The impacts of currents vary from one body of water or landform to another. How can inlets, like the one shown on the map, be impacted by currents?

A) Currents have significant impact on inlet weather.
B) Currents prevent boats from drifting out of inlets.
C) Currents can change the shape of an inlet's opening.
D) Currents can prevent pollution from entering inlets.

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.

not necessarily. higher fitness requires the organism to be reproductive successful. for example, an organism at age 10 with 15 offspring is much more fit than an organism at age 15 with only 5 offspring.
