During inter-phase of cell division, the genetic material is duplicated to allow for division into 2 identical daughter cells. The tumour suppressor gene checks for errors in the DNA, and if found, apoptosis (cell death) is initiated by p53 protein. The pRb (retinoblastoma) protein stops the progression of the cell cycle form G0 into S phase if the cell division is complete hence stemming unregulated cell division.
Answer:
Through different studies scientist have quantified the amount of energy that moves to the next trophic level. Most of the energy is used for metabolic processes and released as heat to the environment.
The amount of energy left for the next level is around 10%, if a herbivore takes 1,OOO Kilojoules the energy left for the next level would be around 100 Kilojoules, this explains why you cannot find a food chain with more than 7-8 levels (ocean) on land is usually between 4-6 levels.
