Layers of sediment forming on the ocean floor is a form of deposition.
as insects became exposed to pyrethroids, toxicity of pyrethroids weakened over time. which means that Most insects had the allele for pyrethroid resistance, but it remained masked. The allele for said pyrethroid resistance, evidently increased throughout the population.
has this helped?
The correct answer is C. Fermentation makes NAD+ needed to keep glycolysis going. The other options are inaccruate since:
for A: there are types of fermentation that does not produce carbon dioxide like Lactic acid fermentation
for B: many types of fermentation only occurs in the absence of oxygen (anaerobic process)
for B: respiration produces around 36 ATP while fermentation only generates around 2 ATP
