I believe the answer is: The dark colored moths will experience disruptive selection
The bird prey on moth and possibly identify the moth by visual sense. The moth has two type of color: dark and light. The trees in the area is more light coloured so the black moth will be identified easier as their color is more contrast to the tree. As the dark moth easier to identify, they will be predated more and their population will be reduced. When a trait has advantage than the other, disruptive selection happens.
It's the last one it's featured causing it to produce nothing at 70°c
For the first question, I would say a line graph. And the one about the human heart, I need some more information.
The DNA copies are moved to opposite ends of the cell.
The human activity that creates the least threat to global stability is : Reuse of Plastic bags.
Plastic bag need a lot of time to be degraded in the soil which will create a threat to the environment. Reusing plastic bag will reduce this threat.
hope this helps
