Scientists are discovering that many tissues and organs contain a small number of adult stem cells<span> that help maintain them. </span>Adult stem cells<span> have been found in the brain, </span>bone marrow<span>, blood vessels, skeletal muscle, skin, teeth, heart, gut, liver, and other (although not all) organs and tissues. They are thought to live in a specific area of each tissue, where they may remain dormant for years, dividing and creating new cells only when they are activated by tissue injury, disease or anything else that makes the body need more cells.</span>

Would a muscle cell be able to produce a functional contraction if it lacked t-tubules?
hjlf

The answer would be no. T-Tubules or Transverse tubules are additions of the sarcolemma that infiltrate into the center of cardiac and skeletal muscle cells. There would be no functional contraction since it would not be capable to communicate or interconnect with the other cells.

What are the effects of animal cells placed in a hypotonic and isotonic solutions? What about plant cells placed in those soluti
AfilCa [17]
Hypotonic solution means a solution with a higher water potential than the cell
isotonic is the solution with the same amount of water potential with the cell
in animal cell, it only has a semi permeable membrane, therefore when put in hypotonic solution, water molecules will move from the solution to inside the cell by osmosis. the cell may gain so much water that it may burst
in isotonic solution, the net movement of water molecules will be same in each direction , as the water potential is same. that way the cell will not gain or loss water and remain it oiriginals shape
however in plant cells, it has a cell wall. it prevents the cell from bursting. so when put in hypotonic, the cell gain water,but not burst, the cell membrane just push against the cell wall and the cell become turgid
in isotonic solution, same animal cell , no change
