Explanation:
B. Catalysts are not changed during a chemical reaction.
The reasoning behind this is because these unidentified plants could be used to cure diseases, used for food, and many scientists may even use these plants to create cosmetics. I really hope this helps and I just thought this off the top of my head so its may not be 100% accurate but its the basics of it.
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
C because you have to have genetic material .
