Veronica wrote charles darwin’s main points on the board, but she made a mistake in one point.
1. since more offspring are produced than an environment can support, organisms within a population must compete for resources to survive.
2. due to variations within the population, some competitors will be better equipped for survival than others.
3. the best-equipped organisms will survive and will produce well-equipped offspring.
4. variations that with survival will be passed on to future generations and will rapidly change the whole population. which point is flawed as written above?
point 1
point 2
point 3
point 4

the answer is 4  so its the last option

i'm pretty sure it's spores

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.
