Answer:
In order for scientists to keep track of endangered species and discover new species that are created due to the constant change.
The answer to that question would be false as there are major differences between how the food grows as in growth rate, mass, and texture and taste; and what kind of nutrients and chemicals you'd be putting into your body such as conventionally are like GMOed for various reason to make certain characteristics while you maybe also eating chemicals produced thereof because of so that isn't necessarily healthy for you to consume whereas organically grown produce is likely to be smaller and disformed at times, and don't always have abundant crops with the acasional bug. So to answer your question Yes there are major differences between organically and conventionally grown vegetables.
Exothermic reactions lose heat and are hot to the touch (Think explosion)
Endothermic reactions gain heat and are cold to the touch (Think of an instant ice pack where you pop it to make it cold)
Different responses triggered by thyroxine in different organisms is most likely due to different kinds of receptor and consequently different signal cascade and response.
The thyroid hormones (including thyroxine) bind to a specific types of nuclear receptors, termed the thyroid hormone receptors which together with corepressor molecules, bind DNA regions called thyroid hormone response elements.
