In multicellular organisms, the shape of the cell helps determine its function. For example, red blood cells are donut-shaped to easily exchange oxygen and freely pass through narrow blood vessels while nerve cells are long so when connected to other nerve cells they can span long distances in the organism

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.
Answer:
Elements have the same number of energy levels, Elements change from reactive metal to unreactive nonmetal, Rows 1-7 on the periodic table
Explanation:
The powerhouse of the cell: That is a term used to describe the MITOCHONDRIA, because its main function it to produce energy for cellular activities.
Mitochondria is the host of cellular respiration. This is where the Mitochondria take in glucose and oxygen to produce energy and is distributed all throughout the body as energy-rich molecules of ATP.
