The correct answer for this would be generator, an alternator is just a miniature belt driven generator, which means that when your car is running the belt attached to your shaft spins the alternator which converts the kinetic energy into electricity which charges your battery.
Answer:
the 2nd and 4th
Explanation:
they contain more than one molecule due to them being different elements
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.
Answer:
It's a duplication........
Answer:
Autonomic regulation of heart is via two reflex centers that are found in medulla oblongata
Explanation:
Medulla oblongata contain long stem that makes the upper part of brain case and this is a cone shaped structure which is responsible for autonomic regulation like controlling heart rate,vomiting,respiration,breathing etc.
The heart rate is controlled by autonomic nervous system that are mainly sympathetic and parasympathetic nervous system that releases hormones like catecholamine (epinephrine and non epinephrine) which helps in controlling the heart rate.
Medulla oblongata mainly connects the brain with the spinal cord that are responsible for responsible for the autonomic functions which contain -
Controlling the ventilation via signalling system regulated by chemo receptors which detects change in acidity of the blood.
Acts on cardiovascular centers.
Controlling the reflex centers like vomiting,coughing,sneezing,swallowing etc.
