Answer:
a. parasitism:
The parasite benefits by harming the host e.g hookworms and humans
b. commensalism
In this association, one species benefits while the other is unaffected (its not harm and dies not benefit) e.g. epiphytic orchids and trees
c. mutualism
Here, both species benefit as seen in rumen bacteria and cows
Explanation:
Parasitism = +/- relationship
The predator benefits by harming the host. E.g. hookworms and humans. The hookworm (parasite) eat man blood while man (host) loses blood to it.
Commensalism = +/0 relationship
One specie(s) benefits while the other specie(s) neither benefits nor is harmed. E.g. epiphytic orchids live on tree branches or tree trunks as it's habitat or shelter while the trees neither benefits nor is harmed
Mutualism = +/+ relationship
Both organisms benefit in this relationship. E.g. rumen microbes aids grass digestion in cows, while the microbes benefit as it obtain steady food or nutrient from the cow

You would predict that indoleacetic acid, a plant hormone, would have is a Auxin.
A chemical known as indoleacetic acid (IAA) is produced by plants and a few microorganisms (3, 4). IAA is important for both root and shoot growth in plants. By means of an efflux pump (PIN1-7) and a specified importer (AUX1), the hormone travels from one area of the plant to another (5, 6).
Auxin mainly help in complex mechanism of a plant , which lead many metabolic activities in plant .
What is Auxin ?
- Auxin plays a crucial role in controlling plant growth and development by regulating embryonic development, root and stem tropisms, apical dominance, and the transition to blooming.
- It is used to start off shoot growth in culture and encourages lateral and accidental shoot growth.
- Aids in overcoming auxin-induced apical dominance.
- Encourage the development of leaves' chloroplasts.
- Encourages the mobilization of nutrients and delays leaf senescence.

Answer:
convergent evolution:
Explanation:
organisms which are not closely related may adapt similarly when exposed to similar environments, thus have similar structures.
