Meteorology is the study of the Earth's atmosphere and the variations in temperature and moisture patterns that produce different weather conditions. Some of the major subjects of study are such phenomena as precipitation (rain and snow), thunderstorms, tornadoes, and hurricanes and typhoons.
Nitrogen is an essential nutrient for plant growth. But farmers who cultivate pulse crops like green gram, bengal gram,black gram, etc. do not apply nitrogenous fertilizers during cultivation because of following reason
1. Leguminous plants like green gram, bengal gram,black gram contain nitrogen fixing RHIZOBIUM bacteria which convert nitrogen gas of air into nitrogen compounds which can be used by plants for their compounds
2. The nitrogen fixing Rhizohium bacteria live in the root nodules of leguminous plants.
Auricular Myiasis refers to fly larvae in the ear tissue. Myiasis is the inversion of body tissue of animal by the larvae of diptera or two winged flies. Myiasis parasitic infection by the fly larvae inside the while feeding on the tissue.
Answer:
The inactivation of one protein that slow down the cell cycle could lead to cancer. (option b).
Explanation:
The cell cycle is the process a cell undergoes when it divides during its life. This process includes a control mechanism to prevent normal cells from replicating more than normal, called cell cycle regulation.
In oncogenesis - the formation of malignant tumours - many factors induce the abnormal growth of a tissue by the abnormal multiplication of the cells that form it, leading to cancer. One of these factors may be a mutation in the DNA that prevents the production of regulatory proteins.
The mutation that produces exaggerated cell growth -and which can eventually lead to cancer- can create defects in a specific regulatory protein that slow down the cell cycle, so that exaggerated and uncontrolled cell replication occurs.
Once a tumor tissue has formed, successive mutations will lead to a lack of cell differentiation, the property of forming blood vessels, the ability to invade tissue and lose its apoptosis mechanism, that characterizes cancer cells.
