1. How, in general, do contraceptives work? What is the difference between perfect-use and typical-use failure rates? Which do you think is a better predictor of effectiveness? Why?

Answers

Answer:

Explanation:

1 Hormonal birth control methods prevent the ovaries from releasing eggs, thicken the mucus of the cervix to prevent sperm from entering the uterus, and thin the lining of the uterus to prevent implantation.

2 Typical use means how well the method works to prevent pregnancy when people use it in real life, while perfect use means how well the method works when it is being tested in a clinical trial. by people who are following the instructions to the letter always and for a full year. For example, a perfect use effectiveness rate of 99% means that over the course of a year, on average, 1 out of 100 people who used this method as directed will get pregnant.

Since life is not a clinical trial, we recommend that more attention be paid to numbers that reflect typical use of the method. But you can get closer to the perfect number if you learn to use the method correctly and consistently.

Some methods, such as the IUD and the implant, have a typical use rate very similar to the perfect use rate. This is because in these methods there is very little room for error because the person does not have to do or remember anything, they just have to change it from time to time. Other methods, such as condoms, have a more drastic difference between typical and perfect use rates, because there is more opportunity to make a mistake when using these contraceptive methods.

3 Blood pregnancy tests are about 99% accurate. The blood test is often used to confirm the results of a home pregnancy test.

The HACCP system can be applied at all points throughout the food supply chain, from food preparation and production to packaging and distribution.

Answer:

The digestive system is made up of the gastrointestinal tract—also called the GI tract or digestive tract—and the liver, pancreas, and gallbladder. The GI tract is a series of hollow organs joined in a long, twisting tube from the mouth to the anus. The hollow organs that make up the GI tract are the mouth, esophagus, stomach, small intestine, large intestine, and anus. The liver, pancreas, and gallbladder are the solid organs of the digestive system.

The small intestine has three parts. The first part is called the duodenum. The jejunum is in the middle and the ileum is at the end. The large intestine includes the appendix, cecum, colon, and rectum. The appendix is a finger-shaped pouch attached to the cecum. The cecum is the first part of the large intestine. The colon is next. The rectum is the end of the large intestine.

Bacteria in your GI tract, also called gut flora or microbiome, help with digestion. Parts of your nervous and circulatory NIH external link systems also help. Working together, nerves, hormones, bacteria, blood, and the organs of your digestive system digest the foods and liquids you eat or drink each day.

In other cases, working parents do not want to move their children away from good schools even though, sometimes, their jobs are far away.
