Answer 2

Hi frou...(been a rough couple years lol) Dont know that I am back, but am for a time anyway. As a devout christian ( I know, here we go again, yes?) and speaking for myself, I find the study of these subjects interesting. even fascinating. In my healthier days, before the spina bifida caught up with me, I prepared herbal teas for folk's ailments . I learned how primarily from two people. My grandfather, and my greatgrammie's sister, who was native american. Dont think I even knew the word biology for quite a few years after Grampa started teaching me at about the age of six or seven. When I realized the "borrowed time" aspect of my life was catching up with me I brought as many herbs home from the woods and fields and started a garden out back. And yes, there were several that could not adapt and still needed to be foraged. Did not hear the word psychology till even after I heard biology ( was introduced to biology in high school and loved the study of it ) Again , it had no impact on me except I could say, "oh that's what they call it" Interesting but all the therapy or introspect I ever needed or will need , for me, is found in the Bible where the one who is the first and greatest counciler of all, and for all times, is to be found as is the answer to every question or problem I ever, ever had or will have. I feel that for some people psychology can be a tremendous help and as for myself, I confess to calling pastor a time and again even for a shoulder to cry on. Thing is tho, psychology, in my opinion, has become abused and caused more problems then the ones that caused folks to seek help in the first place. Also many people who desperately feel they need that help cannot find it for lack of funds. Thing that intriques me most is that those same folks give up on themselves and life for the lack of psychologists. Sad. I do run on , dont I dear? LOL Hope you have been well and happy during my vaca from comps. Penumbra

I don't want to sound rude, but you really should just open your biology book and read the appropriate sections. After you've read the material that you should, you ought to be able to answer these questions by yourself...

IF you have a specific question that you can't come up with the answer for, I'm sure folks would be willing to help you understand. But to just ask for the answers to your homework is pretty bad...
