or coelomates: fluid-filled body cavity completely lined with cells from the mesoderm that separates digestive tract from the outer body wall, two openings for digestive system
Answer:
Option C
Explanation:
As per the paleontologists, the anchored tubular structures of fossilized Funisia dorothea showed dense clusters which are believed to be formed by mating of floating egg and sperms in the water. Also traces have been found that states asexual mode of reproduction through budding where buds were formed in the same way as that of coral, sponges etc and then these buds grew into full sized Funisia dorothea. Thus, the fossil species have the complex ability to produce both sexually and asexually.
Option C
Answer:
A
Explanation:
Natural selection occurs when an environment makes organisms with certain traits more likely to survive and reproduce.
Asexual reproduction results in no genetic variation (meaning differences in traits, also called divserity). Genetic variation must be present for certain organisms to be better suited to their environment, because in its absence all organisms share the same traits. This rules out B, C, and D. I hope this helps :)
The correction option is B. The plants that belong to phyllum anthophyta are heterosporous, that is, they produce both male and female reproductive organs separately. Fruits grow when the male gamete fertilizes the female ovary. Their fruits are always fleshy with seeds inside them. A good example of a plant that belong to this phylum is pawpaw.
