Answer:
A metabolic pathway
Explanation:
Biologically, a metabolic pathway is a series of chemical reactions in which the end product of a reaction serves as a substrate (or reagent) for the reaction thereafter, the reactions being interdependent with one another. These reactions are catalyzed by enzymes. The metabolic pathways are fundamental for the maintenance of the cell and consequently of the body's homeostasis.
An example of the metabolic pathway can be seen in the above question where glucose is converted to glucose 6-phosphate by hexokinase. Glucose 6-phosphate then serves as a substrate for the enzyme phosphoglucose isomerase, which converts this reagent to fructose 6-phosphate. Fructose 6-phosphate serves as a substrate for phosphofructokinase, which converts fructose 6-phosphate into fructose 1,6-bisphosphate.

Answer:
B.
Explanation:
Si is an element.
A compound is 2 different elements combined. H2O and NaCl fit this requirement, so they are compounds. They cannot be elements because they are not single elements like Si.
Answer:
The pigment that causes leaves to be green is chlorophyll. ... As chlorophyll goes away, other pigments start to show their colors. This is why leaves turn yellow or red in fall. In fall, plants break down and reabsorb chlorophyll, letting the colors of other pigments show through.
Answer:
a) 600 J
b) 75 W
Explanation:
Force= 400 N, distance = 150 cm = 1.5 m, time= 8s
a) Work is the product of force acting on an object and distance (or displacement). The S.I unit of work is the joules.
Work = force × distance = 400 × 1.5 = 600 J
b) Power is the amount of energy transferred per unit time. It is the ratio of work to time. The S.I unit of power is watt
Power = work/time = 600 / 8 = 75 W
