How is the hunger hormone of an overweight or obese person different from that of the host ?

Answers

Answer:Ghrelin mRNA level rises significantly after estrogen administration in cultured stomach cells [65]. Estrogen has been well documented to regulate food intake by modulating meal size and to stimulate growth hormone secretion. These effects may be partially mediated through ghrelin.  

How does ghrelin cause obesity?

Ghrelin stimulates the brain, which leads to an increase in appetite, and it slows metabolism and decreases the body's ability to burn fat. Ghrelin also favors the amassing of fatty tissue in the abdominal area.

What's an example of consuming candy in moderation? Group of answer choices Eating a candy bar once a week Eating a candy bar every day Avoiding candy bars at all costs No answer text provided.

Answers

Answer:

Eating a candybar once a week

Explanation:

Eating a candy bar once a week is an example of consuming candy in moderation.  Therefore, option (1) is correct.

Eating a candy bar once a week is an example of consuming candy in moderation. Consuming candy in moderation means enjoying treats like candy occasionally and in small amounts, rather than consuming them excessively or on a daily basis. It allows for occasional indulgence while still maintaining a balanced and healthy diet.

By limiting candy consumption to once a week, individuals can satisfy their sweet cravings without overloading their diet with excessive sugar and calories, promoting better overall health and well-being. Moderation is key to maintaining a healthy lifestyle and preventing the negative effects of consuming too many sugary or high-calorie treats. Therefore, option (1) is correct.

How are health education ,population education and environment interrelated on science and technological aspect?​

Answers

Answer :

[tex] \boxed{ \text{Relationship \: of \: science \: and \: technological \: aspect \: with \: other \: aspects \: of \: human \: population \: and \: environment}}[/tex]

↦ Human health , population and environment are interelated on the basis of science and technological aspects developed by human beings. Health is broadly studied in medical science and many scientific achievements affect human health in positive as well as negative ways. Some inventions like x-ray , ultrasonography , computerized tomography ( CT ) scan and various other scientific technologies are widely used in diagnosis and treatment of different diseases. These new technologies are useful in tackling human diseases and health hazards. But the use of some technologies is harmful to human health and the environment as well. Experimentation of nuclear power , development of different weapons , production of pollutants etc can be taken as some of the adverse effects of science and technology on health and the environment.

Some of scientific technologies are useful in the conservation of the environment. Identification not environmental problems and evaluation of the environmental status have been easier due to the development of technologies. In this way , health , population and environment are interrelated on the basis of science and technological aspect.

Invention and experimentation not some science and technological objects sometimes cause massive destruction of people and environment. Nuclear bomb explosion by USA at Hiroshima ( on 6th August 1965 ) and Nagasaki ( on 9th August 1945 ) in Japan are eminent examples of brutal destructive effects caused by technological development on human and the earth. The radioactive effects of the explosion are still inhibiting natural development of life at the affected areas even after several decades.

Science and technological aspects have both positive and negative impacts on human health , population and environment. Hence , they are closely related with each other.

Can someone who doesnt have the body of what they identify as be considered as transgender?

For example, I have a body of a female and I look like a female yet I identify myself as a male.

Just because you have a certain body type doesn't mean that you are not who you identify as. Even if you have a more feminine body, you can still identify as a male. Surgery is not what makes you transgender. Hope my explanation helped

many people transition without surgery. you can changed the way you dress or you're name and pronouns. only 3% if the trans community has had surgery. but if you don't your still very much valid in the trans/lgbtq+ community
