Ellen began forgetting where she put her purse, how to balance a checkbook, and where she left the car in the parking lot. She is experiencing the signs and symptoms of:
Alzheimer's disease.
menopause.
menarche.
old age.

Alzheimer's disease

Explanation:

Alzheimer's disease occurs when there is a presence of abnormally structured  neurons and a reduced amount of acetylcholine in the regions of the brain involved in reason and memory. These neurons have fibrous proteins present in the form of bundles around the nucleus and amyloid plaques. Malfunctioning of these regions of the brain results in a gradual loss of reason with memory lapses. It makes the person unable to perform any type of daily activity. The given symptoms represent the fact that she is suffering from Alzheimer's disease

gold i'm pretty sure i might be wrong

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.
