Answer:
True.
Explanation:
Genetic drift occurs when a species migrates into another one, therefore making a new variation of the species.
The answer could be any of the following:
* energy
* sugar
* carbohydrates
* (possibly even) food.
It supports it by saying that there was once only one mammal but then it reproduced and since different places have different climates they adapted or evolved to the climate changing their form and shape.
Answer: Transcription factors
Explanation:
The dioxin enters the blood stream and the fat cells and liver cells store it.
While moving inside the cell the dioxin binds to the protein called Aryl hydrocarbon which then binds to the second receptor.
The complex is then carried to the nucleus of the cell. This tends to on and off certain genes.
This turning on and off of the genes in the cell can lead to serious diseases like cancer, decreased immune function, et cetera.
