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.

The smallest fragments of DNA will be witnessed near the bottom of the gel, on the other hand, the heavier fragments will be visible at the top. The theory behind this is there is a specific pore size on the basis of the concentration of acrylamide/agarose in the gel.
The nasal cavity is the hollow pipe (your nostril and upwards) that is covered with hairs and muscus membrane. Its main functions are to warm, moisturise, and filter air before it entering the body.

In comparison to eukaryotes, prokaryotes are smaller. Eukaryotes and prokaryotes<span> are type of cells. The prokaryotes </span><span> contain no membrane-bound organelle such as</span><span> nucleus and are found in the domains of Bacteria and Archaea. E</span>ukaryotes contain a nucleus and make up the remaining domain. Prokaryotes tend to be much smaller in size than eukaryotic cells.
