Nancy suffer from insulin dependent diabetes mellitus and is on insulin therapy. You administered her insulin dose orally and realized hours that she still hyperglycaemic despite your administration of the right dose. Explain what might have led to this?

 Insulin is a hormone, which is secreted by the pancreas to regulate the sugar levels in the bloodstream.

Explanation:

Insulin is a protein hormone if take orally, will get digested in the digestive tract, it will not be able to affect the target site of action.

Insulin gets denatured in the digestive tract. Thus it will not be able to control the blood sugar levels.

Nancy has taken the insulin dose orally, the insulin will get denatured in the digestive system, it will not function and Nancy will remain hyperglycemic after the consumption.

gametes or germ cells are haploid cells (example: sperm and ova) containing only one set (or n) number of chromosomes and autosomal or somatic cells are diploid cells containing 2n number of chromosomes.

answer: decrease

a limiting factor is the one which decrease the abundance, distribution and causes extinction of the population of species in a ecosystem. here, predators including hawks, owls and snakes are the limiting factor for the population of mexican free tailed bat.   although bats are nocturnal animals as they forge for food at night these predators also may remain active during night which can decrease the population of the mexican free-tailed bats. also, these bats eat only one type of insects that are moths. the food can also be a limiting factor as all 400 members are dependent upon same type of food needs that are moths. the decrease in the moth population can cause decrease in population size of the mexican free-tailed bats.

therefore, the scenarios will most likely to decrease the population size of the mexican free-tailed bats.
