The variables are defined as the factors in an experiment, which are liable to change. The variable can be dependent or independent. The Independent variable is a variable, which is unaffected by the changes in the other variables.
In this case, the brand of the food Shara feeds to the rats is independent factor, but it is changes in the system, so, it is an independent variable.
The effect on the weight of the rat is dependent on the brand of food they are consuming. So, the weight of rats is dependent variable.
Intelligence is most likely to be the criteria for random mating in humans.
Explanation:
If random mating is taking place on the conditions that no evolution is taking place the genetic pool will be maintained through generations.
Random mating will be based on intelligence in humans because this is the trait which gets exhibited only when showcased otherwise remains hidden while other characters like personality, appearance and athleticism are phenotypically expressed character.
Random mating is not under the influence of genotype. Intelligence is a trait which needs to be more in human as random mating takes genotype frequency in consideration.
<u>Answer:</u>
Continuous pumping of water causes drawdown. The water table lowers rapidly.
<u>Explanation:</u>
- Water table is the level below which the ground is saturated with water.
- During rainfall the runoff water percolates into the ground through the gap in the soil particles and the water table is recharged.
- But when gallons of water are pumped continuously it leads to a drastic reduction in the water table because, water from the surrounding aquifers move towards the place where the vacuum is created by pumping.
- To prevent this, the groundwater should be recharged and over drawing should be avoided.
By conserving the residential water by recycling we can keep the fresh water as a renewable resource.
<u>Explanation:</u>
Preserving water is significant on the grounds that it keeps water unadulterated and clean while ensuring the earth. Private water use incorporates both indoor and outside family unit water utilization. Water is utilized inside for showering, flushing toilets, washing garments, washing dishes, drinking, and cooking.
Open air water use incorporates washing the vehicle and watering the grass, pools, and plants. This water alludes to the procedure which prepared the wastewater and changes over it to a reusable structure. Additionally gather water during the blustery season to use in latrine flush, watering plants, sprinkle in the nursery, and so on. Utilizing crude water like seawater or non-cleaned water in the latrine is likewise acceptable.
