Explanation:
Accordingly, the introductory physics laboratories have the following purposes and goals:
1. To provide an experimental foundation for the theoretical concepts introduced in the lectures. It is important that students have an opportunity to verify some of the ideas for themselves.
2. To familiarize students with experimental apparatus, the scientific method, and methods of data analysis so that they will have some idea of the inductive process by which the ideas were originated. To teach how to make careful experimental observations and how to think about and draw conclusions from such data.
3. To introduce the methods used for estimating and dealing with experimental uncertainties, including simple ideas in probability theory and the distinctions between random (statistical) and systematic "errors." This is essential in understanding what valid conclusions can be deduced from experimental data and that, properly obtained, these conclusions are valid, notwithstanding the uncertainty of the data.
Hypothesis: Daphnias can increase in population at a room
temperature, rather than a colder or warmer temperature.
Control group will be at a room temperature water. The experimental will be tested in cold and warmer waters.
Independent variable: change of water temperature.
The data will be the amount of growth in which the water fleas population increases or decreases, a bar graph would work.
I THINK!!! a. but i could be wrong sry if i am
Yes, the story surprised me very much. However, I don’t think these similarities are something the twins inherited, I think they are coincidences. You can’t inherit the same wife or other similarity that are not decided by genes.
