Answer:
Explanation:
In a eukaryotic cell, almost all transcription occurs in the nucleus and translation occurs mainly at ribosomes in the cytoplasm. In addition, before the primary transcript can leave the nucleus it is modified in various ways during RNA processing before the finished mRNA is exported to the cytoplasm.

1.
The answer is clearly "C" because an adaptive feature is a feature in which a living organism has adapted to, for example:
Millions of years ago, fish and other water creatures evolved to breathe on the surface, and not just in the water. However, this process took many years to adapt to the climate.
2.
I know that this is a gene so I assume, by the wording that this is a length of DNA from another human. Can't particularly explain this very clearly though, sorry. You can read more about it here though by searching about it, sorry I can't put the link as my answer will be removed.
I hope this helps you but if it does not, don't be mean! Message me and I will try my hardest to resolve my answer! :D
1. Regulation of glucose blood levels is an example of negative feedback mechanism.
Negative feedback mechanism is a control mechanism involved in homeostasis maintain, in this case maintenance of glucose blood levels in normal range.
Negative feedback mechanism contains sensory system that detects the changes, control system that responds to change and activates mechanisms of effector system that reverse the changes in order to restore conditions to their normal levels.
• Pancreatic cells-sensors
• Insulin-control system
• Body cells- effector cells
2. Blood glucose levels change throughout the day because of the food consumption, but in healthy individuals levels of glucose are successfully regulated via the mechanism of hormones such as insulin and glucagon in a process called glucose blood regulation.
This tight regulation of pancreatic hormones is referred to as glucose homeostasis. Insulin lowers blood sugar and glucagon raises it.
3. If the beta cells are destroyed by an autoimmune disease (immune system attacks its own cells), there would be no insulin release, and consequently, the glucose blood levels would be increased.
Diabetes type I is a metabolic disorder caused by the destruction of insulin-producing pancreatic beta cells.
The answer is b, decrease the oxygen gas pressure
