How would you distinguish pseudostratified columnar epithelium from all other tissues?.
inn [45]

Psuedo  functions mostly absorption and filteration processes.

<h3>What is the advantage of psuedostratified epithelium? </h3>

The lungs are shielded from these irritants by the existence of pseudostratified columnar epithelium in the upper respiratory tract, which is made up of the nose, trachea, and bronchi. To capture particles and stop them from moving farther down the respiratory passages, the epithelium's goblet cells release mucus.

The psuedostratified has too many layers and it is made up of columnar epithelial tissue.

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.

How does facilitated transport (facilitated diffusion) help a cell maintain homeostasis?
7nadin3 [17]
Diffusion is when particles move from an area of high concentration to an area of low concentration. Think of it like a little kid party with two bouncy houses. Let's say that both bouncy houses have the same number of kids, but then half of the people in one bouncy house decide to go get lunch. Then one bouncy house is really full and the other almost empty! So you move to the empty bouncy house so you have more space to jump. This is diffusion. So it helps homeostasis because (back to the bouncy house example) you helped even out the two bouncy houses. Now let's say the kids come back from lunch. Now that bouncy house is too crowded so you move back to the now-emptier one. This is diffusion and you would be helping maintain homeostasis, or an equal level, in both bouncy houses.
