Human growth hormone is genetically engineered and inserted into human tissue to simulate growth in people with dwarfism. what are possible concerns that scientists have about the long term effects of this process?

Scientists must be concerned about the impacts it causes on normal people due to aging.

Explanation:When a healthy human takes the growth hormone they do not any side effects or symptoms at the early stage. Once they start aging they have joint and muscle pain in legs and arms earlier than other people of their age and also result in diabetes, blood pressure and heart and lung diseases.

The Human growth Hormone can also cause tumors in brain and also indulge in growth  and development of Cancer Cells in people who has cancer or had been diagnosed before.So these are the main side effects that scientists should rectify in Human Growth Hormone.

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.
