What are abiotic factors?
The definition of abiotic Is a non living part of the ecosystem that make up our environment for example Water and light!All of these factors work together to make up what we have today!
Why are they important?
They are important because with out these we would not be living because for example water is a abiotic factor and we can't live with out water!
Hope this helps!

the Cell Theory was give by German scientists, Schleiden and T.Shwan in 1839. It stated that,
- All organism are composed of one or more cells
- The cell is the structural and functional unit of life
- It is a de novo structure, that means it COULD arise from non living thing which was incorrect.
It was corrected by the German pathologist Rudolf Virchow in 1855. He made a convincing case, corrected and added the third point of the cell theory. It is,
- Cells can arise only by a division of pre-existing cell. It is <u>NOT</u> a de novo structure.
Cell theory brought a great evolution in the field of biology which established the function of organism is the result of activities and interaction of the cell units.

- <u>Flask 1</u>: It is observed that there are no micro-organism, this is because the meat is sealed and no micro-organism could enter through it.
- <u>Flask 2</u>: It is observed that there are micro-organism present because meat is not sealed but open.
- <u>Flask 3</u>: As the S tube is used, the micro-organism are not able to reach the meat because of the curvy path
These observations support the point that<u> cells could arise only by a division of pre-existing alive cells</u> because in Flask 1 when there were no micro-organism present so there was no organisms found so no micro-organism arised, In flask 3 the S tube was used so no micro-organism could reach the meat thus there were no organism there which could divide to reproduce. The flask 2 was open, so the micro organisms reached the meat so they divided which means Cells can only arise by a division of pre-existing cells.

Answer:
It is necessary to make the following assumptions when making inferences about a group of people based on a sample of subjects drawn from that group:
- Data is quantitative in nature.
- A sample size of 30 or more is required.
- The data set must consist of a simple random sample.
- A Normal Distribution must be present in the data.
The data must come from a sample that isn't all the same size so that it can be generalized well.
The sample size must be at least 30 or more, according to the central limit theorem.
Mean and standard deviation are two examples of quantitative data from which statistical conclusions can be drawn.
To avoid bias, the sample size should be increased rather than the distribution skewed.
