The answer is D. nuclear membranes
Prokaryotic cells don't have nuclear membranes and Eukaryotic cells do
Answer :
Vinegar is a weak acid. This is used to make a naked egg. When an egg is added in the vinegar for one day / 24 hrs, it reacts with the eggshell. The calcium carbonate shell gets dissolve.
Then an egg without shell is formed and the size of the egg does not change. The calcium carbonate reacts with acetic acid and forms carbon dioxide.
When the shell-less egg is kept in the vinegar for 48 hrs i.e. 2 days again, the water content in it enters into the eggs through the membrane. Then the egg gets somewhat bigger.
Otherwise, for 24 hrs, vinegar is acting like an isotonic solution and only dissolves the shell. This experiment would be done for showing the osmosis process through the cell membrane.
The hormone <u>adrenocorticotropin hormone</u> (ACTH). which is secreted by the adrenal cortex, causes the kidney to conserve <u>sodium</u> ions and excrete <u>potassium</u> ions and indirectly helps to maintain systemic blood pressure.
<h3>What are hormones?</h3>
Hormones are chemical messangers or substances which are produced by the body and released to the sites where they are needed in the body
So therefore, the hormone adrenocorticotropin hormone (ACTH). which is secreted by the adrenal cortex, causes the kidney to conserve sodium ions and excrete potassium ions and indirectly helps to maintain systemic blood pressure
