Astudent runs a simulation of resource consumption in which cereal is used to model a resource. the student spends 15 seconds using a fork and an index card to pick up pieces of cereal and transfer them to a cup. the student runs the simulation two times, keeping all factors the same except the amount of cereal that cant be picked up at one time. what variable is the student most likely testing? a. harvesting time b. population size c. rate of harvesting d. evenness of distribution

C. Rate of harvesting

The most appropriate answer would be c. the rate of harvesting.

The rate of harvesting would be best considered as an dependent variable of the experiment that is, it is the variable that is being tested in the experiment.

The student wants to set a relation between "time is taken to pick up cereal and transfer them to a cup" and "amount of cereal picked up at one time".

The rate of harvesting in this case depends upon the amount of cereals picked up at one time.

Thus, he or she wants to test the rate (number of cereals per unit time) at which cereals can be transferred to the cup.

The ansseer is Iridium.

The atomic number of iridium is 77 and it comes just before platinum (atomic number = 78).

In iridium,

The number of electrons = no. Of protons = 77.
The no. Of electrons and the no. Of protons is same as atomic number.
