Answer & Explanation:
An organic molecule is one which contains carbon, although not all compounds that contain carbon are organic molecules. ... Although carbon is present in all organic compounds, other elements such as hydrogen (H), oxygen (O), nitrogen (N), sulfur (S) and phosphorus (P) are also common in these molecules.
The fraction will be positive . because negative and negative cancels
Answer:
None of the above.
Explanation:
GTPases are the regulatory proteins that are involved in the signal transduction pathway involving the activation of the G protein. The mutation in these proteins cal lead to cancer cells.
The guanine nucleotide exchange factors (GEF) allows the replacement of GDP by GTP. They activates the GTPase activity of the cell and can also activate the multiple GTPase activity of the cell. The Ras superfamily is activated by the GEF.
Thus, the correct answer is option (d).
Technology such as lenses, magnifying glasses, and microscopes had an impact on the development of the cell theory. Below are some examples of how such technologies contributed to the cell theory. Robert Hooke is accredited with observing the first cells in 1665. ... He used lenses to make the discovery.
