26. Based on the life cycle of ferns shown in Figure 3, which of the following statements are true? (select all that apply.) (A) The life cycle of this fern is haplodiplontic. (B) The alternation of generations in this fern is isomorphic. (C) This fern is isogamous. (D) Cell ① is the primary dispersal unit in this fern. (E) The young sporophyte is dispersed within maternal protective tissue (a seed).

25. Figure 3 illustrates the life cycle of a fern, in which four unicellular stages are labeled ①-④. Assuming the haploid chromosome number (n) = 34, which of the following statements are true? (select all that apply.) (A) Cell ① is derived from a spore mother cell through meiosis. Each spore mother cell produces 64 spores in leptosporangiate ferns. (B) Cell ② is produced by mitosis in a female or hermaphroditic gametophyte. (C) Cell ② has 17 chromosomes in its nucleus. (D) Cell ③ is the male gamete of the fern. (E) Cell ④ is expected to be homozygous across the genome.

24. Considering both Figure 1 and Figure 2 which of the following conclusions are best supported? (Select all that apply) (A) Dietary strategy has no effect on mammalian diversification. (B) Repeated transitions among dietary strategies have contributed to mammalian diversification. (C) Omnivory is an irreversible evolutionary state in mammals. (D) The inferred probability of direct transitions between herbivory and carnivory is low, with most transitions occurring via an intermediate omnivorous stage. (E) Ecological specialization, in this case, can promote rather than limit long-term diversification.
