WILL GIVE BRAINLIEST!! Which of the following best describes the changes that take place in an ecosystem during primary succession?

A. Lichens and mosses grow slowly on newly formed land, followed by grasses, shrubs, and trees.
B. Shrubs and trees regrow quickly in areas that have been disturbed by a forest fire.
C. Organisms compete for resources, and those that are best fit to survive establish themselves as the dominant species.
D. Natural disasters cause many populations to migrate to a new location in order to survive.

the diploid number of chromosomes is sometimes represented by the symbol 2n. for the fruit fly, the diploid number is 8, which can be written as 2n = 8, where n represents twice the number of chromosomes in a sperm or egg cell.

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.

it's diluted or concentrated

in a diluted solution, you can add a lot more solute but in concentrated only a little more can be added
