Answer:
Forward chaining as the name suggests, start from the known facts and move forward by applying inference rules to extract more data, and it continues until it reaches the goal, whereas backward chaining starts from the goal, move backward by using inference rules to determine the facts that satisfy the goal.
Answer:
b. by increasing the heart rate
c. by increasing the respiratory rate
Explanation:
Increased activity of skeletal muscles would require an increased supply of oxygen to these cells to sustain the muscle contraction. Muscle cells perform aerobic cellular respiration in the presence of oxygen and produce ATP molecules to be used during muscle contraction. Therefore, there is an increase in heart rate to pump sufficient blood to the skeletal muscles which in turn ensures enough supply of oxygen. Also, there will be an increase in the respiration rate to inhale the required oxygen.
1. proteins
2. essential
3. nonessential

Answer: The statement is false
Explanation:
Addition of concentrated sulfuric acid (H2SO4) to a beaker full of water (H2O) will release heat energy to the containing vessel due to the breakage of strong ionic bond present in the acid.
Thus, it is an evidence of a EXERGONIC REACTION (since energy is released spontaneously). So, the statement is false
Bacteria are decomposers when they are turning the dead material in decaying organisms into nutrients. They become producers when they provide those nutrients for plants.
