A source of energy and molecules are required by all living organisms‚ which means that the amount of the cell that is able to receive molecules is important. The group’s hypothesis was that “cells are small because small cells have a larger surface area to volume ratio”‚ which is important because a larger surface area allows for more molecules to diffuse at one time. The group created cells made

Animal extinction Animal extinction has been dramatically occurring and this is the biggest issue in the planet. The governments and scientists try to figure out the better ways to prevent and preserve the disappearance of animals. Human attitudes‚ degradation of nature and climate change are the causes that lead to animal extinction. I think that if these causes are still occurring without protection and preservation‚ the environment will become in less healthy state by 2050. The world human population
