Answer:
The correct answer is c) The first statement is true; the second is false.
Explanation:
To be able to perform its role, a hormone must bind a specific receptor in its target cell. The receptor can be located inside the cell (in cytosol) or in the surface of the cell (transmembrane receptor). By regulating the expression of the receptor, the target cell regulates the hormonal activity.
The number of hormone receptors in a cell is not constant, it can vary depending on sereral factors, such as the age of the organisms, the effect of several drugs, mutations or diseases.

Answer: Simple squamous epithelium
Explanation:
The simple squamous epithelium can be define as the layer of flat cells which can be found in contact with the basal lamina. This layer is permeable to allow the molecules to pass through the membrane for diffusion and filteration.
The diffusion of carbon dioxide and oxygen from the membrane of epithelia is also facilitated by the simple squamous epithelium.
To put it simply these cells are technically termed as Eukaryotic (multi-celled) and Prokaryotic (single-celled) cells.
There are differences between Eukaryotic and Prokaryotic cells. This difference is considered to be the most important distinction between groups of organisms. A Prokaryotic cell does not contain a nucleus. It only contains one chromosome and is a single-celled organism. It was the only form of life on earth for millions of years. Examples of a Prokaryotic cell are the different types of bacteria present today.
A Eukaryotic cell contains a nucleus; more than one chromosome and is typically a multi-celled organism. Both plant and animal cells are eukaryotic cells.
<span>The advantage is that eukaryotic cells have a nucleus which functions formally as to store the DNA of the cell which can translate into many functions such as cell division and work structure between cells that forms the hierarchial function to tissues.<span>
