Some statements regarding C2, C3, C4 and CAM plants

a.) For Sucrose synthesis after C2 C3 and C4 cycle having different procedure

b.) C4  cycle reduces occurrence of C2 which is thermodynamically very expensive and toxic by increasing the assimilation of CO2 at high temperature almost at 350 C

c.) C4 plant is generally found in near to equator  and they are more abundant than C3 plant

d.) In Dark when stomata are closed and CO2 not assimilated in the CAM plants

The Norway rat (Rattus Norvegicus), a widespread pest, was controlled for about a decade by the anticoagulant warfarin. This chemical substance, placed in food pellets, is absorbed by the intestinal tract and inhibits the clotting of blood. After a population decline for about 10 years, rat populations increased and stabilized. In one European population, as illustrated in the graph below, the percentage of rats resistant to warfarin has remained fairly stable over a number of years.

Resistance to warfarin is governed by a dominant autosomal gene, R. More than 15 percent of the resistant animals are heterozygous at this locus (Rr). The table below indicates the response to warfarin and relative reproductive fitness of individuals that are homozygous or heterozygous for the dominant gene (R). The RR individuals have a 20-fold increase in vitamin K requirement over individuals.

Fitness is a measure of the reproductive success of a particular genotype. The highest fitness is 1.00.
Which of the following is most likely correct concerning the gene for resistance to warfarin?

A. Only 1% of the human genome consists of exons.
B. The genes (exons plus introns) comprise 25% of the genome.
C. 60% of human genes are alternatively spliced.
D. Up to 80% of the alternative splices change protein sequence, so the human proteome has 50,000 to 60,000 members.
