C. How the organism is related to others 
Explanation:
From a single fossil, a scientist can learn how the organism is related to others. Fossils are the preserved remains of organisms that are usually found in rocks. 
- Organisms must posses certain characteristics to ensure their preservation as fossils. 
- Most organisms that are preserved usually have hard parts. 
- Some climatic influence can also arrest decay and provide a platform organisms to be preserved wholly. 
- Fossils are used for relative dating of events in nature. 
- They can also be used to determine how an organism is related to another. 
- This is called phylogeny. It is the study of evolution and how organisms relates to one another. 
- Fossils are very good and useful phylogenetic tools.

The appropriate answer is a. the conversion of radiant energy to chemical energy. Plants use light from the sun to convert carbon dioxide and water to glucose. An important bi-product of this reaction is oxygen which is vital to all life on earth. When humans consume glucose and do work they are converting chemical energy into heat energy and mechanical energy.
        
             
        
        
        
Answer:
D) Asexual reproduction produces offspring that are genetically identical to the parent.
Explanation:
I am honestly not quite sure of this answer, but I was trying to read up on the topic and this is the answer I'm most confident in. It would make sense that the offspring are genetically identical to the parent because they would have no where else to get their genes/mix to form new ones. I really hope this helps!
