There are many routes in introducing drugs into the body. Hypodermic injection per se, is introduction of drugs into a part, as into subcutaneous tissues, the vascular tree, or an organ. the prefix hypo means "under" while the latin word derma refers to the "skin". Transdermal administration on the other hand, is the route wherein active ingredients are delivered through dermis or skin only. One example is the transdermal patches. 
Thus, hypodermic needle administration is not called transdermal, it is rather called subcutaneous administration.

are comprised of an ester of a long-chain alcohol and a fatty acid. Many plants have leaves and fruits with wax coatings to help prevent water loss.

Phospholipids

THe phosphate portion is soluble in water [hydrophobic] forms the ''head'' of the molecule, while the fatty acids portion is insoluble in water [hydrophobic] and forms a ''tail''.

with reference to the role of oncogenes, explain how the normal controls over the cell cycle can be lost.
Katena32 [7]
<span>#1) With reference to the role of oncogenes, explain how the normal controls over the cell cycle can be lost.

Answer: The way that cell cycle can be lost is by going through changes in the activity of cell cycle regulators. Cancer causes different types of mutations. There are two types of cell cycle regulators that can promote the development of cancer:

-Positive Regulators that can be over activated (become oncogenic).
-Negative Regulators (tumor suppressors) which can be inactivated.
