Answer:
Explanation:
A food chain is different because it shows what organisms eat in a straight line, in a chain. For example, a bird of prey can eat a snake that previously had eaten a frog and the frog ate a grasshopper and so on. But this tells us very little. A foodweb will tell us how all those animals are connected and what they eat in a web, not just a line.
Answer:
CO2 is a nonpolar molecule that can diffuse through the plasma membrane. As long as it diffuses away so that the concentration remains low outside the cell, it will continue to exit the cell in this way.
Explanation:
Tissues
Cells when grouped form tissues, when group of tissues are formed together they make organs, some organisms skip from organs to organs systems to form an existing organism as a whole<span>. Describing how is the cells group </span>is the process of multiplication of cell or the so-called cell division, mitosis.<span> This mechanism of each cell produces another cell that binds together and produces again, repeatedly, to be a larger system called now the tissue as explained earlier. </span>
The equation for the thermal efficiency of a system is given by n = Tc/Thx100
where n is the thermal efficiency, Tc is the temperature of the cold reservoir
and Th is the temperature of the hot reservoir. Dividing 190 by 515 gives us an
efficiency of 36.9%.
The U.S. has one of the highest, if not, the highest obesity rate in the world.
