Answer:
An earthquake is caused by a sudden slip on a fault. The tectonic plates are always slowly moving, but they get stuck at their edges due to friction. When the stress on the edge overcomes the friction, there is an earthquake that releases energy in waves that travel through the earth's crust and cause the shaking that we feel.
In California there are two plates - the Pacific Plate and the North American Plate. The Pacific Plate consists of most of the Pacific Ocean floor and the California Coast line. The North American Plate comprises most the North American Continent and parts of the Atlantic Ocean floor. The primary boundary between these two plates is the San Andreas Fault. The San Andreas Fault is more than 650 miles long and extends to depths of at least 10 miles. Many other smaller faults like the Hayward (Northern California) and the San Jacinto (Southern California) branch from and join the San Andreas Fault Zone.
The Pacific Plate grinds northwestward past the North American Plate at a rate of about two inches per year. Parts of the San Andreas Fault system adapt to this movement by constant "creep" resulting in many tiny shocks and a few moderate earth tremors. In other areas where creep is NOT constant, strain can build up for hundreds of years, producing great earthquakes when it finally releases.
B. the building of dams.
C. a slow recharge rate.
D. infiltration by acidic water.
Answer: Option A) sinkhole formation.
Explanation:
A sinkhole refers to any dug-out or depressed area of land where human
or animal waste (excreta) are deposited.
Now, since these wastes contains water and are biodegradable by microorganisms, the fecal matter could be infected and in turns infect groundwater.
The contaminated-groundwater poses danger due to disease-causing organisms like
- vibrio cholerae, causing cholera
- Salmonella typhi, causing typhoid outbreak present, and also reduces volume of suitable drinking water in the community
Thus, the answer is sinkhole formation
In aerobic respiration, the final electron acceptor in the electron transport chain is oxygen. It accepts two electrons and a molecule of water is formed as a by product.
In anaerobic respiration, the final electron acceptor in the electron transport chain is pyruvate. Anaerobic respiration commonly occurs in the muscle tissue of animals as a result of intense activity or exertion. Pyruvate is used as makeshift electron acceptor in place of oxygen and is reduced or converted to lactic acid.
In the electron transport chain involved in aerobic respiration, oxygen plays the essential role of final electron acceptor. It receives low-energy electrons and forms water, allowing the process to continue and ATP to be produced. This chain also allows for the creation of various other biochemical molecules.
The final electron acceptor in the electron transport chain, which is a part of aerobic respiration, is oxygen. As electrons are passed down the electron transport chain, from NADH or FADH₂, they lose energy. This journey through a series of redox reactions creates an electrochemical gradient used in chemiosmosis, contributing to the production of ATP.
Oxygen is the final receiver of these low-energy electrons. In combination with hydrogen ions, it forms water, which is one of the end products of the electron transport chain. Consequently, the presence of oxygen is crucial for the functioning of the electron transport chain and the production of ATP, our body's primary energy currency.
ATP generation is only one of the many functions of the electron transport chain. Other biochemical molecules, such as nonessential amino acids, sugars and lipids, can also be produced from intermediate compounds of glucose catabolism. These molecules, in turn, can serve as energy sources for glucose pathways.
