The answer would be (C) i believe.
Human can produce a maximum mechanical power of 1/3 hp (horse-power).
Horse power is a unit of power, it equals 746 watt (watt is also a power unit, known to be equal to a joule per second)
So:
1 ph = 746 watt = 746 J/s
1/3 ph = 248.6 J/s
we're looking for the calories, so
1 joule = 0.239006 calories
So human produce a maximum mechanical power of:
248.6 J/s = 82.88 calories per second.
We're looking for the number of calories consumed in three hours, so:
82.88 cal/s = 82.88 cal/s * 3600 s * 3 = 895200 calories = 895.2 kilocalories (food calories).
The number of food calories is 895.2 food calories
Answer:
Estrous cycles give females repeated opportunities to become pregnant throughout their productive lifetime. The cycle is regulated by the hypothalamic-pituitary-gonadal axis, which produces hormones that dictate reproductive events.
Explanation:
The sympathetic and parasympathetic are responsible for the body's spontaneous actions, such as breathing, heartbeat, digestion, body temperature control.
<h3>What is the function of the sympathetic and parasympathetic nervous systems?</h3>
The sympathetic nervous system acts in an opposite way to the parasympathetic one, preparing the organism to react in situations of fear, stress and excitement, adapting the functioning of several internal systems to a high state of readiness.
In this case, the Sympathetic nervous system also controls body functions that are rarely conscious and parasympathetic nervous system the part of the autonomic nervous system responsible for stimulating actions that allow the body to respond to calm.
