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
Complex organisms need cells that can perform many different functions. they need to be supported on a cellular level. Without specialized cells you they won't be able to perform different functions.
Answer:
C. Cutting down forests.
Explanation:
Carbon dioxide is an inorganic gaseous molecule with the chemical formula, CO2. It is naturally released into the atmosphere via a lot of processes. However, CO2 is the most important greenhouse gas as it contributes the most to the global warming effect of the Earth.
The effects of an increase in CO2 concentration in the atmosphere is as follows:
- increase in water contamination and floods
- ocean acidification
- reduction of cold-related deaths
However, the cutting down of forests is not an effect of an increase in CO2 concentration but rather a cause.
I believe we obtain the cells of our test subject from DNA testing
hope it works!!
