Answer:
Sometimes ovaries release extra eggs.
Explanation:
Birth control or the pill is a pill that's taken on a daily basis and it contains hormones (estrogen and progesterone), in order to change the way the body works and prevent unwanted pregnancies. In this case, the pill controls ovaries and uterus. Most of the pills are mixed pills and work in order to prevent ovulation ( releasing egg during monthly circle ). While on the pill, a woman can't ovulate because there is no egg to be fertilized. It also thickens the mucus around the cervix and makes it difficult for sperm to get to the uterus and <em>reach any extra eggs that may have been released</em>. The hormones in the pill sometimes also affect the lining of the uterus and make it hard for <em>an egg to get attached to the wall of the uterus.</em>

Answer:
D. decreasing p or increasing B.
Explanation:
From the formula presented for the sake of answering this question as shown below:
n = Np (1-p)/
(N-1)B squared/4 + (p) (1-p)
Hence, the number of subjects can be reduced while having the least impact of the study reliability if we decrease the proportion of subjects needed (p) or increase the acceptable amount of error (B). This way, the study still remains reliable.
Answer:
Transport the patient by ambulance, monitor closely and administer fluids en route.
Explanation:
The rate of a normal resting heartbeat is 60 to 100 per minute. The atria (the two smaller chambers of the heart) contract simultaneously and so does the ventricles (the two largest chambers). This mechanism causes the “double beat” characteristic of the heart: tummy, tummy… Exercise, emotional stress and even stimulating drugs can increase the heart rate to 200 or more beats and cause the heart to beat too fast. When this happens we call it tachycardia.
In the case of the man shown in the question, tachycardia occurs because of the ingestion of caffeinated soda. Although tachycardia is normal for those who use this type of substance, if the heart beats too fast it can lead to congestive heart failure and even myocardial infarction. For this reason, the ideal thing to do for this man is to transport him in an ambulance, closely monitor him and administer fluids on the way, as fluids can adjust the heart rate.
