<span>Epithelial tissue is densely packed cells that used most in the area where protection is needed. This cells mostly used in skin, some with more keratin which will increase their ability to protect. In bone, the main protective layer is calcium mineral which was deposited by osteocytes. Because this bone doesn't really need more epithelial cells. Bone tissue only needs a good vascularization and connective tissue to support it.

A type of commensalism is the sea anemone and the clown fish. The definition of commensalism is where another species lives within another. (Usually this relationship is with animals, fungi, and plants.) No harm comes to either species.
A clown fish lives in a sea anemone, and this doesn't hurt the anemone nor is the clownfish affected by its sting because of their oils that protect them.
If you didn't know, Nemo and his father, Marlin, lives in a sea anemone. A natural habitat of a clown fish.
Yes, this is correct!
Let's imagine two systems, one with 50 species and one with 4000. Both of them experience a draught and as a result 25 species of the first one die (that's quite likely) and 800 of the second population die out (more would not be very likely).
So the first one lost 50% of species and the second one 20% - that means that the second one, with greater biodiversity has a bigger stability:)
the excretory system. the kidney produce more concentrated urine so less water is lost from the body. sweat help maintain your body's natural temperature.
