Diuris are common orchids found in Australia. The flowers of this species display a large number of variations in color and mark
Strike441 [17]

From what we know, we can confirm that the variations in colors are a mechanism intended to protect the plants from predators.

<h3>Why is color a protection mechanism?</h3>

This can be observed throughout nature. Many poisonous organisms have evolved bright colors intended to be noticed. Over time, this has resulted in many predators avoiding prey with bright colors, in order to avoid the possibility of being poisoned.

Therefore, we can confirm that the variations in colors are likely a mechanism intended to protect the plants from predators.

A chemical reaction produces two new substances, and each product has a mass of 25 grams. What was the total mass of the reactan
hodyreva [135]
Well, according to the law of conservation of mass, the total mass of the reacting atoms must equal the total mass of the final rearranged products produced through the reaction. Assuming that both products are the only products produced, it would constitute the total matter produced, and since each product has a mass of 25 grams each. The total would be 50 grams. Thus the total mass of the reactants also would need to be 50 grams, as no matter is lost in a chemical reaction.
