The neutral nature of water changes due to mixing of various salts, bases, and acids, thus changing its pH.
The neutral nature of water changes due to mixing of other neutral substances, thus changing its pH.
Answer:
Option B, The neutral nature of water changes due to mixing of various salts, bases, and acids, thus changing its pH.
Explanation:
Water obtained from natural sources like underground water, sea water, rain water etc are not neutral in nature. This is so because water extracted from all these sources contains several dissolved salts/chemical components which either reduces or increases their pH.
The ground water contains lot of dissolved carbonates and bicarbonates (as it remains in contact of rocks beneath the earth) due which it becomes extremely hard and has a pH greater than 7. On the other hand rain and snow water are acidic in nature and have a pH between 5 to 6.
Thus, it is only due to the dissolved bases and acids in natural water which makes it either acidic or basic in nature.

Free Space Path Loss
The Free Space Path Loss in a bridged network will be the source of the greatest loss in the transmission.
Explanation;
-Free-space path loss (FSPL) is the loss in signal strength of an electromagnetic wave that would result from a line-of-sight path through free space (usually air), with no obstacles nearby to cause reflection or diffraction.
-Free-space path loss is proportional to the square of the distance between the transmitter and receiver, and also proportional to the square of the frequency of the radio signal. This value is usually calculated by discounting any obstacles or reflections that might occur in its path.
The network bridge can be the source of the greatest loss in a network's transmission. It can cause delays due to processing times and data queueing. However, impacts are usually minute and can be mitigated with advanced technologies.
In a bridged network, the source of the greatest loss in transmission can generally be attributed to the network bridge itself. This is because the network bridge operates by receiving, processing, and forwarding data from one network segment to others. During this process, the bridge may produce delays, also known as latency. This latency is caused by factors like processing times and data queueing, which could potentially result in a loss in transmission.
The impact of this loss is usually minute and almost imperceptible in smaller networks but can become more significant as the size and complexity of the network increase. Bridging technologies have evolved significantly to mitigate this impact, for example, by using intelligent forwarding algorithms and advanced hardware capabilities.

When a factory is emitting large amounts of CFCs into the atmosphere, it affects the people in that area by the increase in the level of ocean water. CFCs dissolve in seawater and because they are not reactive, they just circulate until it becomes saturated.
A factory that is emitting large amounts of CFCs into the atmosphere might affect people by the increase in the rate of skin cancer.
Chlorofluorocarbons (CFCs) are substances carbon, chlorine, hydrogen and fluorine, which may harm the ozone layer.
In conclusion, a factory that is emitting large amounts of CFCs into the atmosphere might affect people by the increase in the rate of skin cancer.

Answer:
An increase in the number of invasive species leads to a decrease in the diversity index. This species can alter the food web within an ecosystem by eliminating the local food sources leaving no food for the faunas. If plant diversity declines, the habitat would definitely lose its balance. The ecosystem would lose its balance. Plants are considered producers and are always the beginning of the food chain. Without plants, animals that consume plants will definitely decline it number; thus, also the consumers on top of the chain.
