I want to work in the field of Bionics when i get older. I hope to create working artificial limbs controlled by the brain and cochlear implants, etc.

What type of college degree would i need? I have done some research, but the answers were vague, ranging from chemical, mechanical, biological, and biomedical engineering degrees.

I was hoping someone would be able to give me a more definitive answer. Thanks!

I don't really understand it but find it interesting. I am an engineer so if someone is a little scientific I won't burst into tears, but my knowledge of environmental science is somewhat minimal. I work for a municipality.

I need to write a 700 word account that speculates what might happen to the four Earth systems if the heat loss from inside the Earth reduced by half. the account will need to explain:what the four earth systems are, how the systems interact with each other , what might happen to each system in this scenario and how likely this scenario is. You can either use the numbered referenced system or the 'Bradshaw et al 1998'type of system with an individual reference to each citation in the reference list.

Can anyone help with this. Can anyone some a useful link. Or share his own knowledge with me please. Specially on numbered referenced system .. Plz help

Gastric bypass, tummy tuck, & Lap Band surgery. What are the benefits & the risks, & which one is the safest? I know my oldest sister died from complications from a tummy tuck, & I heard that Gastric Bypass is bad, too. But I was told that Lap Band was the best & the safest. & is it true that when a woman has a Cesarean Section, that's an AUTOMATIC tummy tuck? That's what my twin sister told me, & she had 3 C-sections with all her kids.

When I was living in New York, the doctor strongly emphasized & advized me to get Lap Band surgery, & he told me that Medicaid & Medicare would pay for it. I'm like 175 lbs. overweight for my height. & also, he said that after I've lost my desired weight, I can get the lap band taken out at any time. & he said I'd lose 100 lbs. Would I lose 100 lbs. instantly with that or would it take time?

**Sorry for so many questions but I need to get all of them answered.
