Amy made the table shown to describe two different relationships between animals. organism interactionsrelationship a relationship b both organisms benefit one organism benefits, the other is unaffected which of the following statements is most likely correct? relationship a is parasitism and relationship b is competition. relationship a is competition and relationship b is parasitism. relationship a is commensalism and relationship b is mutualism. relationship a is mutualism and relationship b is commensalism.

Option (4).

Explanation:

Biological interactions are important among the organism that helps them to survive in their environment. Biological interactions may be harmful or useful for the organisms.

Mutualism may be defined as a type of interaction in which both the species are benefited from each other. Amy should include relationship A in mutualism. Commensalism may be defined as the type of interaction in which one species is benefited and other organism is neither benefited nor harmed the individual. The relationship B is involved in commensalism.

Thus, the correct answer is option (4).

relative dating involves things like higher layers are most recent than rocks lower in the sequence. this can be extended to the known sequence of fossils. rocks containing rabbit fossils are later than those containing dinosaur fossils.  

absolute dating methods mainly use radioactive elements that have known rates of decay and produce recognizable products. for example potassium 40 decays to produce argon. once a rock has solidified the argon is trapped. by measuring the argon and potassium0 you can get an accurate number for the age.  

some other methods are good for archaeological ages. dendrochronology involves recognizing the sequence of tree rings. the orientation of magnetized particles in baked clay can be used to date a fire.
