Prairie dogs once covered the expanses of the Great Plains. Their grazing made the grass more nutritious for the huge herds of bison, and a variety of snakes, raptors, and mammals   preyed on the rodents. In fact, the black- footed ferret (now endangered) specialized in prairie dog predation. Today, growing housing and agricultural developments have covered many prairie dog towns. Which of the following statements about prairie dogs is true?

The rate of photosynthesis when red and far-red light are given together is greater than the sum of the rates when they are given apart, the effect provided essential

evidence in favor of the concept that photosynthesis is carried out by two photochemical systems working in tandem but with slightly different wavelength optima

this effect is known as

Organization of the protein complexes the photosystems I and II Are spatially separated in the thylakoid membrane, choose the correct arrangement of PSI and PSII on the membrane ;

a.) The PSI reaction centre and its associated antenna pigments and electron transfer proteins, as well as the coupling-factor enzyme that catalyzes the formation of ATP, are found almost exclusively in the stroma lamellae and at the edges of the grana lamellae

b.) The PSI reaction centre, along with its antenna chlorophylls and associated electron transport proteins, is located predominantly in the stromal lamellae

c.) The PSII reaction centre and its associated antenna pigments and electron transfer proteins, as well as the coupling-factor enzyme that catalyzes the formation of ATP, are found almost exclusively in the stroma lamellae and at the edges of the grana lamellae

d.) The PSII reaction centre, along with its antenna chlorophylls and associated electron transport proteins, is located predominantly in the grana lamellae
