Which of these statements is true of organisms that reproduce asexually?

a.

asexual reproduction increases genetic diversity in a species.

b.
asexual reproduction involves male and female organisms.

c.
asexual reproduction produces more organisms, but all are genetically identical.

d.
asexual reproduction is always better than sexual reproduction.

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.

blood enters the heart through two large veins, the inferior and superior vena cava, emptying oxygen-poor blood from the body into the right atrium of the heart. as the ventricle contracts, blood leaves the heart through the pulmonic valve, into the pulmonary artery and to the lungs where it is oxygenated.
