Answer: C
Explanation:
When breeders notice a unique trait of interest and selectively breed to increase their population, there is tendency of also increasing the population of lethal genes. This happens via a situation known as inbreeding depression. There is a tendency to mate closely related individuals in a bid to increase the occurrence of a desired phenotype. However, in a situation where these animals have a recessive lethal gene, it may result in a double recessive thus becoming obvious in the population.
Answer:
Decreasing the consumption of water helps to maintain the fresh waters of our planet, the less we consume the less quickly they will end.
If we abuse fresh water, one day the planet will end and the salt water from the seas will have to be filtered, which is much more expensive and more polluting.
Explanation:
In addition, we must bear in mind that the less we use the water, the less we will contaminate it with chemicals such as shampoos, rinse creams, soap, therefore less water will end up in the non-recyclable water cycle.
All the water we use will end up being polluted and will not enter the natural cycle of water from river rainfall, irrigation and evaporation in the skies.
