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.
Blonde hair. This is because phenotype means physical trait, or one you can physically see. BB Bb and bb are all genotypes
<em>C. Binding to the operator.</em>
Explanation:
When the repressor starts binding to the operator, it can not transcribe, or make mRNA. This makes it so the RNA polymerase can't go onto the promoter and bind to it, which is a crucial part in making mRNA. The operator functions by making sure the certain DNA gets made, so it is very important. The lac repressor will turn off the expression of the lac genes by binding to the operator.
Answer:
i think this is how they will look like
