Which of the following is a property of epithelial tissue?
a.) epithelial tissue is typically unable to regenerate.
b.) epithelial tissue is innervated.
c.) epithelial tissue does not exhibit polarity.
d.) epithelial tissue contains blood vessels.

B.) Epithelial tissue is innervated.

Explanation:

Epithelial tissue is made up of epithelial cells that make up the covering or lining of body cavities and body surfaces.

The epithelial tissue is innervated by nerve endings. They are practically avascular, so they do not contain blood vessels. Epithelial tissue is known for its capability to regenerate fast. They exhibit polarity called the apical basal polarity.

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.
