Write a paragraph explaining the function of a cell wall and cell membrane and why plants have cell walls and animal cells do no
butalik [34]

A cell wall is a structural layer surrounding some types of cells, just outside the cell membrane. It can be tough, flexible, and sometimes rigid. It provides the cell with both structural support and protection, and also acts as a filtering mechanism.[1] Cell walls are present in most prokaryotes (except mollicute bacteria), in algae, fungi and eukaryotes including plants but are absent in animals. A major function is to act as pressure vessels, preventing over-expansion of the cell when water enters.

How is the chemical compositon of hydrothermal vents fluid different from surrounding sea water
ICE Princess25 [194]
HEY THERE!!

When seawater seeps down into the ocean crust and is heated by the magma, it undergoes lots of chemical reactions. When the fluid rises up through the seafloor, it carries many new chemicals with it, such as-- copper and zinc.
These chemical reactions also remove chemicals from the seawater, such as oxygen and magnesium.

So clearly vebtus fluid is different from sea water .

Why is a soil profile in a tropical rain forest different from one in a desert?
Kaylis [27]
Well, in a tropical rainforest, there is more opportunities of the area getting moisture, in this case, rain, rather than a desert. In a desert, it can't hold moisture because of its arid days and gelid nights. Because of the sun drying up every inch of moisture it receives, the desert simply cannot hold any type of human or plant life.

I hope I helped :)
