Why is it difficult to bond three phosphate groups to Adenosine? They have the same charge and repel each other.

They form a strong attraction to each other.

They are like opposite poles of a magnet.

The energy is evenly dispersed across all three bonds.

I think that answer is they are like Opposite poles of magnet.

I really hope it’s right

The answer is observations and interpreting.

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.
