Ovulation takes place when one mature egg leaves a woman's ovary and travels to the Fallopian tube.

         Fertilization
This stage begins when a man's sperm attaches itself to a woman's mature egg in the Fallopian tube. When the sperm meets the egg and penetrates it, this is when the genetic make up of a baby is created and the sex is determined.

The fertilized egg now becomes a Zygote...]]> 2018-05-02 15:08:59 UTC https://padlet.com/sandone_b/fntxihiq6aly/wish/257291046 sandone_b https://padlet.com/sandone_b/fntxihiq6aly/wish/257291071 *9 month gestation period

- Week 0-2, zygote goes from fertilization to implantation

-Week  3-8, embryo's organs & body structures are forming

- Week 9-birth, period of the fetus. During these weeks the reproductive system forms, brain & nervous systems develop and there is weight gain

* For normal prenatal development to occur, proper nutrients from the environment and the genome must code correctly in the proper time frame]]> 2018-05-02 15:09:02 UTC https://padlet.com/sandone_b/fntxihiq6aly/wish/257291071 sandone_b https://padlet.com/sandone_b/fntxihiq6aly/wish/257291295 Birth usually occurring during weeks 37-40 of pregnancy.  A Baby is considered premature if he/she is born before 37 weeks.

           Sage 1
-Lasts 12-24 hours
-Contractions are 12-20 minute apart & last up to 1 minute long
-Stretching of the cervix begings
-Cervix dilates to 4 cm.

          Stage 2
- The head of the baby moves through the cervix & birth canal
- Contractions are every minute & lasting a minute
- This stage ends with the birth of the baby

           Stage 3
- Placenta, umbilical cord and membrane are expelled (after birth)
- lasts several minutes]]> 2018-05-02 15:09:26 UTC https://padlet.com/sandone_b/fntxihiq6aly/wish/257291295 sandone_b https://padlet.com/sandone_b/fntxihiq6aly/wish/257291867 A zygote is formed when the sperm fertilizes the egg. A zygote contains 46 chromosomes, or 23 from the female and 23 from the male. Chromosomes are found in the nucleus of cells, they carry the genetic information and together form genes. The 23rd pair of chromosomes is the sex chromosome, this pair determines the sex. The match created by the 23rd pair of chromosomes is called a Kara type.

A male zygote is a mismatched X and Y chromosomes. 

A female zygote is determined by the matching large X chromosomes.   ]]> 2018-05-02 15:10:18 UTC https://padlet.com/sandone_b/fntxihiq6aly/wish/257291867 sandone_b https://padlet.com/sandone_b/fntxihiq6aly/wish/257291995  The zygote will continue to travel down the Fallopian tubes and makes its way to the uterus during implantation. This journey normally takes up to two weeks. Finally, Implantation occurs when the zygote attaches itself to the uterus.. At this point the zygote becomes an embryo.]]> 2018-05-02 15:10:28 UTC https://padlet.com/sandone_b/fntxihiq6aly/wish/257291995 sandone_b https://padlet.com/sandone_b/fntxihiq6aly/wish/257292143 - Brain development starts around 2 week when the baby is an embryo.

- At month 4, the different parts of the brain begin to form

- From months 5-9, neurons are increasing rapidly]]> 2018-05-02 15:10:41 UTC https://padlet.com/sandone_b/fntxihiq6aly/wish/257292143 sandone_b https://padlet.com/sandone_b/fntxihiq6aly/wish/257292430 After birth, neurons will continue to increase and the brain will grow. The neurons will now make connections called synapses. This is because there is a significant amount of learning done. Experiences will also help to weed out some neurons, as you are born with many more neurons than you need. ]]> 2018-05-02 15:11:09 UTC https://padlet.com/sandone_b/fntxihiq6aly/wish/257292430
