Please help me! Look at the pictures, answer the questions. 1. Which of the points on the graph is igneous rock?

A or B or C

2. Why does that point represent igneous rock?

A. Because igneous rocks need high temperature and pressure to form.

B. Because igneous rocks don't need any heat, they only need some pressure for sediments to get compacted.

C. Because igneous rocks are made by melted magma cooling, so it must have a high temperature in order for the rock to melt, and medium pressure.

Dominant over the mutant vermilion (bright red) allele. a homozygous wild-type female fly is mated with a vermilion male fly. predict the eye colors of f1 and f2 generations. (assume that the f1 flies are allowed to interbreed to produce the f2 generation.)

Elements and compounds are pure substances that cannot be broken down physically into a simpler substance. a physical change doesn’t break the bonds between atoms of a substance or form new ones. compounds can be broken down by a chemical change. a chemical change breaks chemical bonds and/or forms new ones between atoms of a substance. what simple substance would a compound break into? the basic elements that make it up! for example, if you passed a very strong electric current through water you’d break the chemical bonds in water and be left with oxygen and hydrogen. which of the following is an example of a chemical change? a separating water into different glasses b breaking frozen ice cubes with a hammer c running an electric current through water d boiling water to evaporate it on a stove
