Reduces Flooding and Erosion. Harvesting rainwater can help the environment in a number of ways. ...
Reduces Water Bills. ...
Reduces Demand on Ground Water. ...
Can Be Used for Non-drinking Purposes. ...
Can Improve Plant Growth.
2.
Some advantages of tidal energy are: Environment-friendly. A highly predictable energy source. High energy density.
...
Some of the disadvantages of tidal energy are:
High tidal power plant construction costs.
Negative influence on marine life forms.
Location limits.
The variable intensity of sea waves.
3.
DNA replication is the process by which DNA makes a copy of itself during cell division. The first step in DNA replication is to 'unzip' the double helix structure of the DNA? molecule. ... The two separated strands will act as templates for making the new strands of DNA.
Explanation:
1. RAIN WATER HARVESTING.
Less cost.
Helps in reducing the water bill.
Decreases the demand for water.
Reduces the need for imported water.
Promotes both water and energy conservation.
Improves the quality and quantity of groundwater.
2. TIDAL ENERGY
ADVANTAGES
Environment-friendly.
High energy density.
Operational and maintenance costs are low.
An inexhaustible source of energy.
DISADVANTAGES
It is an intermittent energy source.
It should be close to land.
It is expensive.
It is not cost-effective.
3. DNA REPLICATION
DNA replication is the process by which DNA makes a copy of itself during cell division
