An observation may generate a scientific question, which may lead to a hypothesis. The hypothesis can be tested the experimentation. The results of experimentation lead to changes in scientific knowledge.
The benefits of stem cell research are associated with the development of specialized cell lines.
<h3>What are stem cells?</h3>
Stem cells are pluripotent cells that can be used to develop virtually any type of specialized cellular type.
These cells (stem cells) have the ability to self-renew and thus generate germinal layers present in an embryo.
Stem cells are used in research to investigate how certain gene expression patterns determine the formation of certain cellular types.

There are three types of proteins; fibrous, membrane and globular. Globular proteins are soluble in water and it usually round or spherical in shape. These proteins are from compacted amino acids which folds to its shape or form. They act as enzymes, biological messengers and transport mechanisms.
The answer would be the first option. A four-year degree in biology,
physics, microbiology, medical technology, chemistry, or genetics, is obligatory
permitted to get an entry-level job in forensic science. Taking lessons in law
and communication can also be useful. Furthermore, experience in a laboratory
may be obligatory by some crime labs.
