Report Abuse. A lysosome is like the cleanup crew of the cell. One of its functions is the digestion of lipids, carbohydrates, and proteins into small molecules that can be used by the rest of the cell. Lysosomes are also involved in the breakdown of organellesthat have outlived their usefulness. Source(s): My biology book :).
What is spinal muscular atrophy (SMA)? SMA is a rare genetic neuromuscular disease that affects the part of the nervous system that controls voluntary muscle movement. In spinal muscular atrophy, there is a loss of important cells in the spinal cord called motor neurons, which are essential for muscle strength and movement.
Shape-memory alloy. A shape-memory alloy (SMA, smart metal, memory metal, memory alloy, muscle wire, smart alloy) is an alloy that remembers its original shape and that when deformed returns to its pre-deformed shape when heated. This material is a lightweight, solid-state alternative to conventional actuators such as hydraulic, pneumatic, and motor-based systems.
