<span>Carbohydrates are more easily metabolized than lipids. However, on a gram-for-gram basis lipids provide cells with more energy. Lipids are the sources of the highest amount of energy, but they are much more difficult to process by our bodies compared to things such as carbs.</span>
        
             
        
        
        
The correct answer is C. Fermentation makes NAD+ needed to keep glycolysis going. The other options are inaccruate since:
for A: there are types of fermentation that does not produce carbon dioxide like Lactic acid fermentation
for B: many types of fermentation only occurs in the absence of oxygen (anaerobic process)
for B: respiration produces around 36 ATP while fermentation only generates around 2 ATP
        
             
        
        
        
Given:
The heat content of the pizza is  Q = 500 kcal 
The volume of the cold water is V = 50 L
The mass of a liter of cold water is 1 kg.
Calculate the mass, M,  of cold water.
M = (50 L)*(1 kg/L) = 50 kg 
The specific heat of water is
c = 4.184 kJ/(kg-K)
Also,
1 kcal = 4184 J, therefore
Q = (500 kcal)*(4184 J/kcal) = 2.092 x 10⁶ J
Let ΔT = increase in temperature of the cold water, °C (same as K).
Then
Q = M*c*ΔT
or 
ΔT = Q/(M*c)

Answer: The temperature increases by 10 °C (or 10 K)
 
        
        
        
It works with other organs of the digestive food after it leaves the stomach and to absorb nutrients. The entire digestive system works together to turn the food you eat into energy.
        
                    
             
        
        
        
Answer:
Sheep carrying out respiration
Explanation:
Because the sheep is exhaling carbon dioxide into the air
