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
Important keywords to include are obviously Individualism and Collectivism, as well as distinct/seperate, interact, and purpose.
Answer:
Rice, Corn and Bamboo
Explanation:
Parallel venation is a kind of venation in which the veins runs parallel to the to the length of the leaves from its base of the leaf to the apex of the leaf or the tip of the leaf.
It is a characteristics of many monocot plants.
Few example of plants having parallel venation are grasses, bamboo, rice, corns, banana, musa, canna, etc.
Answer:
Dinoflagellates
Explanation:
Protists are unicellular eukaryotes and dinoflagellates is a protist that is responsible for causing annual Florida red tides. When a large amount of dinoflagellates accumulates in the ocean they make the sea color red which is also called an algal bloom.
They also secrete a toxin that kills lots of aquatic animals. They are also toxic to other creatures like birds, humans. They come together to reproduce in a definite area therefore they accumulate together in large amounts causing red tides annually. Therefore the correct answer is dinoflagellates.
