The weight of an object is known to occur from the gravitational pull of the earth. Hence, for weight to occur, a certain force should be there. The more the gravitational pull the more the force.
According to this information, the planet made of iron will have high gravitational pull. Hence, the weight of an organism will be more on a planet made of iron rather than a planet made of cheese.
Cardiac Output. Cardiac Output (CO) is the amount of blood pumped by the heart per unit of time and it depends on 2 important variables like below, Stroke Volume (SV) = the amount of blood ejected per beat of the heart (Normally, 70 ml/beat).

Explanation: The concrete operational stage is the third stage in Piaget's theory of cognitive development. This period spans the time of middle childhood—it begins around age 7 and continues until approximately age 11—and is characterized by the development of logical thought. 1
Once the child reaches the Concrete Operational Stage, they can begin to separate and classify objects that are animate vs. objects that are inanimate. Children at the Concrete Operational Stage also have the ability to organize the items that they have classified. Seriation is the process is arranging items in a logical order.
