Answer:
Fracking has adverse effect on water resources. The most potent danger lies in the fact that the fracking fluid may flow back to the surface and contaminate water.The fracking fluid contains toxins and carcinogen along with sand. This fluid when mixes with fresh water resources by any chance will prove hazardous. And hence degrade the availability and quality of potable water.
Explanation:
- Fracking or hydraulic fracturing is a technique used by industries to bring out oil and gas from the rock reservoirs.
- In this process a fluid known as fracking fluid is forcefully injected into the rock so that a fissure can be created and the rock breaks open due to the extreme pressure of the fluid.
- Fracking fluid can prove itself to be a environmental Hazard , because of the toxic chemicals and carcinogens mixed in it.
Answer:
Option B
Explanation:
The mode of speciation exhibited by these mice might follow the allopatric or peripatric pattern in that since these mice are in some ways related as stated, it is possible species C has become isolated from a peripheral population (in this case a peripatric speciation) due to maybe some geographical changes (allopatric speciation in general) as seen in vegetation changes at each elevation level and also no gene flow occurs between these population. And this depends on the number of individuals that dispersed from the original population. If large, it might be mainly by genetic drift.
Because of the fronts that are hot and moist. (Maritime tropical)
Answer:
A deviated septum occurs when bone and the cartilage that divides the nose septum become off-center which results in two unequal nasal septum. This makes one nasal chamber smaller and another larger.
This abnormality causes difficulty in breathing because of the congestion and blockage of the smaller nasal cavity. Due to this congestion airflow in the lungs is hindered which results in lack of oxygen and difficulty in breathing.
Apart from difficulty in breathing it can leads to nose bleeding, loud snoring during sleep, facial pain, headache, and in respiratory infections breathing become more difficult.
A deviated septum can develop due to some trauma or during surgery but some people are born with this abnormality.
