Which of the following best describes a characteristic that distinguishes animals from protists?

a) most animals are eukaryotes, and most protists are prokaryotes.

b) most animals have bilateral symmetry, and most protists have radial symmetry.

c) most animals have cell walls containing proteins, and most protist cell walls contain chitin.

d) most animals are multicellular, and most protists are unicellular.

the sporophyte of an unknown plant species grows as a separate plant than the gametophyte. the plant produces both female and flagellated male gametes from the same gametophyte, and it releases spores into the environment. which of the following is the best conclusion about the life cycle of this plant?

a) the plant is a gymnosperm, and the gametophyte is its dominant phase.

b) the plant is an angiosperm, and the gametophyte is its dominant phase.

c) the plant is a moss, and the sporophyte is its dominant phase.

d) the plant is a fern, and sporophyte is its dominant phase.

D) Most animals are multicellular, and most protists are unicellular.

Don't worry, I just took the test and paid attention in class.

(Further explanation linked below 'cause is mean and wouldn't let me just write it. Brainliest would be appriciated.)

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.
