Answer the following question given this paragraph: Lactic acid fermentation converts the 3-carbon pyruvate to the 3-carbon lactic acid (C 3 H 6 O 3 ) (see Figure below ) and regenerates NAD + in the process, allowing glycolysis to continue to make ATP in low-oxygen conditions. Since there is a limited supply of NAD + available in any given cell, this electron acceptor must be regenerated to allow ATP production to continue. To achieve this, NADH donates its extra electrons to the pyruvate molecules, regenerating NAD + . Lactic acid is formed by the reduction of pyruvate. Q: What natural destructive element cuts away at rock forming river valleys? Choices: - sediment - lava - air - water A:
water

Answer the following question given this paragraph: The branch of biology that studies animal behavior is called ethology. Ethologists usually study how animals behave in their natural environment. They try to determine the cause of behaviors, how behaviors develop, and how and why behaviors evolve. Q: Which branch of biology studies animal behavior? Choices: - microbiology - anthropology - embryology - ethology A:
(A).
ethology
Ques:Answer the following question given this paragraph: GFCI stands for ground-fault circuit interrupter. GFCI outlets are typically found in bathrooms and kitchens where the use of water poses a risk of shock (because water is a good electric conductor). A GFCI outlet contains a device that monitors the amounts of current leaving and returning to the outlet. If less current is returning than leaving, this means that current is escaping. When this occurs, a tiny circuit breaker in the outlet opens the circuit. The breaker can be reset by pushing a button on the outlet cover. Q: Gfci stands for ground-fault circuit what? Choices: - inspiration - infers - isolates - interrupter A:

Ans:interrupter
Ques: Answer the following question given this paragraph: Spermatogenesis produces four haploid sperm cells, while oogenesis produces one mature ovum. Q: While spermatogenesis produces four haploid sperm cells, oogenesis produces one mature what? Choices: - egg - semen - datum - ovum A:
Ans:
ovum
