Brown eyes are a dominant eye-color (B) and blue eyes are recessive (b). Look at the following pedigree. A brown-eyed woman marries a brown-eyed man. They have a son who is blue-eyed. The phenotypes of their parents are indicated in the pedigree for generation 1. Shaded shapes indicate blue eyes. A. What are the genotypes of the individuals in this family tree? Be sure to list each possibility if more than one genotype is possible. Fill in the table with the genotypes for each individual represented in the pedigree.

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

If scientists are wrong about earth's age based on radioactive material and the decay rates are really much faster, how would nuclear power plants be affected?
