3. a pea plant purebred to produce round yellow peas is crossed with a plant purebred to produce wrinkled green peas. round pea
shape is dominant to wrinkled, and yellow pea color is dominant to green. members of the resulting f1 generation are then crossed to
produce an f2 generation, as shown in the figure. on average, what fraction of the f2 generation will display both recessive traits?
a. 6 out of 16 plants will display both recessive traits
b.0 out of 16 plants will display hoth recessive traits
c. 4 out of 16 plants will display both recessive traits
d. 1 out of 16 plants will display both recessive traits.

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
