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.
Answer:

Answer:
B, C, D, A
Explanation:
because i got it right on one of my tests
The ventral visual stream projects to the inferior temporal cortex and is involved in the perception of form. While the dorsal visual stream projects to the parietal association cortex and is involved in the analysis of spatial location. the ventral visual stream is a pathway that stretches from the primary visual cortex in the occipital lobe forward into the parietal lobe.
The answer is true hope it helps
