Julio is studying the evolutionary history of desert cottontail rabbits, sea otters, and grizzly bears. All three species share
krek1111 [17]

Answer:

One way that Julio can explain such differences is that their environments are very similar and therefore the traits that were best suited for their survival were passed on from generation to generation. The traits that each species developed differently would have been due to their diet. Each species has a different diet and certain traits allow them to more easily hunt/gather the food that they need to survive. For example, grizzly bears and sea otters both eat fish as their main diet and therefore have both developed canine teeth, while rabbit teeth are different due to them only eating vegetation.

Virtually all cells in the human body have the same DNA. What’s make some undifferentiated cells differentiated into brain cells
mariarad [96]

Answer:

Changes in gene expression

Explanation:

This phenomenon is the result of changes in gene expression. That means, how the information in the DNA is used by the cell. The genes that are active in the cells of the brain will be very different from the genes that are active in the cells of the bone marrow.

These patterns of gene expression are different for each cell, and dictate the identity of that cell. Gene expression patterns are controlled by a variety of factors in the cell that allow tissue-specific expression, such a transcription factors.

This can also be facilitated by another layer of regulation called epigenetics, which literally means "on top of" genetics, and refers to modifications of DNA (and the proteins around it), that can reflect and influence the activity of the genes within.
