Answer:First, we use the polymerase chain reaction (PCR) technique to copy a tiny fragment of DNA so that there is enough to use in gel electrophoresis. Gel electrophoresis uses gel and electricity to separate DNA fragments based on size, creating a distinct pattern that represents an individuals genetic information

Answer:
D). Lisa might experience symptoms of overtraining, like weight loss and increased irritability.
Explanation:
The biggest concern after continuing the program for a few months would be that '<u>Lisa might experience the symptoms associated with overtraining including weight loss and enhanced irritability</u>.' These are the initial symptoms which shows the strain that is being put on the muscles of the body. It may also cause her to face muscle pain, fatigue, a decline in appetite. Gradually, her body would adapt to the schedule and show the desired results. Thus, <u>option D</u> is the correct answer.
Answer:
There is growing evidence to indicate that age-related declines in growth hormone (GH), insulin-like growth factor (IGF)-1, and androgen and estrogen production play a role in the pathogenesis of sarcopenia (an age-related decline in muscle mass and quality). Although GH supplementation has been reported to increase lean body mass in elderly individuals, the high incidence of adverse effects combined with a very high cost has limited the applicability of this form of therapy. The assessment of an alternative approach to enhance the GH/IGF-1 axis in the elderly by using GH-releasing hormone and other secretagogues is currently under way and is showing some promise. Testosterone replacement therapy may increase muscle mass and strength and decrease body fat in hypogonadal elderly men. Long-term randomised, controlled trials are needed, however, to better define the risk-benefit ratio of this form of therapy before it can be recommended. Available data are currently insufficient to decide what role estrogen replacement therapy may play in the management of sarcopenia. Therefore, although the evidence linking age-related hormonal changes to the development of sarcopenia is rapidly growing, it is still too early to determine the clinical utility of hormonal supplementation in the management of sarcopenia.
