Explanation:
. Chemical digestion is the biochemical process in which macromolecules in food are changed into smaller molecules that can be absorbed into body fluids and transported to cells throughout the body. Substances in food that must be chemically digested include carbohydrates, proteins, lipids, and nucleic acids.
2.A fat molecule, such as a triglyceride, consists of two main components—glycerol and fatty acids. Glycerol is an organic compound with three carbon atoms, five hydrogen atoms, and three hydroxyl (–OH) groups.
3. If it's in the table, it's an element! Atoms can join together - they form bonds together - to make MOLECULES. For example, two atoms of hydrogen hook together to form a molecule of hydrogen, H2 for short.
4. When atoms join together to form molecules, they are held together by chemical bonds. These bonds form as a result of the sharing or exchange of electrons between the atoms. It is only the electrons in the outermost shell that ever get involved in bonding.
A compound is a molecule made of atoms from different elements. There are two main types of chemical bonds that hold atoms together: covalent and ionic/electrovalent bonds. Atoms that share electrons in a chemical bond have covalent bonds. An oxygen molecule (O2) is a good example of a molecule with a covalent bond.

This is worth 50 POINTS
Answer:
By reducing, reusing and recycling of non-renewable resources. Non-human species must be disturbed only to meet the basic needs. Planting of more and more trees to save our forest resources. Seeking alternatives to non-renewable resources.
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.
