The function of light is to excite a specialized chlorophyll in the reaction centre either by Direct absorption or more frequently, via energy transfer from an antenna pigment, This excitation process can be envisioned as

a.) An electron from the lowest-energy filled orbital of the chlorophyll to the highest-energy unfilled orbital

b.) An electron in the upper orbital is only tightly bound to the chlorophyll and is difficult to fetch the electron nearby molecules

c.)  The electron in the upper orbital is only loosely bound to the chlorophyll and is easily lost if a molecule that can accept the electron is nearby

d.) The promotion of an electron from the highest-energy filled orbital of the chlorophyll to the lowest-energy unfilled orbital

Which combination is CORRECT?

In Prey population of genotype A1A1(100), A1A2( 200) and A2A2( 100) present in island, when predator introduced this area results ¼ of A1A1 and ½ of A1A2 killed over time however, no genotype A2A2 kill. What will be frequency of A1 allele in the population?

#Question id: 3311

#Section 3: Genetics, Cellular and Molecular Biology

Consider a diploid population at Hardy-Weinberg equilibrium. For a locus with two alleles, the frequency of the A1A1 genotype is 0.01) The frequency of A2A2 is

#Question id: 3312

#Section 3: Genetics, Cellular and Molecular Biology

Hardy-Weinberg equilibrium, the frequencies of the two alleles A1 and A2 is 0.4 and 0.6. When you consider A2 is dominant allele of genetic disorder. The frequency of defected individuals, in population size 1000 is
