Hydras may reproduce by budding. In this process, a small polyp forms on an adult hydra, and then it leaves to become a new organism. Which observation
would support the conclusion that budding is an example of asexual
reproduction?
a. The polyp that buds off the hydra has different DNA from the parent.
b. The polyp that buds off the hydra is significantly smaller than its parent.
c. Budding may occur in a hydra that has been completely isolated from others
of its kind,
d. Budding may occur in a hydra that has been raised with many others of its
kind

answer: - b cells

explanation: -

there are many types of white blood cells present in our body. one such class of white blood cells are the lymphocytes. the b cells belong to the lymphocyte class of wbcs. the b cells perform their action against the pathogen by producing specialised proteins called as antibodies. these antibodies are produced as and when the b cells encounter pathogens in response to the antigens present on the surface of the pathogen. these antibodies bind to the antigens present on the pathogen and then, target them for destruction by other cells of the immune system.

so, the b cells mediate their action by identifying the antigens present on the surface of the pathogens and then producing antibodies in return to mediate its effect.

The answer is nucleic acid
