Explanation:hope this helps..pls mark me brainliest
Natural resources are essential to sustain human life. These resources include air, water, soil, minerals, forests, and wildlife. However, the rapid population growth, industrialization, and urbanization have resulted in the depletion of natural resources. Therefore, it is imperative to protect them.
The following are some of the ways that can help in protecting natural resources:
1. Reduce, Reuse, and Recycle: Reducing the consumption of resources, reusing products, and recycling waste materials can significantly reduce the pressure on natural resources.
2. Conserve Water: Water is a precious resource, and its scarcity is becoming increasingly common. Conserving water by fixing leaks, using water-efficient appliances, and avoiding wastage can help protect this resource.
3. Promote Sustainable Agriculture: Sustainable agriculture practices can help in conserving soil, water, and biodiversity, which are essential natural resources for agriculture.
4. Use Renewable Energy: Fossil fuels are non-renewable resources that contribute to climate change. Therefore, it is important to use renewable energy sources such as solar, wind, and hydro energy to reduce the reliance on non-renewable resources.
5. Plant Trees: Trees help in purifying the air, conserving soil, and supporting wildlife. Planting trees can help in restoring the natural habitat and reducing the carbon footprint.
6. Use Public Transport: Using public transport, cycling, or walking can help in reducing air pollution and conserving fuel, which is a non-renewable resource.
In conclusion, protecting natural resources is vital for the survival of humanity and the planet. Implementing the above measures can help in reducing the pressure on natural resources and ensure their sustainability for future generations.

Every balanced chemical equation follows law of conservation of mass. This law states that mass can neither be created nor be destroyed but it ca only be transformed from one form to another form.
In a chemical reaction, total number of individual atoms on the reactant side must be equal to the total number of individual atoms on the product side.
During a chemical reaction, the atoms on the reactant side must also be present on the product side.
For the given reactants, the chemical equation will follows:
As, the reactant side contained carbon, hydrogen and oxygen atoms only. So, the product will also contain the same atoms.
the correct answer is Option B.

The structure of cordycepin reveals that it lacks the ___________. This functional group is critical for addition of _______________ to the growing RNA chain, so after cordycepin is incorporated as a ribonucleoside ___________into the RNA chain, it prevents the further addition of ________.
The structure of cordycepin reveals that it lacks the 3' OH. This functional group is critical for addition of [ribonucleotides] to the growing RNA chain, so after cordycepin is incorporated as a ribonucleoside [monophosphate] into the RNA chain, it prevents the further addition of [ribonucleotides].
What is the role of ribonucleotides in transcription?Ribonucleotide-based mutagenesis requires two Top1 cleavage events on the same DNA strand and, in the context of transcription, modifications arise mainly when the enzyme cleaves the not-transcribed strand of the reporter.
Thus, 3' OHribonucleotides, monophosphate are the answer.
