Answer:
Choice C., High blood glucose levels can result from an overproduction of insulin
Explanation:
Blood sugar levels are regulated by two pancreatic hormones—insulin and glucagon. When blood sugar levels increase, insulin is released (beta cells of the pancreas), it binds to its receptors and consequently increase glucose uptake by cells, which effectively lowers blood glucose levels. On the other hand, when blood sugar levels decrease, glucagon is released (alpha cells of the pancreas), it binds to its cell receptors, and causes glucose to be released into circulation, thereby increasing blood glucose levels.
Answer:
A general decrease in transcriptional activation
Explanation:
When acetyl groups are added to histone proteins by acetyltransferase enzymes, the 30-nm chromatin fiber will not be formed because the proteins are prevented from doing so. This further destabilizes the chromatin structure and allows the occurrence of transcription. However, raising the cells to 40°C does not allow the acetyltransferase enzyme to function and hence the acetyl group will be hindered from being added to the histone protein which is the main target of the enzymes. Thus, transcription activation will be blocked because the chromatin and nucleosomes would remain stabilized.
This picture represents humoral immunity, please read through it, and if you dont understand which option is your answer then i would recommend you read more about this topic, if you want it to be done fast, you can read this http://www.s-cool.co.uk/a-level/biology/immunity/revise-it/the-third-line-of-defence
I hope you can come up with the answer on your own as it will be a good thing for you in your future exams :)
Surely i can help you if you dont understand something so just ask :D
