That's not a question, but I guess I'll just vomit some information at you and hope I hit a target.
First of all, not true. Unless you're talking multiple choice kind of thing.
Room temperature is 20 degrees C / 68 degrees F / 293 degrees K
At this temperature, most elements are solids, but
Mercury and bromine are liquids
Hydrogen, helium, nitrogen, oxygen, flourine, neon, chlorine, argon, krypton, xenon, and radon are all gases.
Interdependence. Animals in a food chain/web are dependent on eachother for survival or death
The stronger survived and the weaker passed on... Those with a weaker immune system had trouble with sickness and usually ended up passing on but those with strong immune systems were stronger and healthier and lived.
Answer:
a. Only the DNA of β cells contains the gene for insulin; only the DNA of chief cells contains the gene for pepsinogen
Explanation:
As stated in the question above, insulin production is exclusive to β cells in the pancreas. This is because only these cells have a gene that manages the production and excretion of insulin within an organism. Similarly, only the main cells of the stomach have the capacity to produce pepsinogen, which indicates that the gene responsible for managing this production is unique to these cells.
