Answer:
The easiest way to monitor the usage is to manage the water flowing into the home. (If you have a slow flow in your home now, you have much more incentive to watch your use!) - Take baths that consume ten times less water instead of taking a bath.
Explanation:
Ways to save the water:
- Switch off the tap while your teeth are cleaned
- Insert your toilet cistern displacement unit to minimize the amount of water that is used with each flush
- Get a shorter tub. Short shower.
- Always use the laundry and dishwasher for maximum loads.
- Remove a drop tap.
- Build a drainage pipe with a water butt and water the plants
- Water the lawn instead of a pipe for watering.
Answer:
Anatomy. Species may share similar physical features because the feature was present in a common ancestor (homologous structures).
Molecular biology. DNA and the genetic code reflect the shared ancestry of life. DNA comparisons can show how related species are.
Biogeography. The global distribution of organisms and the unique features of island species reflect evolution and geological change.
Fossils. Fossils document the existence of now-extinct past species that are related to present-day species.
Direct observation. We can directly observe small-scale evolution in organisms with short lifecycles (e.g., pesticide-resistant insects).
