The ozone layer keeps harmful rays from the sun also the atmosphere burns up small deburey from rockets, space trash ex. Also small rocks and particles can get burned before hitting the earth. One of the greatest things is it keeps spefic gasses needed for life like oxygen in the world.
Tendons :may also attach muscles to structures such as the eyeball. A tendon serves to move the bone or structure. A ligament: is a fibrous connective tissue which attaches bone to bone, and usually serves to hold structures together and keep them stable.

The given blank can be filled with gas exchange.
In the mentioned diagram, the magnified structure shown is of alveoli. Alveoli are an essential component of the respiratory system that functions to exchange the molecules of carbon dioxide and oxygen to and from the bloodstream. These are the tiny-balloon configured air sacs situated at the very terminal of the respiratory tree and are aligned in groups all through the lungs.
Passive transport means the cell does not have to spend energy to move gasses and fluids. the gasses or liquids go from a higher concentration to a place of lower concentration. Think about shaking a can of soda. There's a lot of pressure that builds up in the soda. When you open the soda, all of the pressure escapes to an area of lower pressure outside of the can. This is called diffusion. Osmosis is another form of passive transport. For example, in water osmosis, the water goes from a less salty solution to a more salty solution.
The correct answer is A. Diffusion and osmosis.
hope this helps =)
