Which event can the student best demonstrate with their model?

Answers

Answer:

C Earthquake

Explanation:

I just took this test and it’s on Quizizz

The event which best describes the model is an Earthquake. Earthquake is

formed when two plate boundaries collide with each other.

The plate boundaries colliding results in them being stuck. Pressure then

builds up between them which results in the plates breaking loose as time

goes on.

The movement that results from the plates breaking loose is what results in

an earthquake being experienced.

In chemical reactions, what does the principle of conservation of mass mean?

Answers

I think It means that any balanced equation is conserved. Meaning that the equation is equal. The law states matter can’t be created or destroyed. In chemical reactions the mass of an element is the same before and after the product. There’s two sides two an equation the reactants side and the product’s side. Hope this helps.
Principle of Conservation of Mass
In simple terms, it means that in a chemical equation, the mass of the reactants is same as mass of products. No mass is created, and cannot be transformed.

Answers

Answer:

In the first generation, the beetles changed to have light spots. The beetles with the light spotted trait had a better chance of survival causing the species evolved to have lighter spots.

Answer:

In the first generation, the beetles with the dark spotted trait had a better chance of survival. The trait mutated over time, causing the beetles with that trait to be darker.

Explanation:

In the picture that I had, it shows that some of the beetles in the first generation started to develop spots on their back or wings. It shows that later down the line, their backs start to get even more darker which means that is must be a trait that mutated over time that would allow the beetles with that trait to be significantly darker. They can't just change their traits if they want to so it would have to be something like mutation that caused it.
