Question

what process accounts for species diversity? a mitosis b meiosis c predation d symbiosis

Explanation:

To determine the process accounting for species diversity, we analyze each option:

• Option A: Mitosis is cell division for growth/repair, producing identical cells, not related to species diversity.
• Option B: Meiosis involves genetic recombination (crossing - over, independent assortment) during gamete formation. This genetic variation is a key factor in evolution and species diversity as it provides the raw material for natural selection.
• Option C: Predation is an interaction between species (one preying on another) and affects population dynamics but not the origin of species diversity.
• Option D: Symbiosis is a close relationship between different species (e.g., mutualism, commensalism, parasitism) and influences species interactions but not the fundamental process creating genetic variation for species diversity.

Answer:

B. meiosis
