B. is the correct answer. - <span>Pyruvate is decarboxylated, acetyl reacts with coenzyme A, forming NADH + H+
During the Krebs Cycle ( also known as the Citric Acid Cycle) the Pyruvate molecule decarboxylated ( meaning it lose a carbon a carbon dioxide molecule) and forms the molecule acetyl- coenzyme A also known as (acetyl CoA). Furthermore, NAD+ ( nicotinamide adenine dinucleotide) reacts with H+ to form NADH </span>
Dew drops can be found on <em>grass</em> or a <em>car</em> parked outside but not on other materials such as the <em>sidewalk</em> because; The <em>nighttime temperature on grass and the car went below the dew point, but the temperature of the concrete did not drop enough to reach the dew point level</em>.
Definition:
- The dew point is simply defined as the temperature below which the water vapour in a <em>given volume of air at a constant pressure will condense into liquid water. </em>
- More specifically, the dew point is the temperature at which the air is saturated with moisture.
From the definition above, it is evident that the fact that the nighttime temperature on grass and the car went lower than the dew point <em>temperature</em> is responsible for the <em>condensation of water vapour on grass and the car as opposed to the case in Concrete.</em>

D .Terrestrial biomes are distinguished primarily by their product
<span>Chloroplasts contain chlorophyll, which is a green pigment that can change the light energy of the sun into fuel. Plants take carbon dioxide from the air and water from the soil and change them into sugars. ... The function of the roots is to absorb and store water and nutrients from the soil and to support the plant.</span>
