Essay Instructions: My paper needs to follow my outine and thesis statement: The female reproductive system consists of tow essential parts: the uterus and ovaries. The uterus is responsible for growing the fetus, emission of vaginal and uterine secretions, and permitting male sperm to enter through the fallopian tubes. The ovaries are in charge of producing female egg cells. Ovaries produce hormones which include estrogen, progesterone, and androgens. The aim of this paper is to address the role of the ovaries in the reproductive system as well as its contribution to homeostasis.

3. OVARIES
A)APPEARANCE 1)two almond shaped organs on either side of uterus 2)pale white or yellowish
B)LOCATION 1)suspended by ligaments 2)broad ligaments
C) THREE LAYER OF OVARIES 1)Tunica Albuginea 2)Cortex 3)Medulla
D) NOURISHMENT/REMOVAL OF WASTE 1)ovarian artery/vein
E) FUNCTION: 1)Development of eggs 2)Produce female sex hormones a)estrogen b)progesterone
4. OVARIAN FOLLICLE STAGES
a)follicular phase b)luteal phase
5. HORMONAL REGULATION OF THE OVARIAN CYCLE
a)GnRH, FSH and LH b)how this affects other body systems(endocrine system) c)homeostasis
6. RESEARCH
a)Uterus-what is currently taking place to help us understand this topic.
7) CONCLUSION-tie it within my thesis statement and homeostasis.

No more than one of my references can be from the web. The rest should be from primary literature and other sources. NO PLAGIARISM!

You will write an organism profile based on your literature research. Include all of these topics in your paper:
1. Introduction/background information about the species - Include common and scientific names of the organism, the area you and this species live (country, state, city, etc.), the area?s biome classification, etc.
2. Life cycle of the species - Describe the life cycle of the organism you have chosen. The life cycle of an organism refers to the series of changes in both development and growth from its beginnings as an independent life form up until maturity, when it is able to reproduce. Organisms like bacteria have relatively simple life cycles; however other organisms (e.g., plants) have very complex stages to their life cycle.
3. Structure and Function - Describe the structure and function of at least one major organ system of the species (e.g., digestive system, reproductive system). Choose one system and explain how this organism?s system is structured anatomically and physiologically. Identify any species-specific characteristics or adaptations that are particularly unique to this organism and explain why. If you choose a microorganism, explain how adaptations to its structure and function are unique.
4. Evolution of the organism - Evolution is simply heritable change over time. Sometimes changes from one generation to the next can give individuals an advantage. Specifically a trait that increases reproductive success or survival ability could be advantageous. Include a section in your profile paper about your organism?s evolution. Here are possible ways to research the topic:
a. Conduct a review of scientific literature to understand what is known about your organism?s past evolution. Search key words may include evolution, fossil, ancestor. Often technical reports from wildlife and conservation agencies have descriptions of an organism?s evolution.
b. Summarize research on any adaptive traits. Search key words include adaptation, evolution, trait, and character.
c. Find an article on the family tree or phylogeny of your organism. Summarize the information describing related species. Search key words might include phylogeny, phylogenetic, and genetic analysis.
d. Use the Tree of Life Project to describe the phylogeny of your organism. Start at species, if possible, and trace back to the root. In addition to your summary, include any interesting patterns or unknown data.
5. Additional interest - The diversity of biological organisms is vast. Therefore, if your organism has a particularly interesting aspect about its biology that is not covered in the life cycle, structure and function, and evolution add a section to your paper on that aspect. For example, if your species has an interesting parental care strategy or mating system (i.e., protrandry/protogyny, polygymy, promiscuity, monogamy) you can include that in your paper.
