I SHALL GIVE YOU BRAINLIEST! (1) What are the four cell types in Trichoplax adhaerens? Explain their locations within the animal.

(2) What is the purpose of the os culum in sponges?
Select one:
a. It is the egg cell of sponges.
b. It is a tiny pore through which water containing food enters the sponge.
c. It is a large opening through which the water containing waste exits the sponge.
d. It is the gel-like substance that all the sponge cells are suspended in.

Wanna be friends? :) I've got dis and ro blox! :)

Trichoplax contains at least six somatic cell types: dorsal and ventral epithelial cells, lipophils, fiber cells, gland cells and crystal cells. Placozoans can move in two ways, by gliding on their cilia and by changing their shape like an amoeba. ... Placozoans can reproduce asexually by either binary fission or, less often, by budding. Some laboratory observations suggest that sexual reproduction may occur. The amoebocyte assists in the digestive process and in the distribution of nutrients to other cells of the body. Amoebocytes are also totipotent, meaning that they can change into other sponge cell types. In some species, amoebocytes are able to become egg or sperm cells for sexual reproduction

Explanation:

it has to be understood that the sea water contains a huge amount of sodium and chlorine ions and if they enter the cell of the atlantic cod fish, the cell will shrivel and the fish will die. to avoid such a condition, the fish uses active transport for the purpose of removing the ions against the gradient.

explanation:

the atlantic cod is not a maritime osmoconformer. its native application of salts is less than that of the seawater it lives in. it is continually falling water from the gills to the ocean via osmosis.

countering that, the fish is going to be swallowing seawater. but since its internal collection of salts is lower than seawater, the fish will want to go free of excess salt, and since that's going upon a gradient, then active transport, requiring energy, must be used to pump out the salt. much marine fish use the organs to filter out the salt and these fish discharge very straight urine.
