Answer:
Eukaryotic and Prokaryotic cells are fundamentally different.
Explanation:
A prokaryotic cell is basically an entire organism that works within a single cell. Its genetic material is not in a nucleus.
A eukaryotic cell is part of an organism. This cell has its genetic material in the nucleus. In addition, it possesses organelles.
All cells are not the same because some, like the prokaryotic ones, make up an entire living organism. Others, like the eukaryotic cells, are part of much more complex living forms. Furthermore, each cell type within each category has unique functions.
An efficiency apartment can be compared to a prokariote. Prokariotes have everything they need in one cell. A mansion is more similar to a eukaryote. Every room of the mansion is important for the fully equipped mansion.
Answer;
Cycilc AMP
Explanation;
-Second messengers are molecules that relay signals received at receptors on the cell surface; such as the arrival of protein hormones, growth factors, etc., to target molecules in the cytosol and/or nucleus.
-Many of the chemical messengers such as hormones, that transmit messages from one cell to another never enter the target cell, these molecules are known as first messengers which work by binding to a specific receptor on the cell surface. The receptor then stimulates or inhibits the production of a so-called second messenger within the cell.
-The second messenger are small molecules such as Cyclic AMP, which activate an effector within a cell.
