Study Notes

Contraception and STIs

  • Contraception is the deliberate use of artificial methods or other techniques to prevent or stop a pregnancy
  • Contraception can be used before, during, or after sexual intercourse
  • Many contraception techniques are inspired by the causes of infertility
  • Three main types of contraception:
    • Hormonal
    • Barrier
    • Third
  • Barrier contraception creates a barrier that stops sperm from reaching the egg
  • Some commonly used barrier methods are condoms, spermicide, and female condoms
  • STIs are 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
  • Some STIs are not curable

Plant Reproduction

  • Angiosperms: The majority of plants use flowers to reproduce
  • Special features of a flowering plant:
    • Ability to asexually (self-pollination)
    • Ability to sexually (cross-pollination)
  • Asexual reproduction
    • Use both organs to fertilize themselves
    • Create a clone with the same characteristics
    • More exposed to viruses can adapt
