Jenner's successful use of cowpox virus as a vaccine against the smallpox virus was due to the fact that ______. (A) the cowpox
virus made antibodies in response to the presence of smallpox(B) the immune system responds nonspecifically to antigens(C) cowpox and smallpox are caused by the same virus(D) there are some epitopes (antigenic determinants) common to both pox viruses
Answer: option C) cowpox and smallpox are caused by the same virus
Explanation:
Cowpox is a skin disease that affects cattle. It is caused by an Orthopoxvirus, with lesions occurring principally on the udder and teats of the animals.
Human infection may occur from touching infected cows, and thus giving immunity to smallpox (an acute infection caused by the same poxyvirus, in HUMANS)
So, Jenner's successful use was because cowpox and smallpox are caused by the same virus
The hyaline cartilage is the most common cartilage in the
body. It is a glass-like, translucent , bluish-white cartilage that can be
found on many joint surfaces, the respiratory tract and immature skeleton. It
is also present in the ribs, nose, larynx and trachea.
The submarine will most likely find data that shows the highest pressure data and the lowest temperature data (unless of course it's near a hydrothermal vent). This is because due to the depth there's a lot more water above it putting a lot of pressure on the sub, and very little sunlight to heat up the water.
