As esponjas possuem em seu revestimento interno células denominadas de coanócitos. Qual é a forma e as funçoes dessas células para a esponja?

The sponge uses this structure for  feeding. It is located in whip-like appendages (the flagella)located in the sponge.It generate water currents as the flagella beat the water current , and as food particles passes through  with the water current , it(choanocytes) trap these, and ingested it by in folding of its inner membranes .a process called phagocytosis.

Explanation:

the oceanic zone is typically defined as the area of the ocean lying beyond the continental shelf, but operationally is often referred to as beginning where the water depths drop to below 100 meters (328 feet), seaward from the coast to the open ocean.

explanation:

tsd is temerature dependent sex determination.

tsd: it is a type of environmental sex determination in which the temperature experienced during embryonic/ larval development (ambient temperature for development) determine the sex of the offspring.

crocodile displays the tsd where the ambient temperature of the developing egg determines the individual's sex. for example in the american alligator's eggs, incubation at 33 ºc produces mostly males, while incubation at 30 ºc produces mostly females. so if the american alligator's egg will get the ambient temperature (33 degree celcius)during embryonic development from egg, the offspring will be male and same for the female sex determination.
