<span>All cells have the same DNA. They are different because different genes have been locked up and only some of them are expressed. The process began in the embryonic stage, when stem cells are turned into different types of cells by turning off some of the genes. Scientists have been looking for ways to reverse the process, meaning turning specialized cells back into stem cells. Some success has been reported using different methods. The latest one uses a weak acid to stress the cells.</span>

Describe a characteristic of both an Emperor Penguin and Galapagos Penguin that evolved differently due to their different envir
nevsk [136]

Answer: The size.

Explanation: On the one hand the Emperor Penguin is bigger reaching up to 48 Inches (120cm) of height and 100 Lb in weight, on the other hand the Galápagos Penguin is much smaller. For example a large adult usually goes up to 21 Inches (53cm) and 5 Lb of weight.

This is directly related to the temperature of the environment in which each one develops, because a body exchanges heat in two dimensions through the surface. So, it's easier for a big creature to maintain core temperature stable.

This is really important in environments like the Arctic where temperature goes below zero and the opposite happen in the Equator where there is a tropical weather all the time.
