Answer: it was necessary to see data from more plants before the conclusion could be accepted
Explanation: i got it right
Density Change is when the mass/weight of an object modifies by sometimes its environment. It relates to pond life by how much weight thats in the pond and the mass of creatures, such as frogs and crocidiles
Opioid receptors interact with G proteins and arrestin. In consequence, opioid receptors interact with protein biomolecules.
<h3>Proteins and opioid receptors</h3>
Proteins are fundamental biomolecules composed of long chains of building blocks called amino acids linked by peptide bonds.
Proteins may have both structural (e.g., components of the cytoskeleton) and enzymatic functions (in this case, activation of signaling pathways).
Opioid receptors interact outside the cell membrane with opioid drugs (e.g., heroin) and with the G proteins inside the cell.
Opioid receptors also interact inside the cell with a special protein that is known as arrestin, thereby activating specific signaling pathways.

Explanation:
Basically, lac operon is an enzyme, and enzymes work in a very well known way called lock key system
. This lock key system works pretty simply, imagine the lock as the enzyme, and this lock needs a specific key to open it, thinking about an enzyme, it needs the specific substrate to breakdown the lactose, this enzyme is called lactase, and it's present in some animals and bacterium too. This doesn't only work for lactose, it's the same lock system for every enzyme, all of them need specific substrate to break it down into things that the body can use for many things.
