Adecrease in the level of which hormone releases seeds from dormancy?
abscisic acid
cytokinin
ethylene
gibberellic acid

abscisic acid

Explanation:

Abscisic acid is a plant hormone also known by the acronym ABA, whose function is growth inhibition and stomatal closure. We can also attribute to abscisic acid the function of delaying seed germination in the process known as vegetable dormancy. Usually the accumulation of this hormone happens at the beginning of the development of some seeds and is related to delayed germination.

Abscisic acid induces seed dormancy, but decreasing levels of this hormone release seeds from dormancy.

ionic bonds are two oppositely charged ions that attract. a sodium ion has a 1 positive charge; a chloride ion has a 1 negative charge. sodium and chloride have oppostive charged ions that attract which forms an ionic bond. a chemical bond formed when two atoms share electrons is called
