Ans. (b) Diagnosing chromosomal abnormalities in the foetus
Explanation:
Amniocentesis is a prenatal diagnostic procedure used to detect chromosomal abnormalities and foetal infections. It involves the extraction of a small amount of amniotic fluid, which contains foetal tissues, for analysis. This allows for the identification of conditions such as Down syndrome and other genetic disorders before birth.
Ans. (c) Amniocentesis
Explanation:
Amniocentesis is a diagnostic procedure used to detect chromosomal abnormalities and is not a method of contraception. In contrast, Vasectomy, intrauterine devices (IUDs), and oral contraceptive pills are all methods used to prevent pregnancy.
Explanation:
Sexually Transmitted Infections (STIs), formerly known as sexually transmitted diseases (STDs), are infections that are primarily spread through sexual contact. They can be caused by bacteria, viruses, or parasites. Common examples include HIV/AIDS, gonorrhoea, syphilis, and herpes. Many STIs can be asymptomatic, highlighting the importance of regular screening for sexually active individuals to ensure early detection and treatment.
Explanation:
Family planning is vital for reproductive health as it enables couples to determine the number and spacing of their children. This helps in avoiding unwanted pregnancies, reduces the risk of pregnancy-related health issues, and contributes to the betterment of the health and welfare of children. It also plays a significant role in controlling population growth and improving the socio-economic status of families.
Explanation:
Contraception is crucial for controlling population growth and maintaining reproductive health. Various methods of contraception include:
The importance of contraception lies in its role in allowing individuals and couples to decide if and when to have children. It helps in reducing unintended pregnancies, decreasing the need for unsafe abortions, and controlling the rate of population growth. Moreover, it contributes to the health and well-being of women by spacing births and reducing the risk of pregnancy-related complications. Contraception is also essential in preventing the transmission of STIs, especially barrier methods like condoms.
