The answer is iron. Research has shown an increase in serum iron concentreation in athletes and a concomitant decrease in magnesium ions. The increase in iron concentration is thought to be attributed to tissue injury from the strenuous physical activity. The decrease in magnesium is due to demand by the skeletal muscles.
According to the image, the fish underwent sympatric speciation. The new species of fish had mating seasons that were different from that of the original fish. Because of the differences in mating seasons, the fish underwent reproductive isolation. This mode of isolation would be temporal.
Sympatric speciation happens within a population of an organism that gets isolated reproductively due to differences in their mating periods. This time dependent isolation is called temporal isolation. Example, a fish population can split into two if some of the fishes start mating early in the spring while the rest mate late in the autumn. The spring-mating population will not become compatible to mate with the late-autumn-mating population.
Gas and plasma .............
The correct answer is option D
The energy in the form of heat is absorbed by the water to convert itself into vapour during the process of evaporation. This energy is then released in the atmosphere when the water vapor gets converted into clouds during the process of condensation. From the start of the water cycle , the heat energy of the sun gets converted into the kinetic energy to raise the water vapour to certain height. After reaching heights Kinetic energy is converted into potential energy and then it is finally released to atmosphere after condensation. In the entire process the total energy remains constant it is just being converted from one form to another.
