Explanation:
One way for each farm to change its farming practices to avoid polluting the river with nitrates is through reducing the use of artificial fertilizers by using biofertilizers.
<h3 /><h3>What are biofertilizers?</h3>
They are organic fertilizers from materials easily found within a farm, such as manure compost, mineral salts and animal waste, which help to protect the soil, being a replenisher of soil organic matter and an advocate of agriculture.
Its benefits are directly linked to sustainability, since, unlike artificial fertilizers, biofertilizers do not contain nitrites, which are capable of generating pollution and ecological imbalance in rivers.
Therefore, biofertilizers are a relevant option for promoting sustainability, and such information should be more widespread in agribusiness, to promote practices that help to promote environmental responsibility and maintain the quality of life of current and future generations.

C) X=100%; Y=0%
B) X=50%; Y=50%
Explanation:
The oldest rocks on Earth are about four billion years old. When a rock forms, it contains unstable isotope and no daughter isotopes, so every rock will contain 100% parent isotope and 0% daughter isotope.
The half-life of the radioactive isotope Of this particular rock is 5730 years. The half-life is an amount of time needed for half of the parent isotope (50%) to become a daughter isotope. In this case, after 5730 years, half of the initial parent isotope will transform to daughter isotope, which means that after 5730 years, there will be 50-50 of the parent and daughter istotopes presented in the rock. After two half-lives, there will be only 25% of the parent isotope remaining (that’s half of the previous 50% which remained after first half-life), and after three half-lives, there will be only 12,5% of the parent isotope remaining and so on.
