Answer:
prey and predator
Explanation:
The predator-prey relationship is one of the most common examples of coevolution. In this regard, the predator have adaptations that enable them to capture and feed on their prey. These include many have sharp claws and canine teeth, many are able to run fast and many have a body colour which matches that of the surroundings. There is an increased prey on the prey to avoid being captured by the predator and thus evolved traits to help them camouflage better.
As the peppered moth evolved over time, its wings changed from light to dark so that it could better hide from predators. The evolution of peppered moth is used an example of natural selection. The evolution of the peppered moth over the last two hundred years has been studied in detail. Originally, the vast majority of peppered moths had light coloration, which effectively camouflaged them against the light-colored trees and lichens which they rested upon. However, because of the wide spread pollution during the Industrial revolution in England, many of the lichens died out, and the trees that peppered moths, or typica, to die off from predation. At the same time, the dark-colored, or melanic, moths, carbonaria, flourished because of their ability to hide on the darkened trees.
Proteins which form channels may be utilized to enable the transport of water and other hydrophilic molecules; these channels are often gated to regulate transport rate. In facilitated transport, hydrophilic molecules bind to a "carrier" protein; this is a form of passive transport
It is A) a polymer.
Because Polymer is a large molecule and made of smaller molucules and they are called monomers
