How do little elephants grow up to be BIG elephants?
Why do animals shed their skin?
The process of asexual reproduction begins after a sperm fertilizes an egg.
Three reasons why cells reproduce by asexual reproduction: 1. Growth 2. Repair 3. Replacement Skin cancer - the abnormal growth of skin cells - most often develops on skin exposed to the sun. Cell that reproduce by asexual reproduction reproduce constantly.
The Cell Life Cycle Gap 1 - Doubling of cell size. Regular cellular activities. transcription and translation etc. S G 1, S, and G 2 are collectively called INTERPHASE Synthesis of DNA - Regular cell activities cease and a copy of all nuclear DNA is made G 2 M Gap 2 - Final preparation for division Mitosis - Cell division
Mitosis • Prophase • Metaphase • Anaphase • Telophase & Cytokinesis

Cytokinesis occurs after mitosis • Cytoplasm divides in half to allow the two cells to separate from each other

What is the end product? An EXACT copy a of “mother” cell produces 2 “daughter” cells
