between the cell membrane and the capsule is the cell wall.
7. The cell membrane contains all of the cytoplasm/cytosol, ribosomes, and DNA within the
cell.
8. Many, but not all, prokaryotic cells have flagella that help them move.

*will mark brainliest for first correct answer* which of the following is most likely to affect the biodiversity of a park ecosystem? a. less rain than usual for several months b. ongoing pollution from a nearby factory c. park rangers plant a new type of tree d. disease wipes out an entire population

Over the past 60 years, many amphibian species have experienced significant population declines and some species have become extinct. scientists suspected that local human activities such as the destruction of wetlands, regional pollution, and deforestation were the main reasons for these losses. however, research over the past 20 years reveals significant amphibian population declines in protected areas of the world, such as nature preserves and parks. these global declines suggest widespread problems including increased ultraviolet radiation, acid rain, and disease. in switzerland, for example, 14 of the 20 native amphibian species are threatened with extinction. chytridiomycosis is a fungal disease first identified in 1998 as a cause of massive amphibian deaths. in some severely impacted populations, a few individuals have survived, perhaps because of some natural resistance. if these resistant individuals continue to survive and prosper, new resistant populations might emerge. this would be an example of the founder effect artificial selection genetic drift natural selection sexual selection
