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?
The plant is a gymnosperm, and the gametophyte is its dominant phase.
The plant is an angiosperm, and the gametophyte is its dominant phase
The plant is a moss, and the sporophyte is its dominant phase.
The plant is a fer, and sporophyte is its dominant phase.

explanation:

the fossil record extends back to a dog-like ancestor some 55 million years ago, which gave rise to the first horse-like species 55 to 42 million years ago in the genus eohippus.

regents of the university of california v. bakke, 438 u.s. 265 (1978), was a landmark decision by the supreme court of the united states. it upheld affirmative action, allowing race to be one of several factors in college admission policy.

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.
