Lt: compare and contrast mitosis and meiosis.

Meiosis has two rounds of genetic separation and cellular division while mitosis only has one of each. In meiosis homologous chromosomes separate leading to daughter cells that are not genetically identical. In mitosis the daughter cells are identical to the parent as well as to each other.

5 similarities. 
1. they both involve division of a cell. 
2. the processes of division are the same. (anaphase, metaphase, etc.) 
3. replication of chromosomes occurs before division. 
4. same number of chromosomes at first divisions 
5. two sets of chromosomes for both are enclosed by the nuclear envelope. 

5 differences. 
1. resulting number of chromosomes are different 
2. homologous chromosomes pair up before division for meiosis. 
3. mitosis occurs for somatic (body) cells and meiosis occurs for gametes. 
4. meiosis is twice the division of mitosis. 
5. overlapping of chromosome pairs occurs only in meiosis

Alright, i'm gonna try to explain this as good as possible. the law of conservation is like a collection overtime. it never changes though. no matter how you change the constituent parts.
