Too much fertilizer can ruin the earth because it releases methane gas which it harmful for the envoronment
Answer:The only difference between a molecule of a compound and a molecule of an element is that in a molecule of an element, all the atoms are the same. For example, in a molecule of water (a compound), there is one oxygen atom and two hydrogen atoms. But in a molecule of oxygen (an element), both of the atoms are oxygen.

Answer:
The correct answer is option d.
Explanation:
In a fish, the heart comprises two chambers, a ventricle, and an atrium. The deoxygenated blood comes through the body, moves into the atrium and then into the ventricle, from where it is pushed towards the body through the gills.
The pumping of the blood via the heart takes place via the capillary beds of the gills and via the tissues’ capillary beds. When the blood come in the capillary beds of the gills it gets slow down. It moves gradually via its path to the tissues and requires skeletal muscular activity to help the blood to mediate towards the heart again. Thus, a fish is dependent upon the physical effort for blood to get circulated again to the heart.
The heart of an amphibian-like the frog exhibits three chambers, two atria and one ventricle. In the process of circulation, that is, in the ventricle, the oxygenated and the deoxygenated blood gets mixed prior to being impelled out of the heart. However, amphibians possess lower metabolisms and thus, they need less oxygen. The requirement of a lesser amount of oxygen puts less pressure on the heart to provide blood with high oxygen. Thus, a heart comprising three chambers is suitable for the requirements of amphibians who could absorb oxygen via their moist skin.
