Match the bacterial type with its proper definition. An answer choice can only be used once. A. Requires oxygen, but is toxic at atmospheric concentrations B. Can use oxygen for growth or can grow without it C. In fluid thitoglycollate medium, shows growth only at the top area of the medium D. Oxygen is completely toxic to it A. microaerophile B. facultative anaerobe C. obligate aerobe D. obligate anaerobe E. aerotolerant anaerobe

the most common energy conversion is from kinetic energy to potential energy, and then from potential energy to kinetic energy.

later on comes the heat energy, mechanical energy, and other energy conversions.

this energy conversion is so common that we can find it in our day to day lives as well.

- one of the most common energy conversions involves the changing of potential energy to kinetic energy or kinetic energy to potential energy

the backbone of the dna and rna compound is sugar phosphate.

step 1: nitrogen fixation- conversion of atmospheric no₂ into forms useful to plants by lightning, bacteria, and cyanobacteria.

step 2: nitrification-process of converting ammonia to nitrite or nitrate.

step 3: assimilation-plant roots absorb new form of nitrogen.

step 4: ammonification-conversion of organic nitrogen to ammonia by bacteria involved in decomposition.

step 5: denitrification-bacteria turns the decomposed matter back into n₂o, which is released into atmosphere; repeat cycle.
