Determine whether each of the following is a characteristic of the life cycle of a seed plant, a seedless plant, or both. Double
Gnoma [55]

Double fertilization-plants with seeds (flowering plants), two male gametes joining with female gametophyte

Gametophyte generation-both (haploid, sexual stage stage-gametophyte, and the diploid stage that produces spores – sporophyte)

Endosperm formed-plants with seed because it is a tissue formed inside the seed which surrounds the embryo and provides nutrition

Mitosis-both (mitosis occurres in spores)

Spores develop into gametophytes-both but, in seedless plants sporophyte produces spores that will develop into a new organism (multicellular gametophyte) using mitosis, while spores of seed plants are produced internally and develop into more complex structures.

Regarding the "East Side Story" hypothesis, what would paleoanthropologists need to show that it was false?
ANEK [815]

Answer:

Evidence of fossil apes and hominids in both East and West of the great rift valley

Explanation:

<em>The East Side Story hypothesis opined that a tectonic plate movement created a seismic split in the earth, thus deepened the rift valley and created a geographical barrier between the east and the west of the great rift valley. The barrier created a kind of geographical isolation between the ancestors of hominids, dividing them into two with each population taking different evolutionary paths. </em>

<em>Thereafter, the ancestors in the western side of the rift valley evolved into the chimpanzee's family while those in the eastern side ultimately evolved into humans. </em>

<u>Thus, providing the fossils of apes and that of hominids in both East and West sides of the great rift valley will render the hypothesis invalid.</u>
