Answer 4

Horizontal gene transfer
Transformation: incorporation of foreign DNA taken up from the environment
Transaction: incorporation of DNA delivered by a virus
Conjugation: transfer of DNA between prokaryotic cells that are connected

Question 5

Now do the metabolic strategies of prokaryotes differ from those of eukaryotes in both number of options and specifics

Prok-‘4 options: chemoautotroph, chemoheterotroph, photoUtotroph, photoheterotroph
Euk-2 options: photoUtotroph, chemoheterotroph

Question 6

What is the difference between oxygenic photosynthesis and anoxygenic photosynthesis

Answer 6

Oxygenic uses CO2 and produces O2

Anoxygenic dosent use oxygen. Instead uses h2S or Fe 2+ and produces oxidized versions of these instead of O2

Question 7

Why is the difference between anaerobic respiration and aerobic respiration
Which kinda do euk exhibit?

Answer 7

Aerobic uses oxygen
Anaerobic uses sugars or Fe3+
Only aerobic. Anerobic respiration is different from Anerobic metabolism
