Study Notes

Contraception and STIs

Contraception is the deliberate use of artificial methods or other techniques to prevent or stop pregnancy.
Many methods can be used before or after sexual intercourse.
Methods are inspired by the causes of infertility.
The three main types of Contraception are hormonal, barrier, and third.
Hormonal methods change the environment to be unfavourable.
Barrier methods prevent sperm from reaching the egg.
Third methods create environments that are not favorable to sperm and eggs.
STIs stand for sexually transmitted diseases.
STIs are caused by bacteria, viruses, or parasites.
STIs are transmitted through sexual contact, including vaginal, anal, and oral sex.
Some STIs are curable, but some aren't.
Examples of incurable STIs include syphilis, gonorrhea, herpes simplex, chlamydia, and trichomoniasis.
Examples of curable STIs include hepatitis B.
HIV and HPV are not curable.
Symptoms of STIs can be managed, some can be deadly.
STIs can affect fertility.

Plant Reproduction

Angiosperms are the majority of plants.
They use flowers in the reproduction process.
Special features of flowering plants include;
- Ability to reproduce asexually (self-pollination)
- Ability to reproduce sexually (cross-pollination)
Asexual reproduction:
- Use both organs to fertilize themselves
- Creates a clone with the same characteristics
- More exposed to viruses can adapt
