Answer: The circulatory system is a network consisting of blood, blood vessels, and the heart. This network supplies tissues in the body with oxygen and other nutrients, transports hormones, and removes unnecessary waste products that do not belong in the nervous system or even body.
Explanation:
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:
correct option is E) horizontal gene transfer
Explanation:
solution
we know here that phenomenon account for movement of these genes is horizontal gene transfer because we know Horizontal gene transfer are primary mechanism for spreading of antibiotic resistance in the bacteria
and
in many mechanism some are
(1) transformation
(2) transduction
(3) Gene transfer agents
and that Gene transfer agent is virus and it like element encode by host that is occur in alpha proteobacteria
and
we know that implant of one to other plant can transfer chloroplasts , mitochondrial and entire cell nucleus contain the genome to the potential makes new species
as that we can say here correct option is E) horizontal gene transfer
Answer:
Plankton and Algae
Explanation:
Adult zebra mussels feed by filtering large amounts of plankton and detritus from the water. Each mussel can filter one liter of water per day! Zebra mussels thrive in nutrient-rich water which supports healthy populations of plankton.
