Answer:
Angioplasty
Explanation:
Angioplasty is a technique of mechanically widening narrowed or blocked blood vessels. In angioplasty the doctors insert a deflated balloon in the narrowed vessel and then inflate it to fixed size. Thats why it is also known as baloon angioplasty.
Balloon push the walls of vessels for increases blood flow. Sometime a stent is also inserted immediately after angioplasty to ensure that blood flow remain intact and balloon is removed by deflating it.
Angioplasty may of several types depending upon the blood vessels it open such as coronary angioplasty, peripheral angioplasty and renal angioplasty.
To receive oxygen. Basically to breathe.
Answer:
They adapted with new traits to survive to new environments.

<span>The Cell theory states that..
1)all living things are composed of one or more cells 2)cells are the smallest units of structure & function of living things 3)New cells are produced by preexisting cells
The 2 Domains that include all organisms that are made of prokaryotic cells are-
bacteria and archaea. these organisms are multicellular and may form colonies
cytoplasm fluid part of the cell
plasma membrane : membrane surrounding the cell
ribosomes : solid,molecular organelles that make proteins
Circular DNA molecule in prokaryotes where genes are found
plasmids
cell wall
rigid structure around plasma membrane
Used for swimming (moving) through a liquid
flagellum
used to adhere to surfaces (like your teeth) fimbriae
as a cell increases in diameter, its volume increases more than its surface area. the surface area to volume ratio is reduced
since the surface is where the cell exchanges substances w/its environment, the reduction in this ratio decreases the rate of exchange. thus making cell work less efficient</span>
