Coiling of shells can vary for snails. snails that coil to the left cannot mate with snails that coil to the right. this difference leads to reproductive isolation. what kind of reproductive isolation does this example indicate? mechanical isolation postzygotic isolation gametic isolation behavioral isolation

Its mechanical isolation. i checked on plato

Mechanical isolation

Explanation:

Mechanical isolation occurs when the reproductive structures of organism are not compatible. In this example, the coiling on the shells do not match, therefore the snails cannot reproduce.

Postzygotic isolation occurs when organisms have already fertilized an egg, but the offspring either died or was sterile.

Gametic isolation is when the gametes (egg cells and sperm cells) of organisms cannot produce offspring.

Behavioral isolation is a difference in reproductive behaviors such as mating calls that results in two organisms to refrain from reproducing with each other.

None of these apply except mechanical isolation.

videntify the dna change shown in the diagram and explain how that change can result in the increased genetic diversity often seen among siblings.identify the dna change shown in the diagram and explain how that change can result in the increased genetic diversity often seen among siblings.

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.
