prefers PH 6.5-7.5

Answer 13

Neutrophiles-most bacteria

Question 14

prefers PH below 2

Answer 14

acidophiles

Question 15

low solute -water in = Lysis

Answer 15

hypotonic

Question 16

high solute-water out=shriveling

Answer 16

Hypertonic, nothing is living or thriving.

likes Salty environments

Answer 17

obligate HALOphiles

Question 18

Needs O2

Answer 18

obligate aerobe

Question 19

No O2

Answer 19

Obligate anaerobes-only one that does NOT have enzymes to eliminate free radicals.

Low O2

Answer 20

Microaerophile

Question 21

Tolerates O2 but does not need it

Answer 21

Aerotolerant Anaerobe

Question 22

Prefers O2

Answer 22

Obligate aerobe

Question 23

Step 1 to eliminate free radicals

Answer 23

SOD -produces hydrogen peroxide /superoxide dismutase

Question 24

Step 2 to eliminate free radicals

Answer 24

Catalase/peroxidase–neutralizes.

Question 25

Ions

Answer 25

iron, zinc, and copper-enzyme inorganic cofactors to function as a holoenzyme

aerobic respiration

Answer 29

Oxygen

Question 30

5 prime to 3 prime

Answer 30

leading strand

Question 31

fragmented strand

Answer 31

lagging strand /Okazaki fragment

Question 32

where DNA unwinding and DNA synthesis happens

Answer 32

Replicating Fork

Question 33

chemical mutation-looks like normal bases but pairs incorrectly -induced not natural point mutations

Answer 33

Base Analog

Question 34

induces thymine dimers creates covalent bonds between adjacent T's -distorts backbone-improper replication-frameshift mutation

Answer 34

UV Light -non-ionizing radiation

Question 35

slips in-between adjoining nucleotides makes a bulge in the backbone

Answer 35

Intercalating Discs

Question 36

ionizing radiation -energize electrons in atoms some e-s escape and strike other atoms ions react with DNA point mutations

Answer 36

X-rays and Gamma rays
