Pea plant clones are given different amounts of water for a three week period.
pentagon [3]

Answer:

independent variable: the different amount of water

Explanation:

The independent variable would be the <u>different amount of water supplied to the pea plant clones.</u>

<em>The independent variable is the variable inputted by the researcher during an experiment whose value directly affects the dependent variable. It is the variable that is manipulated during experiments in order to see the kind of effects they produce on another variable - the dependent variable.</em>

In this case, <u>the amount of water supplied to each pea plant would directly affect the height of the pea plants.</u> Hence, the amount of water supplied to the pea plants is the independent variable while the height of the plants is the dependent variable.

In the last century, the extent of global rain forests has been reduced by _____. one-half
Elodia [21]

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.
