It can be frozen (32°F or 0°C) which would slow the energy of the molecules. or it could be boiled (212°F or 100°C) which would rapidly increase the speed of the molecules.
they are both structural and geometric isomers
The correct answer is <em>epithelial tissue.
</em>
There are different types of epithelial tissue depending on the type of cells its made of: squamous, columnar, and cuboidal. It can also be divided into simple and stratified depending on the number of layers. Functions of epithelial cells are wide such as secretion, absorption, protection..
All what the word tetravalent means is that carbon can form 4 chemical bonds, due to the fact that carbon has 4 unpaired valence electrons in its furthest shell, which can be used to bond to other atoms, to form linear and cyclic structures in organic compounds.
Tetravalent also tells us indirectly what the molecular geometry of the atom would be if bonded to those number of bonds, if 4, then it would be tetrahedral and have bond angles of 109.5.
