question 36

True/False

As stated in the text, "DNA sequence data indicated that two major subgroups existed within the protostomes." This finding contradicts the long- held hypothesis that the protostomes are a monophyletic group.

Definitions:

Polar Covalent

A type of chemical bond where a pair of electrons is unequally shared between two atoms, leading to a distribution of electric charge across the molecule.

Nonpolar Molecules

Molecules that have an even distribution of electrons, resulting in no permanent dipole moments, and typically exhibit little to no interaction with polar substances.

Nonpolar Bonds

Nonpolar bonds occur between atoms with similar electronegativities, resulting in equal sharing of electrons and no significant charge distribution across the bond.

Polar Solvents

Solvents containing molecules with a partial electrical charge, enabling them to dissolve polar substances.
