Pluripotency
Differentiation
A model of pluripotent vs differentiated cellular gene expression is shown. Pluipotency is found in stem cells that
have the ability to become multiple types of cells. Differentiation is the process where a cell becomes specialized
and cannot return to its pluripotent state. What explanation best supports the model of pluripotency and
differentiation shown above?
Differentiated cells have different DNA sequences that
pluripotent cells and can produce different protein products.
Differentiated cells have fewer gene sequences that pluripotent
cells and can only produce limited numbers of proteins.
Pluripotent cells recruit molecules from nearby cells to increase
gene expression while differentiated cells use only internal
transcription factors.
Differentiated cells and pluripotent cells have different types of
activator or repressor proteins present that positively and
negatively regulate gene expression in the cell.

colors do exist. the color of the sky is actually violet; humans percieve the color of the sky as blue.

the two answers are a, the population of birds with large beaks will increase on the island, and c, the trait for large beaks will be passed on to future generations through natural selection. the reason for that is because if the birds that have beaks developed for eating small seeds lose all of their food, they will go hungry and eventually starve because they physically cannot eat the large seeds, therefore making the population of large beaked birds higher. also, if the trait of large beaks are dominant on the island over small beaks, then over time the large beaked birds will reproduce more and more, while the smaller beaked birds will reproduce less and less because they can't survive with the food provided. that leads to the trait of small beaks disappearing and the trait of large beaks taking over the island.

yes, because even though a theory has a  lot of evidence to support it, it is not always true
