It would take a week or seven days because one pound is about 3,500 calories and 500x7 is 3,500. Hope that helps :)
Answer: to defend itself
Explanation:
This natural reaction prepares you to either flee or protect yourself in dangerous situations. Your heart rate increases, your adrenal gland releases cortisol (a stress hormone), and you receive a boost of adrenaline, which increases energy. This fight-or-flight response occurs in the alarm reaction stage.
The answer is D.
The basic metabolism depends on height, weight, age, sex and thyroid activity. Outside temperature and climatic conditions also influence significantly. Basal metabolism decreases with age from 2% to 3% per decade after adulthood. Children, on the other hand, have a basal metabolism that is twice as high as that of adults.
This is likely due to peripheral vasoconstriction. This happens in order for the body to retain heat longer in order to protect the body from hypothermia. The skin would act as an insulator of the organs and water. Also, when this happens, it would allow more of the oxygen to be transported to the oxygen sensitive organs like the brain and the heart.
I don't even think so because waste has to come out
