Daphnia is a small water invertebrate that is almost transparent. like all animals, daphnia require chemical energy to live. it uses structures called gills to extract oxygen from the water to it obtain chemical energy. which statement below describes how they obtain chemical energy?

Daphnia - Water invertebrate

Daphnia obtain chemical energy by absorbing blucose from algae. Then it is used in cellular respiration to produce nicotinamide adenine dinucleotide(NADP) which is chemical energy. Daphnia require chemical energy in the form of NADP. So, it uses gills to extract oxygen from water (H2O) to help it obtain chemical energy.      

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 going to be a because ik that i’m right
