<span>the student could identify the catalyst by noticing the substance that makes a chemical reaction go faster. It will be written in a chemical equation.
Example of Catalyst :
- A corosion process of an iron will be faster if it exposed to Oxygen
- A burning process will be a lot of faster if it mixed with oil.</span>
In the apple maggot fly, the frequency of certain alleles increases steadily as one goes from North to South. This is an example of: Sympatric speciation.
Sympatric speciation is observed when there are no physical barriers which prevent any members of a species from mating with another, and all members are in close contact to one another. A new species, possibly established on a distinct food source or trait seems to develop instinctively.
The example of apple maggot fly supports a model for sympatric speciation in progress. Hawthorn is the native host for the apple maggot fly in North America. However, in the mid-1800s, a new population developed on introduced, domesticated apple.

<span>It is a common misconception that elephants existed the same time as the dinosaurs did when in fact they have evolved 3 or 5 million years after these creatures.
The tusks of the elephant would probably be the structure not present in early elephants. It is only through evolution that these tusks grew. Some scientists have hypothesized that these tusks develop from the elephants' incisors.

Answer:
A decay series ends when a stable nuclide is reached - it will no longer spontaneously decay.
