Answer: A
Explanation: All living organisims use energy
The spores produce two types of gametophytes: each microspore develops into a microgametophyte (male gametophyte), which ultimately produces male gametes (sperm), and each megaspore produces a megagametophyte (female gametophyte), which ultimately produces female gametes (eggs).
Answer: anaerobic respiration
Explanation:
Anaerobic respiration is simply respiration in the ABSENCE OF OXYGEN.
A positive nitrate test mean Escherichia coli reduces NO3 (Nitrate) to NO2 (Nitrite). This is based on its ability to produce nitrate reductase enzyme that catalyze the reduction process. And note that this reaction occurs in the ABSENCE OF OXYGEN.
This makes E. coli an ANAEROBE ( an organism that can survive in the absence of oxygen)
