Skin is covered by epithelial cells. Liver is mainly made up of hepatocytes though fibrous and fatty tissues are also present.<span>Cells of skin epithelium are present in different layers. Lower most layer on basement membrane (all epithelia possess this barrier on which epithelial cells grow) are newly generated. These cells gradually acquire a protective protein keratin but loses vitality. Thus by the time cells reach top most layer of skin they are all dead cells.</span>

<h3>What are the steps in scientific research?</h3>
The steps in scientific research refer to the steps or procedures that are followed by scientists in making scientific discoveries that explain observed phenomena.
The steps in scientific research are as follows:
- Research question - this is the question that a scientist seeks to answer based on his/her observations
- Hypothesis - statements made by scientists to explain their observations
- Background research - research is done to find support for or against the hypothesis.
- Controlled experiment - tests carried out to disprove or prove the hypothesis
- Data collection
- Data analysis
- Conclusion

Answer:
Determination
Explanation:
Cell determination is one of the fundamental processes that result in the development of the form of an organism. Cell determination refers to a series of molecular events that alter the activities of certain genes in a particular way. These events finally make a cell to progressively commit to a particular differentiation pathway.
The events of cell determination may not cause any immediate changes in the structure and function of the cells but regulate them eventually. Once the cell determination events make a cell to differentiate in a particular way, the cell is specialized to carry out specific functions which means that its development fate is sealed.
