phosphorus, soil, water, oxygen
Explanation:
Phosphorus, soil, water and oxygen are renewable resources that can be found freely on earth.
Renewable resources are natural resources that can easily be replenished as they are used either by natural means or through cyclic processes in our human life time.
- Phosphorus, soil, water and oxygen are easily replenished by natural processes and through the biogeochemical cycle of materials.
- Fossil fuels, trees are not renewable as they can easily be depleted.
- Non-renewable resources must be used sustainably to ensure their all round availability.

The structure that they are showing is the general structure of an amino acid. If you look at the left side there's NH2 (an amino group). On the right side is COOH (a carboxylic acid group) and the R is the part that varies depending on the amino acid --this way you can make up the 20 different amino acids but all with the basic structure shown in the diagram.
Answer:
<em>The correct option is D) decreased ice causes less energy to be reflected</em>
Explanation:
Observations have shown that ice has the ability to absorb less solar radiation and reflect back most of it. On the other hand, liquid water absorbs more solar energy and reflects back a little of it.
Hence, the lesser the ice will be, the lesser will be the solar energy being reflected back. If the solar energy is not reflected back in adequate amounts it can cause global warming and the atmosphere of the Earth to be heated.
