There are 5 different levels of cellular organization.
Cells, tissues, organs, organ systems and whole organisms. Cells hold genetic material and absorb outside energy.
Tissues make up the bones, nerves and connective fibers of the body. Organs work to perform specific bodily tasks, such as filtering blood. Organ systems are groups of organs that perform a specific kind of function together, such as digesting food.
Together, these smaller systems make up an entire living organism which can grow and then go onto reproduce.

The pit that marks the location of the umbilical cord after birth is known as the navel or belly button. All animals that grow placenta during fetal development will have a navel or belly button. The scientific name of the structure is the umbillicus. It can be a depression in some individuals or raised in others.
Answer:
Explanation:
Cl = 1s2 2s2 2p6 3s2 3p5
Al = 1s2 2s2 2p6 3s2 3p1
Fe2+ = 1s2 2s2 2p6 3s2 3p6 4s2 3d4
S2- = 1s2 2s2 2p6 3s2 3p6
Diamagnetic materials are repelled by a magnetic field; an applied magnetic field creates an induced magnetic field in them in the opposite direction, causing a repulsive force. If all electrons in the particle are paired, then the substance made of this particle is diamagnetic.
S2- is diamagnetic because of its paired electrons in the outermost shell.
