I feel like it’s C. don’t hold me to that
Answer:
The correct answer is ''consists of protoporphyrin and an iron (II) ion.''
Explanation:
The heme group makes up the prosthetic (non-protein) group of hemoglobin and is responsible for its characteristic red color. It is composed of protoporphyrin IX, in the center of which is the ferrous ion (Fe+2). Protoporphyrin IX, in turn, is composed of four pyrrolic rings. The heme group is synthesized by the mitochondria, where protoporphyrin IX binds with the ferrous ion, before being released into the cytoplasm. The heme group is released in erythrocyte lysis, thus obtaining unconjugated or indirect bilirubin.

When toucans are removed from an ecosystem it leads to loss of hardwood trees, deforestation, and global warming.
Explanation:
Toucans are very attractive brightly colored large birds which are fruigivore (fruit-eaters). They are specially adapted with a large, sharp but lightweight bill which helps the toucans to reach to branches to pick fruits, berries, seeds mostly which are larger and difficult for the smaller birds to eat.
Their main habitat for the toucan is the rainforests. They are woodland birds and stay mostly on hardwood trees.
Toucans help the rainforest ecosystem to grow by dispersing the seeds of the fruits they eat all around the forest as they keep flying. This makes the species of trees from which toucans pick their fruits to increase and makes the rainforest healthy.
When toucans are removed, then dispersal of seeds becomes less and spreading of hardwood trees will be reduced slowly leading to deforestation and drying up of forest lands.
Bigger hardwood trees play a major role in reducing carbon footprint compared to the softwood smaller trees and this increase in carbon will lead to global warming.
Answer:
D. A molecule of glucose
Explanation:
Potential energy is defined as the energy that is stored, or conserved, in an object or substance. The act of contracting muscles, emitting light flashes, flying or water moving are all dissipating energy and, thus, do not represent an example of kinetic energy. On the other hand, a molecule of glucose stores energy and therefore is an example of potential energy.
