Which term is used to prevent a disease?
Correct Answer
D. Vaccine
Explanation
A vaccine is a substance that is used to prevent a disease by stimulating the immune system to produce antibodies or other immune responses. It contains weakened or killed microorganisms or parts of microorganisms that mimic the disease-causing agent. When the vaccine is administered, the immune system recognizes these antigens and mounts a response, creating memory cells that can quickly respond to the actual disease-causing agent in the future. Therefore, a vaccine is used to prevent a disease rather than treat it.

In which part of the reproductive tract of a female is it recommended to deposit semen when using artificial insemination?
Correct Answer
D. Uterus
Explanation
When using artificial insemination, it is recommended to deposit semen in the uterus. The uterus is the part of the reproductive tract where fertilization and implantation of the fertilized egg occur.

The vulva is the external opening of the reproductive tract, the vagina is the canal leading to the cervix, and the cervix is the narrow passage between the vagina and the uterus. While sperm can pass through these parts, depositing semen directly into the uterus provides a more efficient and direct route for fertilization.

What does a cow's colostrum contain that makes it essential to the newborn calf's developing immune system?
Correct Answer
B. Antibodies
Explanation
A cow's colostrum contains antibodies that are essential for the newborn calf's developing immune system. Antibodies are proteins produced by the immune system to help fight off infections and diseases. When the calf consumes colostrum, it receives a passive transfer of these antibodies, which provide immediate protection against pathogens until its own immune system develops. This is crucial for the calf's survival and overall health, as it helps prevent infections and boosts its immune response.
