Why are vegetable shorting and candles solid at room temperature, whereas olive oil and grape seed oil are liquids? With your answer to that question in mind, how do you think the lipids in the cell membrane of cold water fish compare to warm water fish? Would you expect to see differences in the amounts of fatty acids?

kelp are large brown algae that live in cool, relatively shallow waters close to the shore. they grow in dense groupings much like a forest on land. these underwater towers of kelp provide food and shelter for thousands of fish, invertebrates, and marine mammal species.

e) all of the above

the correct answer is: b. pantala flavescens, because these organisms would have a high level of genetic variation due to sexual reproduction.  

because involves two organisms (parents) whose genetic material combines, sexual reproduction leads to genetic variation in new generations of offspring. the offspring is an unique organism, with new genome, more protected with the higher ability to adapted. this process is fundamental to evolution.
