Answer:
This element is carbon.
Explanation:
You might be quick to think the answer is something like hydrogen and oxygen because both form to make water. But understand that the question is not asking about important elements in life, just which element makes up organic molecules. This element happens to be carbon.
It's important to understand that carbon is lucky in that it has 4 valence electrons and is able to bond with other important elements, like F, N, and especially H. The bond between C-H is essential in organic chemistry because it represents the structure of an organic molecule and helps with the IUPAC naming of organic molecules. It also suffices to say that there is a cycle for carbon in the carbon cycle, which transports carbon from one place in our world to the other.
So, it suffices to say that carbon is in fact essential for making up organic molecules.
Answer:
The correct answer is: a basement membrane.
Explanation:
The basement membrane is a thin and fibrous membrane that is found under the epithelium and<u> attaches it to the connective tissue</u>. The basement membrane is <u>composed of two membranes</u>: the basal lamina (with laminin and collagen IV, among other proteins), and the lamina reticularis (that has collagen III making up reticular fibers). The basement membrane also has the function of a <u>mechanical barrier that prevents the invasion of deeper tissues by malignant cells</u>.
Epithelial tissue and connective tissue are two of the four basic tissues found in the body (the other two are nervous tissue and muscle tissue). Epithelial tissue makes up the skin and the <u>inner lining of hollow organs</u> (like the stomach or the trachea), and has multiple functions that are responsible for the function of the organ where it's located. Connective tissue is basically any type of tissue that connects the epithelium to muscle tissue or nervous tissue: <u>from blood, to bone, and to fat</u>.
