✓whats the difference between the control and the experiment?
-
In an experiment, the control group is the unchanged group and has normal conditions
whereas the experimental group has one variable changed so we can see the result.
The experimental group is compared to the normal/ control group
formal definition: A control group in a scientific experiment is a group separated from the rest of the experiment where the independent variable being tested cannot influence the results

✓what exactly guides you when describing the deffraction pattern?
-
All diffraction patterns have the same description. If you use red light light, then red and dark. Blue light, then blue and dark. But with red, the bands are wider since red has a larger wavelength.

✓Does vapour pressure affect dynamic equilibrium.Explain fully
-
yes,according to the Le chatelier's principles,the equilibrium will move(change the position)in order to withstand/reduce the pressure in the system.example,in this case of having more molecules on the right hand side than on the left side,increasing pressure will cause the equestion to move to the left side to balance the pressure molecule and vice-versa

✓What is the influence of isolating mechanisms?
-
Isolating mechanism is a form of sympatric speciation. (Formation of a new species due to a mechanism of reproductive isolation). This does not allow for the reproduction bet diff species to take place due to: Temporal isolation, courtship behaviour, Adaptations to different Pollinating Agents, prevention of fertilisation because of diff copulatory organs and hybrid infertility.
PS: will email you more info on it, if I have your email address???
