Which is the MOST accurate statement about cells?(A)The number of cells is a constant across organisms, but the types of cells vary for specialization.(B)Cells are not only building blocks for body tissues, but also players in the reproduction of organisms.(C)Because cells share the basic job of making copies of themselves, they all have the same DNA.(D)Cells are identical on their surfaces, other than the cell walls that plants have and animals do not.

desert perennials often survive by remaining dormant during dry periods of the year, then springing to life when water becomes available. most annual desert plants germinate only after heavy seasonal rain, then complete their reproductive cycle very quickly.

c: warm water flows from the western tropical pacific toward south america. that should be the right answer! hope it .

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.
