Ants carry dead ants out of the anthill and dump them on a "trash pile." If a live ant is painted with a chemical from dead ants, other ants repeatedly carry it, kicking and struggling, to the trash pile, until the substance wears off. Which of the following best explains this behavior?a. The chemical triggers a fixed action patternb. The ants have become imprinted on the chemicalc. The ants continue the behavior until they become habituatedd. The ants can learn only by trail and errore. The chemical triggers a negative taxis

A. the chemical triggers a fixed action pattern

Explanation:

Konrad Lorenz, who is the founder of the fixed action pattern, described it as an instinctive behavioral sequence that is highly stereotyped and species-characteristic. Fixed action patterns are said to be produced by the innate releasing mechanism, a "hard-wired" neural network, in response to a sign stimulus or releaser. Once released, a fixed action pattern runs to completion.

Fixed action patterns have been observed in many species, but most notably in fish and birds

Fixed action patterns have been shown to be evolutionarily advantageous as they increase both fitness and speed. However, as a result of their predictability, they may also be used as a means of exploitation. An example of this exploitation would be brood parasitism.

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.
