Question

3/19
which organisms are most closely related?
equus caballas (horse) & equus burchellii (zebra)
naja naja (cobra) & glycine max (soya bean)
ophiocomina nigra (black brittle star) & brassica nigra (black mustard)
cyanea artica (jellyfish) & ctenodiscus crispatus (mud starfish)

Explanation:

To determine closely related organisms, we check their taxonomic classification. Organisms with the same genus (first part of scientific name) are more closely related. Equus caballus (Horse) and Equus burchellii (Zebra) share the genus Equus, indicating a closer evolutionary relationship than the other pairs (which have different genera or even kingdoms, like animal - plant in the cobra - soya bean pair).

Answer:

A. Equus caballus (Horse) & Equus burchellii (Zebra)
