1. Predation (where one organism kills and eats another organism; predator and prey)
2. Competition (where species compete for a particular resource, even without coming in contact with each other)
3. Paratism (where a parasite is on an animal; harms it and feeds on it without killing them instantly)
4. Mutualism (both species benefit from each other)
5. Commensalism (one organism benefits, but the other one is neither helped nor harmed)
The answer is
B, a euglena uses a flagella in order to move. Euglena is a one celled organism
under the Kingdom Protista. A flagella (or flagellum plural) is a long strand
like structure that is located in the front end part (more like a tail in front).
It flips to the left and right in order for the organism to move. It is
connected to the reservoir, which contains the storage of food for the
organism.
Answer:
During active transport, substances move against the concentration gradient, from an area of low concentration to an area of high concentration. This process is “active” because it requires the use of energy (usually in the form of ATP). It is the opposite of passive transport.
Explanation:
This should be correct.
