Speciation is the creation of a new species distinct from the original due to evolution.
I will walk through how this will work for you.
1. Animals of the same species living on either side of a stream can move from one side to another.
2. The stream changes into a river
3. Animals are now separated and must live apart
4. Environments on either side of the river change over time.
5. Animals due to natural selection, undergo change
6. After a thousands of years, two different of species form.
Hope this helps.
The right answer for the question that is being asked and shown above is that: "<span>Read the observation, question, and hypothesis. Then, choose the dependent variable from the list. Dependent variables are those variables that depends on the independent variable in order to get the output."</span>
The part of the eye that acts as a secondary area of refraction to fine tune the focus is the lens. The lens of the eye is a biconvex, transparent structure of the eye that helps in refraction along with the cornea. Most of the refracting of the light rays happens in the cornea, but the lens help refract light to be focused on the retina by changing its shape to focus on objects at various distances.
