Question

1-Select all the false statements concerning photoautotrophic prokaryotes.

E- Pigments are used to capture photon energy

2- A non-pathogenic bacterium is infected by a virus. The bacteria continues to live and can now damage tissue by means of a proteolytic toxin. Check all the true statements.

A prophage is formed during this process.

3- Which observation provides the best evidence that mitosis did not evolve all at once during eukaryote evolution?

Mitosis differs based on the presence of cell walls.

4-Select all the true statements brown algae.

Brown algae are terrestrial.

5-The name chytrid refers to the structure that

initiates mitosis.

PLEASE ANSWER it ASAP i got no time !!

A- They use light and CO2 to synthesize organic molecules. B- All of these organisms produce O2 as a byproduct. C- They all use chlorophyll to absorb light energy. D- They use pigments to absorb light energy but only cyanobacteria use chloroplasts.

E- Pigments are used to capture photon energy

2- A non-pathogenic bacterium is infected by a virus. The bacteria continues to live and can now damage tissue by means of a proteolytic toxin. Check all the true statements.

A- The bacteria acquired the genes to produce the toxin from a phage. B- The virus is following the lysogenic pathway. C- Viral multiplication releases the toxin into the host. D- The toxin was directly given to the bacterium. E-

A prophage is formed during this process.

3- Which observation provides the best evidence that mitosis did not evolve all at once during eukaryote evolution?

A-Prophase differs between animal cells and fungal cells. B- Certain eukaryotic cells do not go through interphase. C- Certain plants regularly form haploid cells during mitosis. D- Cytokinesis is not present in most protists. E-

Mitosis differs based on the presence of cell walls.
