After school, kai feels hungry and tired. he finds some sugar cookies in the cabinet and finishes the whole package. which statements best describe the role of glucagon and insulin in this scenario? glucagon was secreted by his pancreas before he ate the cookies because his blood glucose was low. insulin was secreted after he ate the cookies because his blood glucose was high. insulin was secreted by his pancreas before he ate the cookies because his blood glucose was low. glucagon was secreted after he ate the cookies because his blood glucose was high. glucagon was secreted by his pancreas before he ate the cookies because his blood glucose was low. after he ate, insulin from the cookies increased his blood sugar levels. insulin was secreted by his pancreas before he ate the cookies because his blood glucose was low. after he ate, glucagon from the cookies increased his blood sugar levels

The correct answer is Glucagon was secreted by his pancreas before he ate the cookies because his blood glucose was low. Insulin was secreted after he ate the cookies because his blood glucose was high.  

At the time of hunger, the blood glucose level decreases, and glucagon at that time, that is, the hormone discharged by the islets of Langerhans increases the level of sugars in the body. The stored glucose in the liver gets discharged due to the presence of glucagon, which eventually elevates the level of glucose in the blood.  

In the given case, when Kai ate the cookies, the level of glucose in the blood got increased and even elevated from the normal level in the blood. At that time, the insulin hormone is discharged from the islets of Langerhans, which helps the cells of the body to absorb the molecules of glucose and thus lowers the concentration of glucose in the blood. Therefore, both the hormones help in monitoring the levels of glucose in the body.  

1) gene flow

- it is described as the transfer of genes from one population to another population so that frequency of gene is increased.

-a zebra migrates to join a different herd of zebras.

2) natural selection

- a mechanism of evolutionary change in which individuals with advantageous traits survive and reproduce whereas the others ( those that can not adapt) eliminate from the population.

-competition for sunlight leads to taller trees.

3) mutation

- permanent change in the nucleotide sequence of dna ( genetic material) that could have harmful or useful consequences.

-the dna of a snake changes to make its venom stronger.

4) genetic drift - it is a random phenomenon ( that occurs by chance such as fire) that results in change in the gene frequency in a small population.    

-a grassfire randomly sweeps through a population of buffalo and kills most of the animals.
