What is an isolating mechanism and how does it create a situation leading to speciation?
Water (islands), mountains, as well as deserts act as isolating mechanisms. Continental Drift resulted in the isolation and subsequent development of animals that are genetically quite different that fill similar niches in the isolated environments. A comparison of animals that fill similar niches in Australia as compared to the US or Africa yields Kangaroos and Wallabies that fill the same niches as deer and antelope. Initial speciation begins as as better adapted animals occupying a niche push the marginalized individuals out into other areas where any unique genetic characteristics or mutations that make them better able to adapt to a new niche are selected for based on survival rate.
If i have the initial and after temperature how would i be able to find the change in temperature?
You subtract the initial from the after, and the result is the change. If the initial temperature is 50º and the after is 70º, then the change is +20º.
What is the initial site for respiration?

What is the definition of initial observation?
Initial observation means the first time you perceive something and register it as significant.

What was the initial speed of a car that required 19 m to stop in 7.5 s?
There is not enough information. The stopping distance depends on the conditions of the road, the brakes, the tyres. At one extreme, even a car travelling at an initial velocity of 100 km per hour will probably stop if 19 metres in front of it is a concrete security barrier!
How do you say initial in German?
it depends on the context initial (as your initials) - Initial initial (as in first) - erste/erster/erstes

How does a particle tunnels through a barrier?
In a purely classical world, the probability of a moving particle getting through an electro-static barrier was simple: if the kinetic energy of the particle was greater than the charge times the voltage, it was 100% likely to get through, if the KE was less, the probability was zero. In the latter case, the ball would simply bounce back, because the energy level of the voltage barrier ( 'E(vb)' ) was simply too large for that particle's KE to overcome When you do the mathematics of the Schroendinger Equation with this situation -- a charged particle meeting a voltage barrier -- you can no longer talk about what WILL happen with 100% certainty. You can only discuss the PROBABILITY of something happening. For example, even if the electron has more KE than E(bv), then there is some chance that it will bounce back. When a moving electron meets a voltage barrier, in which the initial KE is smaller than E(vb), then the probability of finding that electron in that barrier goes down fairly rapidly. If the barrier is thick, then the probability of finding the electron in that area of high voltage goes down to zero. On the other hand, it CAN happen that, for a thin barrier (or a fast electron or a voltage barrier not too large), that the probability of finding an electron beyond the barrier does NOT go down to zero. In that case, you have quantum tunnelling. The mathematics are fairly complicated; but have been shown to agree with experiment.
