The functions of the cell are generally thought to determine the upper and lower limits of cell size. The determination of cell size has been a matter of inquiry by scientists for a century or more.
The cells must be large enough to include all of the necessary structures and materials, including DNA, ribosomes, enzymes and other cellular structures, determining the lower end of the scale. On the upper end of the scale, it must not be so large that it can no longer control the enzymatic and cell division processes that are essential to its functioning.
An individual cell must also be the right size to fit into whatever larger structure or substance it may be a part of as well as the environment in which it exists. Some experimental evidence suggests that the cell itself is aware of its size and can regulate it to time cell division.Learn More
The function of political science is to strive to create an ideal government through the study of and application of theories about and observations about government. The importance of political science is that, without it, world governments would be stagnate and government systems would never improve. This is crucial because governments are central to civilization. Without them, mankind would regress.Full Answer >
In a science project, the data analysis process occurs after a person performs an experiment to determine whether the hypothesis, an educated guess, is true or false. Analyzing the data consists of reviewing, calculating and charting the results of the experiment.Full Answer >
The organelle that manages cell functions in a eukaryotic cell is the nucleus. Most eukaryotic cells have a single nucleus; however, some organisms may have several nuclei per cell.Full Answer >
To make paper airplanes for a science project, paper of varying thicknesses should be used to determine which is the most effective. These might include copy paper, construction paper or other heavier paper, as well as paper clips for experimenting with weights. The basic model is made by folding copy paper. Variations on the design are then created and the flight results recorded so that they can be compared with the original.Full Answer >
