Answer:
Hey there!
In an experiment, we have independent and dependent variables. Without them, there wouldn't be an experiment!
The independent variable is the variable that is being changed. For example, in this experiment, the temperature of the salt solution is our independent variable is changing (increasing in this case)
The dependent variable is what changes when the independent variable changes. The change of the dependent variable is always caused by the change in the independent variable. In this experiment, the amount of salt dissolved in water is the dependent variable, because it is changing as the independent variable is changing.
Let me know if this helps :)
Answer:
Speciation was allopatric or peripatric, but would depend on the number of individuals that dispersed from the original populations.
Explanation:
- There are two types of speciation: allopatric and peripatric.
- Allopatric speciation occurs when the species of same population gets isolated that results in lack of gene flow.
- From the isolated population, new species are formed then it is known as the peripatric speciation.
- All these isolation of populations and formation of new species depends upon the initial or original group of species that was dispersed.
Physical Change, although the answer is widely disputed.

I'm not sure what a wood trush is, but biotic means to be alive so for example a bird or tree if it's a forest, and abiotic meand not living for example a rock, water, or sunlight. Hope that helps!
