<span><em>Whether living or non living:</em>
<em>When you put a sample of tissue under a microscope, if u can see a cell membrane, and can identify some cell structures like nucleus, mitochondria, vacuoles etc. , it was living, if not, its a non living thing.</em></span>
<span><em>However some cells don't have a nucleus( eg. prokaryotic cells), but all cells have a cell membrane or some sort of protective covering to contain the cell's insides. </em></span>
<span><em>To check if your specimen maybe-once living, maybe-still living "something", is living, get a look at it through an electron microscope - thats the best microscope ever- and see if the mitochondria's making any ATP( adenosine triphosphate, source of energy for most organisms), if it does, its living. If not, no</em></span><em>n living. :)</em>
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.
False, because most organisms decompose fairly quickly after they die. For an organism to be fossilized, the remains usually need to be covered by sediment soon after death. hope this helps :))
