A student runs a simulation of resource consumption in which cereal is used to model a resource. the student spends 15 seconds u
sing 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
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.
Birds and butterflies don't have a common ancestor because one is a member of a insect and the other is well a bird. They both have different body structure. One has bones and the other has an exoskeleton. hope this helps
Glucose particles are ingested from gastrointestinal cells into the circulatory system. The circulation system then, at that point, conveys the glucose particles all through the body. Glucose enters every cell of the body and is involved by the cells mitochondrion as fuel.
Light microscopes can only magnify up to 2000 times the original size. It is difficult to enhance the contrast between cells and their surroundings to see cell structure and movement with a light microscope.
Explanation: Scientists are able to understand Earth's interior by studying seismic waves. ... Seismic waves travel at different speeds when they pass through different types of material, so by studying seismograms, scientists can learn a lot about Earth's internal structure.
