Compare "lack of contact inhibition" in cancer cell and innormal
cell.

Normal cells stop dividing when they come into contact with similar cells, while cancer cells do not.

Explanation:

Cancerous tumors are characterized by cell division, which is no longer controlled as in normal tissue. "Normal" cells stop dividing when they come into contact with similar cells, a mechanism known as contact inhibition. Cancerous cells lose this ability.

In cancer cells, the self-regulation system that controls and limits cell division is unbalanced. The process of cell division, whether in normal or cancerous cells, is carried out through the cell cycle. The cell cycle goes from the resting phase, through the active growth phases, to mitosis (division).

answer: grassland biomes are closer to the equator and receive more rain.

grasslands are biomes that are dominated by grasses rather shrubs and trees. savanna are biomes that exhibit grasses, shrubs and small tree as vegetation. grasslands are located near the equator of the earth. these are found in north america. savanna biomes are found in africa, south america, australia and india. grassland exhibit moderate climatic conditions, it receives   amount of rainfall higher than savanna.   therefore, savanna exhibit dry and hot climatic conditions.
