Cancerous growths are clonal in origin because of cancer cells originate from a single cell that has accumulated genetic changes during cell division.

The human body contains several billion cells. Cells are the teeny, tiny building blocks of our tissues and organs. Every one of us was once a single cell. That cell divided into two new cells after internal replication.

Cells become abnormal when the DNA, which holds the instructions needed for cells to operate, is damaged. The cells they make after that will not be similar to healthy ones. Along with having a variety of appearances, they might also possess different traits. The medical word for this kind of abnormal cell proliferation in body tissue, including skin, is dysplasia. As long as there aren't many abnormal cells and our immune system controls them, we won't get sick from them.

Sometimes these cells can vanish on their own. Only when these cells continue to change and start to divide erratically, leading to lumps or growths, does one of the more than 200 diseases recognized as cancer become apparent. These kinds of growths are tumors.

The complete question is:

Cancerous growths are clonal in origin because of cancer cells __________.

(A). can invade healthy tissues originating from a single cell that has accumulated genetic changes during cell division

(B) can migrate to other areas of the body and form secondary tumors at the new sites

Answer:

<h2>Through production of news cell-surface proteins with a different molecular structure by each new generation. Letter B</h2>

Explanation:

The life cycle of theses paratises extracellular alternate between the salivary glands of the insect transmitter and the blood of the mammal. During the set prior to the entry into the host, the metacylic parasites express a dense over formed by the Variant Surface of Glycoprotein, after entering to the mammal host they transform into a morphology that stays in the bloodstream.

<em>The parasites have to manipulate hosts cells in order to avoid the production of antimicrobial molecules and to benefit from growth factor production.</em>

<em>Intracellular protozoa have a remarkable adaptive capacity as they are able to resist killing by remodelling the phagosomal compartments where they reside and by interfering with the signalling pathway that leads to cellular activation. </em>

irina1246 [14]

Answer:

false

Explanation:

Although the majority of the air we breathe is N2, most of the nitrogen in the atmosphere is unavailable for use by organisms. This is because the strong triple bond between the N atoms in N2 molecules makes it relatively unreactive. However organisms need reactive nitrogen to be able to incorporate it into cells.
