Choose the incorrect statement(s):
select one or more:
a. proprioception is an example of a special sense
b. the skin contains receptors for touch, pressure, and proprioception
c. taste buds are groupings of cells found in the tongue epithelium.
d. receptors can be classified into 6 types
e. all of the above statements are incorrect

option D

Receptors are not classified into 6

Explanation:

Receptors are protein molecules in the cell or cell surface that binds ligands.

Receptors are classified into two, which are;

1.Intracellular or cytoplasmic receptors which are found in the cytoplasm of the cell and the give response to hydrophobic ligand molecules that move across the cell membrane.

2. Cell surface receptors or transmembrane receptors, the are found in the cell surface or cell membrane and they bind to the external ligands molecules.

when atoms of different types of elements join together, they make molecules called compounds. water consists of compound molecules made up of 2 hydrogen atoms and 1 oxygen atom. this is why it's called h2o. water will always have 2 times the number of hydrogen atoms as oxygen atoms.

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.
