PPT-Presentation on cleavage

Definition Cleavage is a process of rapid and synchronous mitotic cell divisions of the zygote to form numerous cells for building up the offsprings body Cleavage differs from other forms of cell division in that it increases the number of cells without increasing the mass.

Moh’s scale – developed by Austrian mineralogist Friedrich Mohs in 1824. Absolute scales – Brinell, Knoop, Rockwell, Vicker’s. 3. Moh’s Scale. . A mineral is naturally occurring homogeneous inorganic substance having distinctive physical properties and a more or less definite chemical composition.. Minerals are to a large extent the units which make up the rocks of the earths crust or the outer shell.. 1 Mineral Properties GLY 4200 - Lecture 2 –Fall, 2019 © D. L.
