Answer:
a)species x is anaerobic, and species y is aerobic
Answer:
P. aeruginosa
Explanation:
<em>P. aeruginosa</em> is a gram-negative bacteria that belongs to the family Pseudomonadaceae.
From the given question the following points lead us to conclude that the colony that will be growing would be of P. aeruginosa :
1. Flat spreading colonies with a metallic sheen on SBA - <em>P. aeruginosa</em> is known to produce smooth colonies with flat edges.
2. Fluorescent green color in the media with clear colonies on cetrimide agar - <em>P. aeruginosa</em> is known to produce pyoverdin which is a fluorescent pigment under low iron conditions.
3. Medium clear colonies that have a "fruity or grape-like odor" on MacConkey Agar - <em>P. aeruginosa</em> has a sweet fruity odor which is its characteristic odor because of the production of trimethylamine.
Thus, from all these characteristics one can conclude that the organism in the culture is <em>P. aeruginosa. </em>
The answer is <span>b. Predation and mutualism.
</span>
<span>Mutualism is a relationship between two different species in which both species benefit. In clownfish - sea anemone relationship, the clownfish is protected from predators (butterfly fish) by the sea anemone, so the clownfish benefits from this relationship. The sea anemone gets more prey thanks to a coloration of the clownfish, so the sea anemone also benefits from this relationship. Since both species benefit, their relationship is an example of mutualism.</span>
<span>On the other hand, a relationship between the sea anemone and butterfly fish is an example of predation. Predation is the relationship in which predator hunts and feeds on its prey. In the example, the butterfly fish feeds on the sea anemone, so it must be predation.</span>
