<span>The correct answer is Mitochondria. That's why it is said that the mitochondria is the powerhouse of the cell. Cellular respiration is a process in which the mitochondria converts nutrients from food into energy created in the form of ATP and ADP. This energy is then transfered to wherever you need it to have a proper metabolism and keep your bodily functions normal.</span>

Answer:
A mutation in Ras protein which will cause hyperactivity will eventually lead to cancer.
Explanation:
Ras protein was first discovered in Rous sarcoma virus (RSV) and it is a proto-oncogene product. In normal conditions, it plays an important role in cellular signalling but in case of gain of function/hyperactivity it gets converted into cellular oncogene. In several types of cancers a point mutation has been reported in Ras protein.
Just like G protein, it is also a GTPase switch protein but unlike G protein which is trimeric, it is monomeric. In the plasma membrane, it is attached with the help of lipids like prenyl or palmitoyl groups. During signal transduction pathway when it gets activated, it downstream activates MAPK pathway and causes gene expression but when it gets hyperactivated it causes over expression of genes leading to cancer.
Abiotic factors determine which organisms can survive in an ecosystem because they are the non living objects in an ecosystem
