Martin decided to write his term paper on the topic of animal language. After reviewing the relevant literature on the topic, Martin is likely to conclude that: a. animals can communicate only simple information to other members of their own species. b. the results of several ongoing studies have produced some compelling demonstrations of animal communication and cognition. c. primates are capable of demonstrating a level of language comprehension comparable to that of the typical child in the sixth grade. d. animal language represents no more than operant conditioned responses, and there is no evidence of true animal language. 1 points

option a is correct i.e.

explanation:

in context to the membrane of nerve impulse, the outer membrane of neuron is semi permeable that is only sodium ions can pass through the membrane i.e. smaller ions can pass through the membrane while larger ions cannot pass through it.

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.

hope this .. .
