Description 2 describes a commensal symbiosis. The answer is D, commensalism.
The Diplomonads and Parabasalids are the two groups that are adapted to anaerobic conditions and contain modified mitochondria that lack DNA.
<u>Explanation:</u>
The existence of a mitochrondrial-remnant organelle and nonfunctional, named a mitosome distinguishes diplomonads. Parabasalids are distinguished by a semi-functional mitochondria termed as hydrogenosome; they are made up of parasitic protists, including Trichomonas vaginalis.
Diplomonads function in anaerobic circumstances, and use alternate pathways to generate energy, like glycolysis. Growing cell of the diplomonad has two identical nuclei and utilizes multiple locomotive flagella. Trichomonas vaginalis, a parabasalid that induces a human sexually transmitted infection, uses these pathways to pass via the urogenital tracts of males and females.
1. The data shows that during mating season, the female is most likely to spend time with the normal tailed swordtail. She she spends less time around male swordtails with all black tails, and the least time around male swordtails with all yellow tails.
2. During mating season, since females want to spend the least time with a male swordtail with an all yellow tail, it’s reasonable to predict that these males will have less chance to mate. Female fish lay their eggs in a nest when they are near a male they want to mate with for fertilization. Unless the all yellow tail is a recessive trait, over time, I would expect that the all-yellow tail swordtails would die off.
