Answer:

C. The red mites were resistant to the effects of the insecticides.

Explanation:

The increase in the population of the red mite due to the application of the insecticides shows that red mite are resistance to the effect of insecticides because the insecticides did not decrease the population of the red mite but the predator of the mite die and decrease in population. This insecticides have no effect on the red mite so for reducing the red mite population the citrus grower should use another pesticide that kills red mite.

Alex_Xolod [135]

Answer:

The correct answer is option c) "It is necessary to have a completely functioning pentose phosphate pathway for a tissue to synthesize ribose phosphates".

Explanation:

While the pentose phosphate pathway is the most common way at which a tissue synthesize ribose phosphate, it is false to affirm that it is necessary for ribose phosphate synthesis. Tissues have alternatives to the pentose phosphate pathway to synthesize ribose phosphate. For instance, the nucleotide salvage or the salvage pathway allows tissues to synthesize ribose phosphate from intermediates in the degradative pathway for nucleotides.
