The answer is <span>The flagellated sperm would not be able to swim to the eggs for fertilization.
</span><span>Their life cycle of mosses has alternation of generation -
a haploid gametophyte and a diploid sporophyte. Gametophyte produces haploid
gametes which fuse to form a diploid zygote. The zygote grows into diploid
sporophyte which produces haploid spores. The spores grow into gametophyte and
the cycle begins again.
</span>Mosses require water for reproduction. Before fertilization, the sperm swims to an egg through the water. Therefore, mosses require water for successful fertilization. In drought periods, without water, the sperm cell could not swim to the egg cell.
Answer:
The maintainance of the lytic and the lysogenic cycle is done by the Cro and the lambda repressor proteins when the number of bacteria is higher than the number of viruses that is the mode of infectivity or MOI the virus under goes the lytic cycle. This is done by the cleaving of the proteins.
So high nutrient concentration in the gut promotes the growth of the E coli that forms a protease that cleaves the Cro protein and causes the activation of the lysis in the bacteria. So in the high nutrient concentration the bacteria is itself responsible for its lysis.
