<u>Answer:</u>
Cancer cells attached to organs.
<u>Explanation:</u>
The cells which have lost their ability to divide in a controlled manner are categorized as cancer cells.
Cancer cells undergo the process of cell division uncontrollably without stopping which results in the development of cancerous tissues within the body.
Moreover, these cells can form in any of the organs of the body to which several reasons are associated for being responsible for the formation of these cells.

Madeira and Canary islands and made a landfall at the Cape of Verde islands. The
expedition was originally planned to end in two years. It got delayed and
turned into five years due to Darwin spending most of his time exploring on
land. the answer is D.</span>
The phospholipid bilayer has two hydrophilic surfaces: the extracellular and the intracellular surfaces. These two layers sandwiches a major layer of lipids or fat. Because of this nature of the lipid bilayer, water-soluble or <em>hydrophilic</em> hormones cannot enter the cell membrane. They have to rely on the mechanisms of receptors.
One can find transmembrane proteins embedded across the whole length of the lipid bilayer. One of the functions of these proteins is to serve as the link for hormones such as the ones given above. When the water-soluble hormones attach to one of these receptors, the receptor will be activated and send down a signal to the intracellular environment; these signals will then travel down towards their target site and eventually activate whatever it is the hormone was made for. One example of these transmembrane proteins are <em>G-coupled proteins; </em>examples of signals that cascade down the cell are cylic AMP and cyclic GMP.
