Explanation:
cost
- ongoing maintenance
- initial design and construction
benefit
- protection of infrastructure
- lower insurance costs
- employment opportunities
The flood mitigation projects have initial startup costs and ongoing maintenance costs over the years. However, apart from the costs, these have additional benefits like lower insurance costs due to protected infrastructure and reduced flood damage, along with employment opportunities during building and maintenance.
Further Explanation:
Flooding usually happens when lots of rainfall occurs in relatively short time periods. These are usually enough to cause rivers to overflow their banks and also occur when storms force large volumes of water from the ocean to travel inland. Typically these occur in arid ecosystems, having low average rainfall- the water accumulates in dry regions and saturates the area. This phenomena are majorly destructive and can uproot trees, destroy bridges, buildings and other infrastructure while leading to loss of life.

Correct answer: A. True
Explanation:
The dictionary definition of a "risk" is that someone or something of value is exposed to danger, harm, or loss (<em>Oxford Living Dictionaries)</em>.
Having said that, we should also note that without risk, there often is little or no reward. Sometimes taking a risk is necessary in order to achieve a gain. If I hide all my money under my mattress to avoid the risks associated with investing money in banks or the stock market, I don't gain any interest or growth on my dollars. If I won't get in a car or on an airplane because of the risks associated with automobile travel or air travel, I isolate myself and don't get to visit people and places beyond my immediate neighborhood.
Risk assessment and risk management will mean that we will assess the real risks of situations and activities, and balance those against potential rewards. We will take appropriate precautions and safeguards before taking a risk. For instance, if a child wants to learn how to ride a bike (which will bring the rewards of a fun and healthy activity), parents will make sure the child wears a helmet and possibly knee and elbow pads. They will start with training wheels or by going alongside to guide the bike before having the child attempt riding fully on their own.
Answer:
<em>Assimilation</em>
Explanation:
This is how plants get nitrogen. They absorb nitrates from the soil into their roots. Then the nitrogen gets used in amino acids, nucleic acids, and chlorophyll. ... When a plant or animal dies, decomposers like fungi and bacteria turn the nitrogen back into ammonium so it can reenter the nitrogen cycle.
Answer:
The ovum or egg cell is the part of female reproductive gamete present in oogamous organisms. The ovum is larger, and visible to the naked eye compare to motile sperm cell, and egg cell are not capable of active movement.
The cytoplasm of an unfertilized egg is contain unevenly distributed proteins, mRNA, other organelles, and substances. Many proteins are present in a concentrated form at the one end of the cell, and helping to provide positional information to the growing embryo.
