The table shows the amino acid present at ten positions in the myoglobin protein in five different organisms. based on this evidence, a researcher could conclude that a) the two closest relatives are lemurs and gibbons. b) cows are more closely related to gibbons than they are to pigs. c) the myoglobin of pigs and cows is more similar than the myoglobin of lemurs and gibbons. d) no amino acids at any position of the myoglobin protein remained

water is a polar molecule. a chemical bond is a force of attraction between atoms or ions. bonds form when atoms share or transfer valence electrons. atoms form chemical bonds to achieve a full outer energy level, which is the most stable arrangement of electrons. so, false

explanation:

in h2o molecule, two water molecules are bonded by a hydrogen bond but the bond between two h - o bonds within a water molecule are covalent. the greater the electronegativity difference, the more ionic the bond is. bonds that are partly ionic are called polar covalent bonds. nonpolar covalent bonds, with equal sharing of the bond electrons, arise when the electronegativities of the two atoms are equal.
