Answer:
Explanation:
Building and business closures for weeks or months reduce water usage, potentially leading to stagnant
water inside building plumbing. This water can become unsafe to drink or otherwise use for domestic or
commercial purposes. For example, optimal growth conditions for undesirable pathogens, such as
Legionella bacteria, can occur when hot water temperatures decrease and disinfectant residuals (e.g.,
chlorine) drop to low levels. Water chemistry changes may also increase corrosion and leaching of
metals, including lead, and may cause the formation of disinfection by-products. Turning on the water
for immediate use after it has been stagnant can pose a risk to public health if not properly managed.
Additionally, turning on water after a prolonged period of non-use could disrupt pipe and plumbing
scales to such an extent that microbial and chemical contaminants could be released into the water.
EPA recommends that building owners and manage
Answer: After the hurricane, Galveston raised the elevation of many new buildings by more than 10 feet (3 meters). The city also built an extensive seawall to act as a buffer against future storms. Despite the reconstruction, the city's status as the premier shipping port was lost to Houston a few years after the disaster. Ike, however, is projected to head west on a path that will take it close to Hispaniola, Cuba, and the Florida Straits.”
Explanation:
The quartz is more resistant to abrasion and chemically more resistant than the feldspar. The result is that the quartz remains in the stream but the feldspar breaks down to clay or is dissolved.

Answer:
The true statement is - Sympatric speciation only occurs in areas where there is local variation in environmental resources
Explanation:
- Sympatric speciation means the evolution of new species from an ancestor species which are occupying in the same area and no geographical barrier takes place.
- Overlapping of ranges takes place to the organism and old and new species are living i the same geographical region.
- A dam diving a fish population could lead to allopatric speciation where geographical barrier causes formation of new species which are completely different from their ancestor species.
