Steel is denser than plastic, yet sound travels faster in steel than in plastic. develop a hypothesis to explain why. in hypothesis, you will write a because statement afterwards. this because statement should explain why sound travels faster in steel even though it is denser than plastic.

Sound travels faster in higher density objects than lower density objects.

Steel is a huge conductance for example with electricity

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.

Ibelieve its b but u might have to
