3) a. Spermophilus variegates
b. rock squirrel
c. mutualism
d. Squirrels are very popular, you see them when you are camping and even when you are just looking in your front yard. They can eat small bugs and even the food that we put out for them. Over time they have been hunted more and more for there beautiful skin that they have.

11) a. Bos taurus
b. dairy cattle
c. predation
d. . These cows are part of the food chain. Therefore, I deem this relationship a predation one. This cow is so important to our culture these days.

Unit 3 Lab

I decided to do a model of a working leg. There are about five important bones in the hip and lower leg. First is the pelvis and it goes all the way to the tarsals. The body has so many very important bones and i think that this is the most important limb of bones we have in our bodies.


In this picture I have all of my materialsThis is a picture of the tibia as the big bone on the right and the fibula, the smaller bone on the left. At the top there is a bone called the tibial tuberosity which is part of the tibia. The top of the fibula is called the head of fibula.

This is a picture of the knee to the top of the femur. The femur is the longest and strongest bone in the body. The knee cap is acually called the patella. The head of the femur articulates with the coxal bones at the acetabulum, and the short neck better positions the legs for walking.

This is an overview picture of what is together so far from the fibula to the top of the femur

This is a picture of the coxal region. This region is the pelvis which supports most of the body and lets the body walk.

This is an overview picture of the pelvis all the way down to the bottem of the fibula.

This is a picture of the bottem of the fibula. The markers are the toes and the candle is the talus. The tarsal bones, one of which can move freely where it joins the tibia and fibula.

This is the overview shot of the work limb, the pelvix girdle and lower limb.

Compendium Review 7

*Human Life Cycle

-mitosis

-meiosis

-male reproduction system

-female reproduction system

-control of reproduction

-fertilization

-embryo development

-fetal development

-pregnancy and birth

-development after birth

*Mitosis

-duplication division

-takes place during growth and repair of tissues

*Meiosis

-reduction division

-only in the testes of males during production of sperm

-in the ovaries of females during the production of eggs

-chromosomes are reduced from the normal 46 called diploid down to 23 which is called haploid

*Male reproduction system

-testes are the primary sex organ that are contained in the scrotum

-vas deferens pass into the abdominal cavity, where it curves around the bladder and empties into an ejaculatory duct

-urethra is what the ducts are called

-semen is what you call the sperm that ejaculate from the penis

-seminal vesicles lie at the base of the bladder, and each has a duct that join with a vas deferen

-prostate gland is a single, donut-shaped gland that surrounds the upper portion of the urethra just below the bladder

-bulbourethral glands are pea-sized organs that lie posterior to the prostate on either side of the urethra

*Testes

-seminiferous tubules contain within lobules

-spermatogenesis is the production of sperm

-sertoli cells, support, nourish, and regulate the process of spermatogenesis

-sperm that is mature has three parts:

--a head

--a middle peice

--a tail

-chrosome stores enzymes needed to penetrate the egg

*Female Reproduction System

-ovaries lie in a shallow depression

-eggs are produced by the ocaries

-zygote is a formation, fertilization,that usually takes place in the oviduct

-implantation occurs-the embryo embeds in the uterine lining, which has been prepared to receive it

-pap testis to detect cancer of the cervix

-endometriom is the lining of the uterus

THE OVARIAN CYCLE

THIS PICTURE IS THE FEMALE HORMONE LEVELS

The ovarain follicle produces increasing levels of estrogen, which cause the endometrium to thicken during the proliferative phase of the uterine cycle. After ovulation and during the luteal phase of the ovarain cycle, LH promotes the development of the corpus luteum.

THIS IS A PICTURE OF THE EFFECT OF PRENANCY

If pregnancy occurs, the corpus luteum does not regress. Instead, the corpus luteum is maintained and secretes increasing amounts of progesterone. Therefor, menstruation does not occur, and the uterine lining, where the embryo resides, is maintained.

*Birth control methods

*birth control pill

-contain a synthetic estrogen and progesterone

-fools body into acting like it is pregnacy has occured

-thickens the cervical mucus preventing sperm entry into the uterus

*abstinence

-100% effective

-best way to not get pregnate

*female condum
-is fitted for the vagina

-prevents sperm from entering

-79% effective

*male condum

-latex that fits over the penis

-prevents sperm from going into the vagina

-prevents against STD's

-89% effective

*Fertilization

-sperm swim with their tails

-the head of the sperm makes its way through the cornoa radiata

-acroaomal enzymes digest a porton of zona pellucida

-sperm binds binds to and fuses with the eggs plasma membrane

-sperm nucleus enters cytoplasm of egg

-cortical granules releaseenzymes

*Pre-Embryonic Development

-pre-embryonic development encompasses the events of the first week, as shown

-morula is a compact ball of embryonic cells that become a blastocyst

-inner cell mass surrounded by an outer layer of cells

-chorion emphasizes the complete dependence of the developing embryo on this extraembryonic membrane

*Embryonic Development

-begins with the second weeek and last until the second month

-by the second week the embryo inbeds itself into the uterus

-ectopic pregnancy can not succeed because an oviduct is unable to support it

-

By the third week the nervous system and the heart begin to develop

Who should reproduce?

Who should reproduce? A good question correct? Well in this essay it is going to get answered. You are going to hear different view points and lots of facts so you can choose for yourself what you think about it. People want to talk about other countries but I want to focus on our country. You may be asking why and i have a great anwser, we live in this country and i think that we should be educated about our country before we try to undestand other countries. So lets talk about our country and what we need to do or what problems we can talk about.
There is an organization called the Zero Population Growth that has been doing research in Africa and other countries. I want to take what they have said and incorperate that into our country. They said that is every couple had only two children than it would be just like replacing ourselves. I agree when we die than we have our two children that will replace us. So in the end our poplulation will never rise. It also goes for people that dont have children and choose to adopt. If everyone only adopted one child than our country would eventually over years would decrease in poplulation.
Should we be worried about other countries and there poplulations or what they eat or dont eat? I agree that to keep our world all even and every country where they should be, that we should be aware but i dont think that we should focus more on there population than ours. We should be trying to make sure that in 50 years our population isnt decreasing and that disease is all under control.
Recently there was a news article saying that in todays world we dont have as many children as we used to 20 years ago. I think that things have changed in a way that people want to adopt more than they did 20 years ago. To me thats weird having your own child is a wonderful experience and for those people that truly cant have children why do we always have to resort to adopting from other countries when here in our country we have millions if not more children that dont have homes or live in foster care. People say that foster care is like having a home but in reality its not it is a temporary situation.
So do you think about all the different veiw points? Who do you side with? Do you agree with adoption, busting our population or do you truly believe that we should put all our focus on other countries and there populations? Its all your opinion and frankly i think that most of what was said is an opinion as well besides the numbers.
Who should reproduce? Thats the question that i hope i have anwsered for you. It is an important issue that needs to be delt with. Hopefully though this essay people will read and try to change the future. We are the future and we control how to really change it so hopefully it works.

self reflection 4

REGARDING YOUR OWN PERFORMANCE
1. What were the three aspects of the assignments I've submitted that I am most proud of?
I am very proud of my compendium reviews i feel like i am getting the hang of them. The labs are also getting easier to me and i enjoy them more. Of course the ethical issues are so exciting for me to write, i love that all the issues were interesting to me so i felt i did a great job with them.
2. What two aspects of my submitted assignments do I believe could have used some improvement? My big labs, I feel that maybe i didnt fully understand them 100% of the time. Also I had a lot of trouble getting my pictures onto blogger so i dont think that you got the full project that i did. Blogger never let me comment on other peoples ethical essays and that was fustrating and i felt that i had to take a 5 point loss each unit
3. What do I believe my overall grade should be for this unit? a low B or a high C because i tired my hardest, but i was sick and in a weird position that i couldnt put 100% into this class and that upsets me.
4. How could I perform better in the next unit? Just try to get as much done as fast as i can but still but in my best work.


REGARDING THE UNIT (adapted from Stephen Brookfield, University of St. Thomas "Critical Incident Questionnaire")
At what moment during this unit did you feel most engaged with the course?
Unit 4 i think because i am pregnate and it was crazy to see and read all that i did because i didnt know most of it.
At what moment unit did you feel most distanced from the course?
unit 1 i have had the same problem with this unit in high school and i just dont really know what it is.
What action that anyone (teacher or student) took during this unit that find most affirming and helpful? just my teacher was sooo understanding and made me feel so much less stress and i am just really thinkful that there are people out there in this world that can a teacher and a person and i really i dont know what i wouldve done without his help.

What action that anyone (teacher or student) took during this unit did you find most puzzling or confusing?ummm some of the comments on my blogger were a little like did you really read my essay or no.

What about this unit surprised you the most? (This could be something about your own reactions to the course, something that someone did, or anything else that occurs to you.)
Maybe i would say the units were set up in a surprising way....easy to go about and do your work.

Lab 8

This is a graph of Madagascar


This is a graph of Africa

1. What was your high fertility rate country and what was its fertility rate?

Africa- fertile rate was 5.90 children at 54.9 years
Africa's high- 6.5 children at 57 years
Madagascar fertile rate- 6.81 children at 53.1 years
Madagascar high- 7.8 children at 55 years

2. What was your low fertility rate country and what was its fertility rate?
Africa's fertile rate-5.90 children at 53.1 years
Africa's fertile low rate-5 children at 50 years
Madagascar's fertile rate-6.81 children at 53.1 years
Madagascar's fertile low rate-6 children at 51.2 years

3. The initial demographic "shape" of your high fertility rate country should have been a pyramid, with high population in young age groups. Explain why high fertility rate results in a high percentage of young people in the population. How does this affect future population growth?
There is a higher percentage of younger people due to the life expectancy. They are expected to live shorter lives than people in America live. People in these countries have many children so at most points there are more children running around than there are adults. They have poverty and issues with the water and food so the adults tend to feed the younger children and the adults tend to get sick and eventually die off quicker than adults. This is a big issue because if you have a world that has manly younger people than at younger and younger ages they will be giving birth and it could eventually kill off there country.







4. Your low fertility rate country might have had a more oval-shaped curve with high population in middle age groups. This is especially exaggerated if the fertility rate is below 2.00. Explain why low fertility rate leads to lots of middle-aged people.
It can happen when couples aren't having enough children. For example if every home only has 1 child than the population is going to have more older people and over time it is going to be very hard to reverse that.

5. Write ten adjectives or descriptive phrases for what you might expect life, people's attitudes, conditions on the streets, etc. will be like in each of those situations. Imagine a situation with lots of middle-aged and older people in the population and write ten quick "brain-storm" descriptors for you think it would be like (Prescott, Arizona?). Then do the same for a situation with lots of children in the population.
-over run
-not enough life
-more sick
-more needy
-less quiet
-more hospitals
-more nurses
-less schools
-less cars on the road
-more retirement homes

LOTS OF CHILDREN
-more schools
-more kid activities
-less retirement homes
-more cars on the road
-more accidents
-more drinking
-more cops
-more jobs
-less complaints
-more fast foods

Lab 7 : Fetal Development

Week 5

Your embryo is growing rapidly and the hearts middle layer start to form. This is a very important time due to its all about the heart and it needs to be developed properly.

Week 13

Your baby has fingerprints now. Baby has working kidneys and urinary track but are still developing. Your chances for a miscarriage are safer now and continue to get safer. This is a great significance because of the miscarriage issue.


Week 18


You can now start to feel the baby. The baby is now about 5 to 5 in a half inches long and weighs about 7 to 8oz. I think this is a significant event because this is the beginning for you and your baby to start bonding together.





Week 20

Your baby is starting to swallow which is a great sign of the digestive system. Your baby moves throughout the day and is growing greatly. At this point in your pregnancy you may start to feel you are getting bigger or have crazy cravings. This is significant because you are just weeks away from knowing the sex of your baby and on the road to bonding with your partner and baby.


Week 24

Eyebrows and eyelids are now in place. The baby practices stretching out so movement is more apparent. The babies taste buds are developing and skin is soft and wrinkly. Its important to keep up your nutrients because baby needs them at this point.


Week 26

The lungs are beginning to develop, so this is a big part of development for the baby. This is important that everything goes good during development because if anything goes wrong it could lead to problems for the baby later.

Week 27
The baby has more brain tissue now so there is more movement. The baby is starting to get the hiccups but might only last a few moments but its a good sign to look for. This is significant due to your babies movement is very important and make sure you tell your doctor they'll want to know for later visits if the activity seems to weaken or strengthen.







Week 29

The baby is starting to need a lot more calcium and other vitamins. This is an important part of pregnancy because you need to make sure you eat more cheese and drink more milk so you and the baby can stay healthy and well. The baby is going to take it from you so if you don't have enough than you will be the only that is losing it and that's not good.


Week 36

This is time that your baby is now safe to be born if you were to go into labor. You baby's kidneys are developed and the lungs are about 90% developed. Your baby has shed all the hair on its body and is probably in a head down position. This is a significant point because if your baby were to be born they would be okay as long as there weren't any other complications.







Week 40

This is significant to me in that this is the only real safe time to give birth and everything is a 100% developed. Your baby may come out with a cone-shaped head due to the pressure during birth but its normal and will go away.
