The presentation of an 18-month-old with hereditary fructose intolerance (HFI), deficiency of aldolase B and low blood glucose levels is due to accumulation of fructose-1 phosphate and the inhibition of glycolytic-gluconeogenic pathways.
Explanation:
Hereditary fructose intolerance leads to deficiency of fructose-1-phosphate aldolase enzyme. This enzyme deficiency leads to accumulation of fructose-1 phosphate in the liver. Fructose-1 phosphate inhibits the action of phosphorylase enzyme which monitors the glycogen to glucose conversion. Since glucose formation is reduced, hypoglycemia and lactic acidosis takes place accounting for the patient’s low blood sugar.
Answer:
True.
Explanation:
Rotenone is a broad spectrum pesticide and insecticide and is also considered as a non-selective piscicide.
The action mechanism of the rotenone has been described below -
It interferes with the electron transport chain which occurs in mitochondria of the cells. Here the transfer of electrons from complex I to the ubiquinone is inhibited by the rotenone. As a result, ATP formation with the help of NADH is also inhibited. When electron transport fails, oxygen in the cell is reduced to oxygen radical which further damages DNA and other components present in the mitochondria.
The choices can be found elsewhere and as follows:

cocci
rod shaped
spirilla

I believe the correct answer is the last option. The morphology represented is a spirilla. Hope this answers the question. Have a nice day.
Red and White blood cells:
These are produced by the stem cells in the bone marrow. There are two types of stem cells for producing white blood cells - Myeloid stem cells (producing phagocytes such as neutrophils and monocytes - the undeveloped version of macrophages) and Lymphoid stem cells (responsible for production of lymphocytes such as B and T cells).
