Objective 9: Compare and contrast bonds types

Lord have mercy, bonds have been drummed in my head through my BIO career and honestly I really do not want to talk about it but since it is an objective I have to. 
A ionic bond are formed between a metal and non-metal due to the greedy-grabby nature of the non-metal. Covalent bonds are formed two non-metals and have equal sharing.
Hydrogen bonds are the weakest of the bonds and are polar covalent and share bonds but do not share them equally.

Objective 59: Appreciate the microscopic anatomy of the liver

As I learned in lab, the microscopic anatomy of the liver has hepatocytes and sinusoids. This website is good to view before a practical, because they have a variety of slides to learn from.

Objective 2: Apply critical and integrated thinking skills

In labs I would say this particular objective came in handy because you always have to think when you are doing an experiment, and you get help from others to say what there views or opinion or knowledge is on the lab or questions.  Plus during BIO 100 I had to do a two part lab practical.  One part was written the other was your typical practical.  The written part consisted of making a lab report on basically a little bit of information that was in the pamphlet she gave.  I would say me getting a 73/75 on it showed I applied critical and integrated thinking skills.  Here's a note my lab teacher had me thinking all the time because she would always say "how do you think" or "why do you think" certain things do the things they do etc.

Objective 8: Demonstrate correct care and safe use of instruments, equipment, and living organisms

I really do not know how to go about this objective.  There are no digital artifacts I found useful.  Only thing I can say is that the teacher never said anything to me about not using tthe equipment or instruments incorrectly.  We did not use any living organisms that I can recall.  When using the microscopes I held it by the the neck and the base.  When dissecting the cat, I used gloves, apron, the right tools, dissecting tray and goggles.  I never broke anything so I say I did everything the correct way whenever I stepped foot in the lab.

Objective 6: Use written and oral communication skills to explain scientific concepts

I think this blog will attest my written communication skills. This blog is about reflecting on how I learned the objectives throughout this blog.  I know some of the objectives are short and direct and in my opinion to the point.  Also the purpose is not to teach but to reflect.  However, in reflecting sometimes I believe I have fallen into teaching. Honestly though on some of these objectives you can not help but teach because that is the only way to get your point across on how you learn.  I really do not see myself possibly using oral communication.  I left that for my teacher, she has oral communication on lock.

Objective 7: Analyze factors that can affect cellular activities

What does not affect cellular activities.  I did not need to take any BIO classes to know that threre is a whole crop of things that can affect cellular activities, although I would not have said the words cellular activities.  The body can go out of whack by a number of things such as pH, glucose levels, circulation, temperature, drugs, stress, disease, etc.  So I really did not need any book or website to teach me about this.  I have been on this earth for almost 27 years and I have seen and done a alot of things.  Just everyday life and seeing things and things happening to me.  Let me put it this way life has taught me about this.  Only thing being in class has taught me is to correctly name what is going in peoples body.

Objective 3: Solve for unknowns by manipulating variables

This objective was achieved when we found the pulse pressure and the mean arterial pressure in lab.  There is not much to talk about on this objective.  This was literally doing a math problem.  I would not say I learned or memorized anything.  It is quite easy to remember how to get your pulse pressure.  Next time anyone wants to know there pulse pressure only thing you need to do is take your blood pressure and subtract your systolic from your diastolic.  Also if you want to know your mean arterial pressure which I doubt no one will even know what that means the equation is your diastolic plus pulse pressure divided by three.

Objective 1: Understanding Homeostasis with the effect of aging and stress on each system

For me to understand this objective I went on the internet and found a great site that helped me better comprehend the subject matter.  The site is http://www.novelguide.com/a/discover/eoa_04/eoa_04_00390.html To be honest I used the internet a great deal this semester. Being in BIO three semesters straight with the same teacher who hones in on homeostasis on just about every lecture, you come to remember the effects of stress very vividly especially when she gives you details into her life with her dealing of stress and what it did to her body.  For example, there was a point in her life where she was handling a lot of stress due to the fact that her daughter was injured in a car accident.  In dealing with that she wasn't compelled to eat, so her digestive system was off track.  She lost a lot of weight she always said it was the best diet she have ever been on.  Her skin got pale and malnourished, her hair probably was not in the best of shape.  In the regards to aging form what I gather the longer we live on this earth I am assuming stress mounts.  People will go through deaths, not being able to pay their bills, injuries.  All these examples could bring about long-term stress.  Which in turn can cause hypertention, hyperglycemia, the immune system can get suppressed, and retention of sodium and water.
