Anabolic steroids were initially prescribed by doctors for medicinal use. Anabolic-Androgenic steroids, especially in the form of testosterone, were given to males with abnormal hormone levels or to induce puberty. Steroids may also be prescribed to help with bone growth and development and the loss of appetite. But as with all good things, moderation must be strictly enforced. One of the major
d= 104mg (The final step was dividing in the order of operation and this would be the dosage for the child after solving the expression.) As instructed for this discussion I will show the age of the child based upon the dose of medicine he was prescribed. We can use the same literal equation, however we are solving for a different variable. This time we are using 300 for the adult and 100 for the child a. d=D(a+1)/24 (Cowlings rule formula) 100=300(a+1)/24 (I substituted 100 for d and 300 for
Procedure: We used 3 test tubes per “run”. Tube 1 was filled with 0.1 ml of guaiacol, 1.0 ml of peroxidase (Turnip extract), and 8.9 ml of distilled water. Tube 2 contained; 0.1 ml f guaiacol, 0.2 ml of Hydrogen Peroxide (H2 O2), and 4.7ml of distilled water. Tube 3 was filled with 1.0ml of peroxidase and 4.0ml of distilled water. These three tubes acted as our baseline.
We learned many facts about condoms such as if you put it on the wrong way you shouldn't turn it around and use it since there might by slight traces of sperm on the end and impregnate your partner. One disturbing but yet very informative lesson was the part on the diseases and STDs. Learning about harmful diseases is very important so we know what the signs of an STD is, to be able to diagnose ourselves with what our problem is. Also when learning about the diseases we learn how there are transmitted and how we can prevent them. The last important lesson from the Human Sexuality unit that I'll remember is all the body parts of the male and female sexual reproductive organs.
In this debate, there are two main camps: those who say co-sleeping increases the risk of SIDS, and those who say it promotes breast feeding, which decreases the risk of SIDS. Both sides have numerous studies and papers out, supporting their stance on the issue. The American Academy of Pediatrics and the Consumer Product Safety Commission both say never to sleep with your infant, while UNICEF refuses to support blanket recommendations against bed sharing (Spangler, 2001; Mace, 2006). Some of the questions asked include; does co-sleeping increase the risk for SIDS; does co-sleeping encourage breastfeeding; does breastfeeding decrease the risk of SIDS; and who is actually sleeping with their infants. In this paper I am going to analyze some studies on co-sleeping, breastfeeding and SIDS.
Hormones are transported through the blood stream to various organs and tissues. The male hormone is testosterone and the female hormone is oestrogen. Too much or too little of a particular hormone can lead to psychological problems for example too much dopamine can cause schizophrenia 1.b) Describe Selyes GAS Theory According to the biological approach hormones are responsible for regulating behaviours. Selyes General Adaptation syndrome (GAS) theory focuses on how the body respond to stress. Selyes research on rats led him to conclude that when exposed to stressful situations we display a universal response to all stressors regardless.

ECTOPIC PREGNANCY * An ectopic pregnancy, or eccysis, is a complication of pregnancy in which the embryo implants outside the uterine cavity. With rare exceptions, ectopic pregnancies are not viable. Furthermore, they are dangerous for the mother, since internal haemorrhage is a life threatening complication. * Most ectopic pregnancies occur in the Fallopian tube (called tubal pregnancies), but implantation can also occur in the cervix, ovaries, and abdomen. An ectopic pregnancy is a potential medical emergency, and, if not treated properly, can lead to death.
