<span>1. Mutualism is a type of relationship that can be seen between two individuals of two different species to obtain benefits for both of individuals. 
Examples : Coral polyps and zooxanthellae
                   bee and flower
                   Lichens
                   Rhizobium and root nodules
                   Ungulates and bacteria which live in their intestines
</span><span>2. Commensalism (this is the correct word) is a type of relationship between two organisms which belonged to two different species that one individual obtains benefits while other doesn't have any harm or benefit.
Examples : Remora and sharks
                   Orchids and trees
                   Pseudoscorpions and Beetles
                   Cattle Egrets and Livestock
                   hermit crab and sea anemone
</span>
3. Parasitism is a relationship between two organisms of two different species where one individual (parasite) gets benefits by harming other individual (host). 
 
Examples : <em>Cuscuta</em> (parasite)<span> and angiosperms (host)
                    Parasitic viruses (parasite) and human (host)
                    Tape worms (parasite) and pigs (host)
                    Flukes (parasite) and human (host)
                    Parasitic bacteria (parasite) and human (host)</span>
        
             
        
        
        
<u>ANSWER:</u>
Scientific explanations are accepted when there is sufficient evidence to prove them right. In addition, scientific explanations must be logical to be acceptable and must match as much evidences as possible.
<u>EXPLANATION:</u>
- Scientific explanations explain something about the natural world by making use of observations and measurements. 
- These are usually tentative proposals that need to be verified or proved to be true. 
- The observations and measurements must prove the scientific explanation to be true or must support it so that it becomes acceptable.

There are some possible answers which all mean the same thing:
- Produce fertile offspring
- Produce offspring
- Reproduce
→ Only individuals of a same species (sometimes genus) can reproduce because in order to reproduce animals need to have a similar genetic code, and there is now code more similar than the one of individuals of their own species.
