Energy that is not utilized for work or heat transfer is converted to the chemical energy of body fat containing about 39 kJ/g.
AnnZ [28]

Answer:

m=107.8g

Explanation:

Hello,

In this case, for the given information, we can compute the gained grams by firstly compute the energy consumed by 14.3 h of being sit relaxed and 9.70 h  of sleeping:

E_{sit}=120\frac{J}{s}*\frac{3600s}{1h}  *14.3h*\frac{1kJ}{1000J} =6177.6kJ\\\\E_{sleep}=83\frac{J}{s}*\frac{3600s}{1h}  *9.70h*\frac{1kJ}{1000J} =2898.36kJ

Then, we compute the energy used that day:

E_T=10000kJ-2898.36kJ-6177.6kJ=4203.28kJ

Finally, the mass by considering the consumed fat:

m=\frac{4203.28kJ}{39kJ/g} \\\\m=107.8g

Regards.

Which of the statements is correct? A. Water leaves the descending limb of the loop of Henle through active transport. B. NaCl e
Ivenika [448]

Answer:

The best answer is "E"

NaCl leaves the ascending limb of the loop of Henle through active transport.

Explanation:

The loop of Henle is a U-shaped portion of the tubule that conducts urine within each nephron. It's principal function is the recovery of water and sodium chloride from the urine.

The ascending limb is impermeable to water. NaCl is pumped from the tubule into the interstitium in the ascending limb by active transport. This active transport enables the kidney to establish an osmotic gradient which enables the permeability of water and urea thereby allowing the kidneys to concentrate the urine.

A surface area of a sphere can be approximated as follows: surface area=4r^2 where the radius of the sphere is a constant that i
Illusion [34]

48 square unit

Explanation:

Given parameters:

Surface area of sphere = 4πr²

value of π = 3

radius of sphere = 2

Unknown:

Surface area of sphere = ?

Solution:

To solve we input the given parameters in the formula for the surface area of the sphere.

         S. A  =  4πr²

  r is the radius of the sphere

  π is a constant whose value is 3

    S.A = 4 x 3 x 2² = 48 square unit
