Once the sperm burrows it's way into the egg, the egg has been fertilized creating what is called an ovum. ]]> 2016-10-07 00:43:31 UTC https://padlet.com/meyer_k/ma2hplouxelb/wish/128999297 meyer_k https://padlet.com/meyer_k/ma2hplouxelb/wish/129259859 2016-10-08 01:17:10 UTC https://padlet.com/meyer_k/ma2hplouxelb/wish/129259859 meyer_k https://padlet.com/meyer_k/ma2hplouxelb/wish/129259921 The ovum contains 23 chromosomes of the mother and another 23 from the father. Chromosomes contain the DNA of the parents. ]]> 2016-10-08 01:20:18 UTC https://padlet.com/meyer_k/ma2hplouxelb/wish/129259921 meyer_k https://padlet.com/meyer_k/ma2hplouxelb/wish/129259953 2016-10-08 01:22:08 UTC https://padlet.com/meyer_k/ma2hplouxelb/wish/129259953 meyer_k https://padlet.com/meyer_k/ma2hplouxelb/wish/129259996 The sperm makes it's way through the ovum's cytoplasm, cellular material surrounding the ovum's nucleus, and finally into the nucleus. The zygote forms which is when the "sperms chromosomes become a part of the nuclear material" (Broderick & Blewitt, pg 41).]]> 2016-10-08 01:23:16 UTC https://padlet.com/meyer_k/ma2hplouxelb/wish/129259996 meyer_k https://padlet.com/meyer_k/ma2hplouxelb/wish/129260355 2016-10-08 01:34:35 UTC https://padlet.com/meyer_k/ma2hplouxelb/wish/129260355 meyer_k https://padlet.com/meyer_k/ma2hplouxelb/wish/129260379 Twenty-two of the mother's and father's chromosomes are matched leaving the 23rd pair to determine the sex of the baby. Because the mother's 23rd chromosome has a matched X chromosome and the father has an unmatched XY chromosome, the baby will get one X from the mother and either another X or Y chromosome from the father. If the 23rd contains 2 X chromosomes the sex will be female, whereas XY would make a male.]]> 2016-10-08 01:35:17 UTC https://padlet.com/meyer_k/ma2hplouxelb/wish/129260379 meyer_k https://padlet.com/meyer_k/ma2hplouxelb/wish/129260611 2016-10-08 01:44:21 UTC https://padlet.com/meyer_k/ma2hplouxelb/wish/129260611 meyer_k https://padlet.com/meyer_k/ma2hplouxelb/wish/129260628 2016-10-08 01:44:51 UTC https://padlet.com/meyer_k/ma2hplouxelb/wish/129260628 meyer_k https://padlet.com/meyer_k/ma2hplouxelb/wish/129260662 2016-10-08 01:46:47 UTC https://padlet.com/meyer_k/ma2hplouxelb/wish/129260662 meyer_k https://padlet.com/meyer_k/ma2hplouxelb/wish/129260676 Chromosomes divide, duplicate, and pull apart to opposite sides of the nucleus. This cellular division is called mitosis (Broderick & Blewitt, pg 42). The two new cells that are divided, divide into 4 new cells before dividing again into 8 cells, and so forth.]]> 2016-10-08 01:47:31 UTC https://padlet.com/meyer_k/ma2hplouxelb/wish/129260676 meyer_k https://padlet.com/meyer_k/ma2hplouxelb/wish/129260798 2016-10-08 01:52:25 UTC https://padlet.com/meyer_k/ma2hplouxelb/wish/129260798 meyer_k https://padlet.com/meyer_k/ma2hplouxelb/wish/129260812 Implantation occurs once the organism moves down the fallopian tube and into the uterus.

By the 9th week the fetal period begins. Besides hereditary influences, the environment plays an important role in the development of a healthy pregnancy and baby. The nutrients ingested and social interactions that the mother has will have an impact during and after birth.]]> 2016-10-08 02:06:20 UTC https://padlet.com/meyer_k/ma2hplouxelb/wish/129261123 meyer_k https://padlet.com/meyer_k/ma2hplouxelb/wish/129262054 2016-10-08 02:44:44 UTC https://padlet.com/meyer_k/ma2hplouxelb/wish/129262054 meyer_k https://padlet.com/meyer_k/ma2hplouxelb/wish/129262069 2016-10-08 02:45:23 UTC https://padlet.com/meyer_k/ma2hplouxelb/wish/129262069 meyer_k https://padlet.com/meyer_k/ma2hplouxelb/wish/129262135 If the baby is exposed to teratogens during and after birth, it could be detrimental to the baby's health and future development. Teratogens are harmful substances or agents (alcohol, tobacco, cocaine, marijuana, lead, PCB's etc.) that the fetus is exposed to during the pregnancy (Broderick & Blewitt, pg 53). The placenta serves as a pathway and barrier; it surrounds the fetus. Blood and nutrients are passed to the fetus. The placenta cannot keep the fetus safe from teratogens.  ]]> 2016-10-08 02:48:38 UTC https://padlet.com/meyer_k/ma2hplouxelb/wish/129262135 meyer_k https://padlet.com/meyer_k/ma2hplouxelb/wish/129262438 2016-10-08 03:04:39 UTC https://padlet.com/meyer_k/ma2hplouxelb/wish/129262438 meyer_k https://padlet.com/meyer_k/ma2hplouxelb/wish/129262492 Growing continues after the baby is born. Synapses takes place where different parts of the brain make new connections with the many neurons being reproduced (Broderick & Blewitt, pg 63). As learned in the TED Talk, the baby may be able to recognize certain noises or tastes that they heard while in the womb. The amount of affection, attention, proper nutrients, the environment the baby grows up in, and social interactions all impact the child's future growth, health, and learning.]]> 2016-10-08 03:07:19 UTC https://padlet.com/meyer_k/ma2hplouxelb/wish/129262492
