How do cells become cancerous?

accelorated cell division

Explanation:

the cells grow faster, this is why many use chemotheropy it kills all fast growing cells

Cell multiplication

Explanation:

When a cell strats growth and multiplies too much it becomes a cancer. This results in tumor.

unicellular organisms, like bacteria, are able to perform all life functions within one single cell. multicellular organisms need many different types of cells to carry out the same life processes. each of these special types of cells has a different structure that it perform a specific function.

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.
