Using the information from problem 4, scientists do a further testcross using a heterozygote for height and nose morphol- ogy. the offspring are tall-upturned snout, 40; dwarf-upturned snout, 9; dwarf-downturned snout, 42; tall-downturned snout, 9. calculate the recombination frequency from these data, and then use your answer from problem 4 to determine the correct order of the three linked genes.

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.

Cells must be in osmotic equilibrium with their surroundings environments because if they swell or shrink thier membranes will rupture
