<span>1. Mutualism is a type of relationship that can be seen between two individuals of two different speciesto 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>
-Are the Galapagos finches and those on the mainland the same species?
Explanation:
When Darwin visited the Galapagos islands he observed that the small flocks of finches that existed there were very similar to the finches that existed in the mainland of South America except for their beak shape and feeding habits.
This prompted him to ask the question that 'Are the Galapagos finches and mainland finches the same species?'
Later on studies made it evident that a few groups of mainland finches migrated to the Galapagos island and occupied different niches.
They adjusted themselves to the island environment and evolved with new adaptations in beak structure and feeding habits.
They are now classified into 14 groups out of which 13 exist in the Galapagos island.
The Galapagos finches are divided into three groups: the ground finches, tree finches and Warbler finches.
<span>Fast twitch muscle fiber is known to be most powerful and
lowest in endurance and usually
activated when the body is near maximum exertion. They are identified by a quick
contraction time and usually low resistance to fatigue </span>but are used in powerful bursts of movements like
sprinting. however, muscle fibers have the greatest capacity to produce energy via the anaerobic energy system.
