DRAW IT Indicate the response to each condition by drawing a straight seedling or one with the triple response.

Welcome back. Let's look at our next question. Ethylene hormone is responsible for short shoots, fat shoots and increased lateral root growth in ceilings. It is referred to as a leafs in essence be triple response. See A pickle dominance, E. Or B. D. Bud dormancy. So let's walk through those answers. A leafs in essence that does involve ethylene. Ethylene kind of stimulates that process leafs in essence is when you have uh in the fall leaves changing and and falling off uh causes the re absorption of the salutes in that leaf and the dismantling of its structure. But that is not part of these three processes that we see up here involving seedlings involving shoots and root growth. So even though leaf senescence involves ethylene, it's not the process we're looking for. So we can eliminate that choice. B says triple response. Well we've got a clue in the name. Triple. These are three things that happen in response to ethylene shoots becoming shorter shoots becoming fatter and increased lateral growth. And the triple response is indeed the name of that response to ethylene. Finally they just look at our last two, A. Pickle dominance E. And bud dormancy. These two things are connected. Um They happen as the stem is growing and the buds down lower remain dormant. That's bud dormancy whereas the buds up higher on the stem towards the typical part of the stem um are allowed to be allowed to blossom. So are allowed to grow. So both of those things are connected. But they are a result of the hormone oxen, not ethylene. So we can eliminate C and D. Again. Our correct answer here is the triple response to the hormone ethylene. Thanks for watching.
