Scenario: Before the industrial revolution in England the predominant peppered moth had light colored wings. After the industrial revolution more dark colored moths appeared until they were the dominant form of
the moth. The major predators of these moths were sparrows that relied on sight to identify and eat the
moths.
The light colored peppered moths in the forest of the industrial area began to disappear in numbers because
they were...
A Very sensitive to the sooty air pollution
B Poisoned from eating the soot covered lichens
C More visible against the dark tree bark
D Repelled by the dark bark tree since the lichens had died.

Always use significant figure rules. remember that these rules apply to all numbers that are measurements. if a vector that is 3 cm long represents 30 km/h, what velocity does a 5 cm long vector which is drawn using the same scale represent? a.100 km/h b.60km/h c.50km/h

Which of the following are the functions of the skeletal system? blood cell production in soft marrow tissues and mineral reserves largest organ of the body for defense and support vitamin d production and pumping blood through vessels voluntary movement and contractile movement

What best explains whether bromine (br) or neon (ne) is more likely to form a covalent bond? bromine forms covalent bonds because it has seven valence electrons, but neon has eight valence electrons and already fulfills the octet rule. bromine forms covalent bonds because it has many electron shells, but neon has only two electron shells and is tightly bound to its electrons. neon forms covalent bonds because it can share its valence electrons, but bromine has seven valence electrons and can gain only one more electron. neon forms covalent bonds because it has only two electron shells, but bromine has many electron shells and will lose electrons in order to fulfill the octet rule.
