The correct answer is - one-half.
In the past century, the deforestation of the rainforests in the world had been devastating, and it is estimated that approximately one half of the tropical rainforests have been destroyed.
The reason for the large scale destruction of the rainforests is mainly because of clearing space for agriculture and for spaces where the cattle can graze. Unfortunately, the people that live the regions where the tropical forests are, are not well educated as to how to manage the land, and a big problem is that the soil of the rainforests is only good for 2-3 seasons, because it spends and erodes very quickly. Because of that, people just continue to clear more and more of it, thus leaving destroyed forest and destroyed soil behind them, without taking in consideration the long term effects.

Growth factors are hormones, proteins, or steroid molecules that regulate many cellular functions. They can stimulate the cell division by giving the signal to the cell to progress in the cell cycle.
<u>Explanation</u>:
Growth factors are naturally produced within the body and travels through the body to bind to their receptors present on their target cells. These growth factors are capable of signalling the cell to divide, proliferate, or heel. Their main aim is to signal or tell other cell when to do and what to do. Due to the binding with the receptors the growth factors activates specific genes.
The purpose of studying and dissecting an earthworm is to help us understand other organisms. Earthworms are organisms that are tube-shaped, segmented worms that belong to the phylum Annelida and in the species Lubricous. Earthworms decompose organic matter, break it into usable nutrients for their local ecosystems and recycle compost.
