The cell organelles are the functional structures present inside the cell. Some of the organelles such as nucleus, mitochondria, chloroplast, Endoplasmic Reticulum, Golgi Complex etc are membrane-bound. Each organelle inside the cell has a different function to carry out. For example, the nucleus is the organelles which stores and protects the genetic material. Ribosomes are the organelles where a protein is formed. The Golgi- complex is the site where the proteins are modified and packaged.
It causes a much more gradual decrease in hardness with position from the quenched end.The presence of alloying elements (other than carbon) does not influence on the shape of a hardenability curve.It causes a much more rapid decrease in hardness with position from the quenched end.
The correct characteristics of the given objects are as follows:
A: Jupiter - electromagnet (The electromagnetic waves around Jupiter are much stronger around two of its moons)
B: Refrigerator magnet - permanent magnet (The magnets that we affix to our refrigerator are permanent magnets)
C: Mars - Not magnetic ( Mars has no inner dynamo to create a major global magnetic field.)
