...Week 1 Assignment: The Sperm and the Egg Nathaniel Morris PSY/265 3/18/2012 Nicole Pansey Week 1 Assignment: The Sperm and the Egg Many of us have heard about the birds and the bees. Most parents find this story to better illustrate how conception happens. When a young child asks their parent “Where do babies come from”, a parent may find it hard to look in their young child’s eyes, and describe exactly what happens. The actual scientific process may be harder to explain, but will be more useful for the child when they get older. It would probably be more effective with a variety of visual aids, and preparation in order to present this to an adolescent. Deciding at what age to tell your child the scientific version should depend on the parent. The “birds and bees story” may be more appropriate for a younger child, and the scientific version can be more explained when they are a little more mature. A girl should know about the sexual reproductive system when she starts menstruating. If she is not taught properly, she may not understand what is going on with her body, and may wind up pregnant at an early age. In order to explain the scientific version, first, you would have to start out by explaining the immediate male and female body parts that are involved; the penis and vagina. The inner part of the vagina consists of two ovaries, the cervix, and the uterus that are all connected to the uterus by the fallopian tubes. These are all structures that make up the...

...Running head: THE SPERM AND THE EGG Assignment: The Sperm and the Egg 1 YOUR NAME PSY/265 DATE NAME OF PROFESSOR The Sperm and the Egg It has certainly been a wild adventure on my way to the infundibulum, which serves as the outer component of a female’s fallopian tube (Nevid, Rathus & Fichner-Rathus, 2005). My name is ‘Egg’. In fact, all of my siblings share the same exact name! I am anxiously awaiting my friends to arrive. They are all named ‘Sperm’ and are considered to be male germ cells. It has been quite a long time since I last saw them. I have been preparing for their arrival for quite some time and cannot wait to see them! It was a daunting task to be here in the first place. The ovary in which I live near had roughly 400,000 other eggs; however, when she was younger, she experienced puberty; as a result, only 1% of us made it to transformed into ripened ova. I am finally able to be the ova responsible for suppressing the development of additional ova in order to be discharged during the ovulation period (Nevid, Rathus, et al., 2005). As soon as I made my journey away from the ovary, I travelled all of the way to the fallopian tube. I am now still in the fallopian tube waiting for my friends to come over. It took a great amount of effort for me to journey through the fallopian tube; as such, ovulation occurs roughly every two weeks prior to menstruation. The tube I travelled through is only four inches in length; however, in order for me to be...

...Kingdom Plantae All land plants experience alternation of generations. Two distinct phases exist: A diploid sporophyte alternates with a haploid gametophyte. (In reality these phases represent two body forms of the same organism). The gametophyte produces gametes (eggs and/or sperm). A diploid sporophyte produces spores by meiosis. Sporophytes and gametophytes look distinctly different from one another (heteromorphic). Mosses and Ferns Phylum Hepatophyta (Liverworts) The plants are called liverworts because they look like a human liver. They are very small and you’ll find them growing on rocks that are next to freshwater streams. Activity: Examine Marchantia. The body of this plant is called a thallus. The thallus is the gametophyte portion of the life cycle. Identify the gemma cups. Inside the gemma cup is gemmae. The gemmae get dislodged by splashing water. If they land on a suitable substrate, they grow into new thalli. [pic] kingdomplantae.blogspot.com Phylum Bryophyta (Mosses) Mosses grow on trees, rocks and soil. They have a wide variety of human uses, the most common one being a soil additive to potting soil and as a major component of peat, which is used for fuel in some parts of the world. Notice that the sporophyte remains attached to the gametophyte. The gametophyte continues to provide nutrition for the...

...Itohan Ehineboh Access to Higher Education: Nursing and Midwifery Human physiology 16/12/2015 Word count: 752 & bibliography Ismail Abdullah This assignment will discuss about the Prokaryotic and Eukaryotic cells by comparing their structure and function: It will talk about the similar components they have and their function of the two cells (prokaryotic and Eukaryotic) and then it will talk about the different components and their function in the cell. It will relate the structure to function in two specialised eukaryotic cells and the structure of the cell membrane to its function of movement of substances into and out of the cell. Regarding to the cell theory all living things are made of cells and all organisms may be classified as prokaryotes (before nucleus) or eukaryotes (true nucleus). Prokaryotes was developed first, they are small (size 1 to 10um) and they consist of one cell (unicellular) and it has no nucleus but instead it as a nucleoid which contains the genome (DNA of the cell). (Boundless 2015) (Look figure1) Eukaryotes come from prokaryotic cells and they are large (size 10 to 100um), highly structured, they consist of many cells (multicellular), has a nucleus which is the brain of the cell and it is enclosed in a nuclear envelope. The prokaryotic and Eukaryotes both have a Cell Membrane, Ribosomes, Cell Wall (in Eukaryotic it is present only in Animals) and Cytoplasm. The cell membrane is a thin flexible bilayer round the outside of all cells...

...In this assignment I am going to be outlining all the gross structures of the main body systems and I would also be saying what the system is made out of with a diagram. Main body system • Skeletal System • Muscular System • Nervous system • Respiratory system • Digestive System • Male Reproductive System • Female Reproductive system • Cardiovascular system • Urinary system • Endocrine system 1. Skeletal system The skeletal system is muscle that is connected to the skeletal to make a part of the mechanical system which moves the limbs and other parts of the body. The skeletal also relates the cartilages and joints of the human body which then creates the human skeleton. It is one of the main and important systems in the body. The joints are very important because they allow different types of movements at different locations to happen. However there are three components; • Bones • Cartilages • Joints Bones: Bones is a tough and frim form of connective tissue. It is the responsibility is to almost all strength of skeletal. Bone is the mineralization factor. Bones are highly mineralized with calcium salts Cartilages: The cartilage is a form of the connective tissue however it is not as tough and frim as the bone and the main difference in the cartilage and bone is the mineralization factor. This is because the bones are highly mineralized with calcium salts whereas cartilages are not. Joints: the joints are important components of the human body...

...Unit 4: Development through the life stages for Health and Social Care P1 – Describe Physical, Intellectual, Emotional and Social development for each of the life stages of an individual This assignment will describe the different factors of development throughout stages of life, beginning from contraception through to the final stages of life. It will highlight the four factors like, Physical, Intellectual, Emotional and Social development. Conception – This is the stage where life is made and is done so when a male sperm fertilises the female egg this normally happens in the fallopian tube after insemination at this point the fertilised egg makes it way to the uterus (womb) this is when the stage is called pregnancy. Millions of sperm are ejaculated by a man during orgasm, just one sperm is needed to fertilise the egg. In some cases the ovary can release more than one egg, dependant on how many eggs will be fertilised will determine the number of embryo’s this could be anything from twins to eightuplets. Physical As this is the initial stage of life there is not much physical development within this stage only of when the sperm intergrades with the egg and creates the embryo. Dependent of the chromosome will determine the baby’s sex. If the male’s sperm delivers an X chromosome then the child will be a baby girl but if a Y chromosome is delivered then this will produce a baby boy. This is the only physical change that takes at this stage. Intellectual No intellectual...

...Sam King BWVW 102-001 March 1, 2015 Worldview Application Assignment Abortion Abortion has been a very controversial topic in American history ever since the court ruling in the case Roe vs. Wade. The court ruled that abortion is okay when the heath of the mother is at risk. Another case that increased the number of abortions was Doe v Bolton. The courts expanded the definition of health for the mother to include familial, financial, psychological, and well-being as determined by her physician. The contemporary issue that surrounds abortion is when does life begin because that questions decides whether you are killing a human or not. Many Christians that hold a biblical worldview will say it begins when the egg meets the sperm. A non-Christian would say it begins at a certain trimester and or when the baby is born. These two views can be worded as pro-choice and pro-life. The biggest issue that separates the two is whether it is morally right or wrong to kill a baby in the womb which then raises the question of when life beings. Abortion will continue to be a very controversial topic all throughout the world and the Untied States, but can be stopped with people that care about life and what it means to be human. A question that needs to be answered when talking about life and death is what is the meaning to life. The bible makes it very clear as to what the meaning of life is. Man is to seek after God always and keep his commandments as it says in 2 Timothy 4:1-5 ...

...In this assignment I will be going through all of the life stages than an individual will go through. These stages are: • Conception. • Pregnancy. • Birth and Infancy 0 – 3 years. • Childhood 4-9 years. • Adolescence 10-18 years. • Adulthood 19-65 years. • Older Adulthood 65 years + • Final Stages of Life. Conception is when the ovary must have released an egg, this is then drawn down the fallopian tube towards the uterus. This usually occurs halfway through the menstrual cycle. In the process of these, the lining of the womb is preparing for the occurrence of a pregnancy and thickens its lining by increasing blood flow to the thinning blood mucus to allow sperm to enter. During sexual Intercourse, between a man and a woman sperm is ejaculated into the vagina. Once the sperm enters the uterus, it tries to find the egg which is at the lower end of the fallopian tube. Male semen contains several million sperm, but only one will be needed for conception, and that single sperm cell contains the father's genetic contribution to the baby. Each sperm contains 23 chromosomes and each egg contains 23 chromosomes. The sperm can swim, and need to be able to do so as they have to move through the cervix, into the uterus and along the fallopian tubes. During sexual intercourse millions of sperm are ejaculated by a man. The sperm swims through the uterus and fertilizes the egg in the fallopian tube. The sperm and egg combine to form a ball of cells. After 36 hours the egg starts...

...Complete all three parts and answer all questions. Download Graphic Organizer for answering all questions and genetics exercises in this assignment. Part I: Genetics – From Genes to Proteins, Mutations Background: DNA represents the architectural blueprint for all living systems, encoding specific instructions in the sequence of its four nitrogen-containing base pairs that are necessary for building the organism. During the process of transcription, the information in the DNA codons of a gene is transcribed into RNA. A change in the DNA sequence, for example as a result of a "mistake" during DNA replication, is defined as a mutation. Mutations may result in a change in the "blueprint," which may then change the resulting protein product. Assignment details for part one: Transcribe and translate EACH of the three following DNA gene sequences. Turn these in using the graphic organizer. The letters represent the DNA N-base sequences of the genes. The first is the original gene. The next two are mutations of the original. Note that the changes (mutations) are shown in red.

...Abortion Crystal Estell EN1320 Assignment 2.2 Abortion is one of the most controversial moral issues of our age. Although pro-choice and pro-life arguments centering on the morality of the issue are already well stated, the other more practical arguments on this subject have been underreported. I. What is an abortion? A. Why would a person decide to abort? 1. Is it right to be pro-life or pro-choice and then why. 2. Who should make this decision? B. Should the government be involved or should this be only the decision of one person? 1. Should the law protect the ones that cannot speak up for him or herself? 2. Or should the law be kept out completely and leave it up to the parents, or maybe just to the mother. II. Abortion is legal in the US and many other countries. A. Therefore, by creating a new abortion law we might put additional risk on women/mothers willing to abort somewhere else. 1. So does it make sense that abortion is not restricted by any law? 2. However, abortion not being restricted by law is being abused by many as they use it as contraception. B. So would it be dangerous if abortion were forbidden in the US? 1. How many abortions are done in the US in a year, month, and day? 2. How many are done worldwide? III. America, the land of freedom, therefore should there be the free choice even for abortion? A. What are the risks of having an abortion? 1. What are the possible complications of...

Lesson 10 - Natural Family Planning By the end of this chapter you should be able to: Describe the history of natural family planning. Describe the variants of natural family planning. Explain the motivations behind the use of natural family planning. Differentiate between natural family planning and pharmaceutical contraceptive measures. What is Natural Family Planning? Often, a couple may want to engage in sexual intercourse (extensively) and at the same time avoid pregnancy. In cases such as these a number of strategies are employed specifically to this end. The term contraception literally means "against conception", so contraceptive measures either prevent pregnancy from occurring or prevent it from progressing after it has occurred. Needless to say, there are profound implications at many levels when addressing contraceptive issues. Without a doubt, contraceptive strategies are in widespread use, and even considered to be mainstream in many places. Contraceptive measures are classified as being behavioral, barrier, or chemical methods. Behavioral methods are the subject of this lesson. The various artificial forms of barrier and chemical strategies directed toward contraception, pertaining to the most common use of that term, is the subject matter for the next lesson. In some cultures and in some religious traditions, the use of artificial chemical or barrier contraceptive...
