Creating sex cells. Result is haploid cell with 23 chromosomes (Half of original 46)

Sperm meets an egg to form a new organism

A fertilized egg

One fertilized egg splits and develops into two babies with same genetic information

Two eggs are fertilized by two sperm

Mitosis begins as zygote (fertilized egg) moves through Fallopian tube

After 4 days, the embryo is a solid ball of 64 cells, called the morula

6-7 days after fertilization the blastocyst attaches to the wall of the uterus (implantation)

-Fluid filled sac for cushioning and protection -Maintains constant temperature -Keeps embryo from drying out

-Organ of nourishment and passing of materials for the baby -Carries away embryo's waste -Made up of vessles from mother and embryo -Prevents mothers blood from mixing with embryos -Prevents harmful substances from reaching embryo

Connects embryo to the placenta

Practicing not having sex.

Sexual activity that does not involve vaginal intercourse.

Shallow, some-shaped latex cup with a flexible ring

Hormonal method of pregnancy prevention. Given to women to prevent an egg from being fertilized

Thin, plastic patch that can be stuck onto the skin and works in much the same way as the pill.

Thin, flexible, plastic stick that a doctor placed under the skin of the upper arm

Permanent form of birth control in men. Tubes that carry the sperm from the testicles are permanently blocked

Permanent form of birth control in women that blocks the women's fallopian tubes

They blur an individual's ability to think clearly. Do the person may act against their values

Most common STD, causes genital warts

Bacterial infection that effects both male and female reproductive systems

Affects vagina, bladder, and urethra, irritation and burning while urination occur.

Higher self esteem, allows for a teen to develop skills

Makes you spend more time smoking and less time with family and friends because you are addicted.

Altered respiration and heart rate, reduced appetite, changes in brain chemistry, and bad breath or smelly hair

Chronic bronchitis, emphysema, lung cancer, oral cancer, heart disease

The amount of alcohol in a persons body, measured as grams per deciliter of blood.

Rate of consumption, gender, body size, amount of food in the stomach

Physical and emotional dependence on alcohol

Brain damage (Destroys nerve cells), liver damage (Reduces ability of liver to metabolize), heart disease (Increases blood pressure and heart rate), digestive problems (irritates tissues lining the digestive system), and fetal alcohol syndrome (Birth defects caused by alcohol consumption).

Family, peers, glamorizations of drugs, and competitive pressure

Barbiturates (Sedate a person when taken in low doses), central nervous system depressants (slow down the activity of the central nervous system), opiates (used to relieve pain, overuse can lead to addiction), stimulates (speed up central nervous system).

Most commonly used drug among teens, causes distorted perception, short term memory loss, loss of motor skills, increased heart rate, and paranoia

Physical risks, distort reasoning, change relationships between friends and family

A peer is one factor that influences us. They can even make you buy something. Its called the "bandwagon". If your friends buy a product, most likely you will follow them and buy it.

Advertising and Media is a huge factor that causes people to buy products. They try to trick us and attract us to buy their product. Advertising even adds professional pictures and free gifts to persuade us.

Budget is important for everyone

Claims are often exaggerated. Many people buy products from claims

You should know how safe products are before buying them

Usually brand names are more expensive then generic names. (Somebody has to pay for the advertising!)

Reliability is a important factor. People might consider a product because they are familiar with brand and they know their friend has it.

If a person you respect or consider trustworthy and knowledgeable recommends a product, you are more likely to buy it.

Many people rely on professional reviews to decide which movie to see or which car to buy. It's a good idea to look up professional reviews of health products too,

It is important to know how to use Internet safely to get information as well as to buy genuine health products and services. The sheer amount of information on some websites can be overwhelming, or it can be confusing and downright contradictory. Sometimes it's hard to figure out which information is trustworthy.

Commercial websites usually promote a business or a service and are among the most common on the Internet. Their Internet addresses end with .com. Some examples are www.google.com, www.msn.com, and www.cnn.com. Since most are commercial enterprises, .com websites may be biased when providing information about products, so you should inspect their claims carefully.

The primary function of organizational websites is to provide information about nonprofit organizations such as nongovernmental organizations (NGOs) and charitable organizations. They usually advocate an individual's opinion or a group's point of view. Their Internet addresses end with .org. Some examples are www.wikipedia.org, www.gp.org, and www.un.org. Because these websites often post opinions and members' point of views, you need to verify the content carefully.

The primary function of educational websites is to provide information about or for an educational establishment or to present information in an educational manner. The educational establishment, such as a college or a university, needs to be recognized and accredited by the U.S. Department of Education to register as an educational website. These websites' Internet addresses end with .edu. Some examples are www.imsa.edu, www.awu.edu, and www.nrc.edu. The information given on educational websites is fairly reliable.

The primary function of governmental websites is to provide information about and for government entities in the United States. Internet addresses of such websites end with .gov, which assures visitors that they are accessing an official government website. Some examples are www.fda.gov, www.state.gov, and www.uscourts.gov. Apart from purely government entities, some technically private organizations that have a formal association with the federal government can also use .gov. For example, the website for the quasi-public Federal Reserve System is www.federalreserve.gov. A .gov website represents the current administration's point of view and can be trusted for providing reliable information.

When you visit a website, make sure to check for 3 things: - make sure you identify the owners or authors of the site. Look for a mailing address and check for the author's credentials and contact information. -You also need to check whether owners regularly update the information provided on the website. - You can also judge the quality of information given on a website by checking how professionally it is presented

-Use a credit card or a debit card for online shopping. Not only can you easily review your transaction on your card company's electronic or paper statement, but it will be protected under the Fair Credit Billing Act, which gives you the right to dispute unauthorized charges. Always shop at reliable websites. It's better to shop at a reliable online store than an unknown one, even if the latter is quoting much lower prices. If a website has a poor layout or incomplete information, think twice about shopping there. -Always read the return policies and find complete contact information for the company on its website. Print out the confirmation record for your online purchases as well as any other information an online store gives you for future reference, such as a reference number or a tracking number for shipments. -Be aware of your rights and register a complaint in case of identity theft or Internet fraud. The Federal Trade Commission (FTC) handles consumer complaints and distributes valuable and up-to-date information on consumer protection.

haploid (half; 23 chromosomes)

Skin, Bone, Muscle Cells

sperm (male), egg (female)

haploid

meiosis

chromosomes double once, cells divide twice, and four cells with half the chromosomes result from meiosis

1.) Nucleus of sperm cell enters the egg 2.) The 23 chromosomes from nucleus of father's sperm cell joins the 23 chromosomes from nucleus of mother's egg cell 3.) Resulting in a cell of 46 chromosomes (nuclei and chromosomes join together)

fertilization

single, multiple (most fertilized eggs develop into single offspring)
