1. Exocrine glands are glands that retain ducts to body surfaces. Most glands of the body are exocrine types with ducts connecting to anatomical surfaces; salivary, sweat. Endocrine glands are therefore referred to as "ductless" glands. Endocrine glands are the hormone producing structures of the body; pancreas, thyroid. Ugh, only one answer per question ><

6.Define the term insulin resistance. Explain the relationship between insulin resistance, obesity, exercise, and noninsulin-dependent diabetes mellitus.

I have been diagnosed with this nasty thing. It's when insulin receptors on cells begin to decrease in number and then your body becomes insulin resistant. It loves to store fat and get sluggish. Obese people are often in one of the stages leading to IR. Exercise will help IR. I think the last one is diabetes II in its early stage. IR usually leads to this. Plainly and simply insulin is like a warehouse regualtor. It tells the body to ignore, reject or accept warehouse orders.

Thoughts on Genetic Engineering

Thoughts on Genetic Engineering?
With the new advancements in technology Genetic Engineering is becoming a thing of reality. The Vatican Church officially condemned it with it's new set of sins. The possibility of healing crippled arms and legs could become real if humans research on Bio-modification. Stem cell could treat things such as cancer, Type 1 diabetes mellitus, spinal cord injuries, and muscle damage, amongst a number of other diseases and impairments. So what are your thoughts on the matter?

I'm pretty sure the people who're against it enjoy seedless grapes.
2 :
Why would god even gave mankind intelligence. To utilize DUH. Genetic engineering does good more than harm. It seems religion thesedays are ridiculous, its blockage for prospering society. Why does some theists want all of us to go back to the stone age?
3 :
Do you mean the way that genetic engineering has created food that has no nutritional value which is being marketed now in vast quantities? edit: Which has replaced the food that God made, on the shelves at the grocery store?
4 :
I don't have a problem with it. Though, all those people who want to remain sin-less shouldn't eat seedless grapes or certain apples or even corn on the cob.
5 :
It is never wrong to seek information. It is risky. Most things of of value require a lot of hard work and some risks to obtain. Honesty, compassion, and fearlessness are what are required of the human race to progress and achieve. Not religious dogma.
6 :
Its only a sin if they kill a fetus to use the stem cell. If they use a fetus stem cell which was to be thrown in the garbage anyway, how could that matter? Which if I heard correctly the adult stem cell used without harm to the adult is more effective anyway.
7 :
stem cell research really hits home for me. my wife has MS and stem cells could do amazing things if fundi assholes didnt make the rules. i cant believe in this day and age this is even an issue. its the ultimate example of how religion forces itself on everyone. i hope that in the near future we come to our senses and get stem cell research up and running again. it will help millions of people, whats wrong with that?
8 :
Yeah, and with genetic engineering comes the perfect race. One can already choose the sex of ones baby before they're born; soon we'll probably be able to choose height, hair color, eye color, strength, agility, speed, and they're you have it: the perfect human. And any "specimen" who isn't up to par is aborted.
