Answer:
B. In fishes, blood passes through the gills, returns to the heart, and then is pumped to the systemic tissues.
Explanation:
In fish, blood does not pass through the gills, returns to the heart and is then pumped into the systemic tissues.
Most fish breathe through gills. Water continually enters the fish's mouth, bathes the gills and exits through the openings on either side of the head. Most fish breathe through gills, also known as gills. Water continually enters the fish's mouth, bathes the gills and exits through the openings on either side of the head.
The heart of the fish has two cavities, an atrium and a ventricle - and through it only unoxygenated blood circulates. After passing through the heart, unoxygenated blood goes to an artery and into the gills where it receives oxygen gas. This now oxygenated blood is distributed to all organs of the animal's body.
Answer:
The earth system usually refers to the different ways in which various physical, chemical as well as the biological processes interacts with one another and it includes the land areas, oceans, atmosphere, minerals and also the different cycles such as carbon, nitrogen, sulfur and so on.
These processes are continuously taking place at, on and below the surface of the earth, maintaining an equilibrium. The life existing on earth is directly dependent on these conditions and on-going processes. When there occurs changes in these conditions, then the lives on earth are affected.
For example, the lives are dependent on the climatic conditions, and when suppose the concentration of green house gases and other toxic elements are increased in an ecosystem, then the temperature will eventually rise, and there reaches a point when it becomes difficult for life to sustain. The organisms will suffer from different diseases.
Thus, the growth of life on earth affects when there occurs changes in the earth's system.
