Question

1. Why oh Why did we use substandard shielding on our Martian greenhouse? Please explain the effects of the following mutations and justify your answer for each (50 pts total, 5 pts each) a. The water splitting complex of PSIl works at about half the rate it did previously b. The number of antenna molecules in the photosystems (chlorophyll, carotenoids) has been decreased by 80% but the special pair is intact. c. Cytb6/f complex can no longer oxidize the quinones from PSII. d. A gene for flavanoid production associated with nodulation has had a premature stop codon inserted into it e. Expansins in guard cells (which control stomata opening and closing) are no longer active f. Secondary cell wall formation is inhibited g. A cell surface amylase has been converted to a cellulase h. The vacuole has been eliminated i. Auxin efflux proteins are equally distributed across the cell surface (not polar anymore) j. Cyclic electron flow between PSI and the cytb6/f complex has been blocked

greenhouse on Mars .. no dayes provied

Answer 1

Greenhouse effect in Mars

Mars mainly have carbon-dioxide gas in the atmosphere which is a green house gas that protect planet from having very low temperature where life cannot sustain.

a. If the water splitting complex will decrease its rate to 50 percent, then less electron will released and hence , less carbon dioxide will be produced and there will be more greenhouse effect.

b. As, the special pair is intact, there will be no effect on the carbon dioxide production and there will be no change in the greenhouse effect.

c. if this mutation take place, then less electron will released and hence , less carbon dioxide will be produced and there will be more greenhouse effect.

d. As, this mutation is not related with carbon dioxide production and there will be no change in the greenhouse effect.

e. As, the guard cell regulate stomata opening, through which carbon dioxide enter and exit, less carbon dioxide will be produced and there will be more greenhouse effect.

f. As, this mutation is not related with carbon dioxide production and there will be no change in the greenhouse effect.

g. As, this mutation is not related with carbon dioxide production and there will be no change in the greenhouse effect.

h. According to this mutation, less carbon dioxide will be produced and there will be more greenhouse effect.

i.According to this mutation, then less electron will released and hence , less carbon dioxide will be produced and there will be more greenhouse effect.

j. According to this mutation, then less electron will released and hence , less carbon dioxide will be produced and there will be more greenhouse effect.
