Answer;
-Inactivation; limited
Differentiation requires inactivation of particular genes to produce populations with limited capabilities that form tissues.
Explanation;
-Cell differentiation is how generic embryonic cells become specialized cells. This occurs through a process called gene expression.
-Gene expression is the specific combination of genes that are turned on or off (expressed or repressed), and this is what dictates how a cell functions.
-Gene expression plays a critical role in the morphological changes that take place in a developing embryo and fetus and in the differentiation of stem cells to form specialized cells.
<span>Amoebas are able to protect themselves from unfavorable conditions by forming a "cyst." An amoeba is type of organism that has the ability to change its shape. The reason for this is for the reason of extending and retracting pseudopods.</span>
Darwin believed in evolution through natural selection; organisms that were the most well adapted to their environment would pass on their genes to their offspring (which the organism would have inherited at conception).
Lamarck on the other hand believed that organisms passed on traits that they had acquired during their lifespan to their offspring.
We know now that Darwin was correct, and that Lamarck was wrong.
