Which species is least likely to become extinct? a. A mammal species that can live equally well on dry land and in fresh water b. A fish species that has hybridized with another species to produce infertile offspring c. A fish species found in all five of the Great Lakes d. A mammal species that feeds on a rare tropical orchid e. A fish species that feeds on only rare snails found in only one small river Submit

a. A mammal species that can live equally well on dry land and in fresh water

Explanation:

Species need favorable conditions to thrive, reproduce,  and survive going extinct from an environment. When such conditions change in an environment, and the species in that environment are unable to evolve along with such changes to become adapted to survive, they go extinct.  

From the options given in the question, the least likely to become extinct is a mammal species that can live equally well on dry land and also in fresh water, as they would be well adapted to changes that occur in their habitat .

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.
