Which of the following accurately describes a chief difference between eukaryotic and prokaryotic cells? A. Eukaryotic cells contain a distinct, enclosed nucleus while prokaryotic cells do not.
B. Prokaryotic cells contain a distinct, enclosed nucleus while eukaryotic cells do not.
C. Prokaryotic cells are found in and on animals while eukaryotic cells are found in and on plants.
D. Prokaryotic cells are found in and on plants while eukaryotic cells are found in and on animals.

A. Eukaryotic cells contain a distinct, enclosed nucleus while prokaryotic cells do not.

Explanation:

prokaryotic cells lack membrane bound organelles

hope this helps

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.
