Q
  1. According to the video Bacteria, regarding the bacteria that colonize your skin, it is good or bad? (and know why or why not)
A

Some of the bacteria that colonize your skin are beneficial and actually keep harmful strains and other types of pathogens from growing

Q
  1. What is the purpose of the cell wall of prokaryotes?
A

Protection doesnt let cell rupture (cellulose material) maintain shape, can’t lyze.

Q
  1. Which statement describes the function or composition of bacterial endospores?
A

Endospore- thick walled spore around the genome and a small portion of cytoplasm when they are exposed to nutrient poor conditions.

17
Q
  1. Which statement does not describe the cellular interior of a basic bacterial cell?
A

Internal membrane
Nucleoid region
Ribosomes

18
Q
  1. Prokaryotes reproduce rapidly, allowing genetic variations to spread quickly through a population. How does this spreading of genetic information occur?
A

Binary fission- replicating doubling genetic information, making split, similar to mitosis, uses fitz protein

19
Q
  1. Certain factors can increase the likelihood of mutations occurring in bacterial cells. Which statement does not describe one of those factors?
A
20
Q
  1. What can be the result of a genetic (DNA or plasmid) mutation in a prokaryote?
A

spreading that plasmid information

21
Q
  1. Which statement describes a photoautotrophic bacteria?
A
22
Q
  1. Which statement describes a chemoautotrophic bacteria?
A

obtains energy by the oxidation of electron donating molecules int their environments

23
Q
  1. Which statement describes photoheterotrophic bacteria?
A

purple, nonsulfyur bacteria use light as their sourced of energy but have to get carbon from organic molecules.

24
Q
  1. Which statement describes chemoheterotrophic bacteria?
A
25
Q
  1. Which statement describes bacteria as a plant pathogen?
A
