Based on these two observations, would you say that a cell spends most of its life cycle in interphase or in mitosis/cytokinesis?

A cell spends most of its life cycle in interphase

Explanation:

Cells generally spend most of their life cycles in the interphase phase.

A typical life cycle of a cell is divided into two main phases, which are;

The interphase represents a period between the last stage of one mitotic division and the beginning of another one while the m phase represents the mitosis itself. Typically, the interphase takes up about 91% of the entire cell cycle while the remaining part of the cycle, the active division/mitotic phase takes up the rest.

affects the water bodies: excessive use of fertilizers causes eutrophication. the fertilizers which are used on plants affect the quality of land on which it is used, further causing erosion of soil. the fertilizers used on plants contain harmful chemical fumes which affect the environment.

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.
