Answer:
The commensal relationship between the sharks and remoras can be described as although remoras consume parasites, sharks with remoras show no better health or growth than sharks without remoras.
Explanation:
A commensal relationship refers to a relationship where two or more organisms in a habitat neither benefit or harm each other.
- The second option infers that the remoras harm the sharks. This is a parasitic relationship.
- The third option infers that the sharks are harmed by the remoras because the sharks depend on something that the remoras are limiting. This is also a parasitic relationship.
- The fourth option infers a commensal relationship, but falsely describes it. The relationship described by this option is a parasitic relationship (one benefits, the other does not).
Therefore, the answer is the first option: Although remoras consume parasites, sharks with remoras show no better health or growth than sharks without remoras.
Because humans are omnivorous thus they can feed on different organisms. They can never occupy the lowest levels because they are not omnivorous.
Answer:
Starch degrading enzymes like amylolytic enzymes are generally significant in the industries to deal with biotechnology, with immense applications in food, textiles, fermentation, and paper. Bacteria produce amylase chemicals including utilizing Bacillus sp., a naturally found polymer, for example, starch, proteins, gelatin
starch degrading microbes in pure culture from soil utilizing a starch loaded agar medium, The two bacterial strains Bacillus amyloliquefaciens and Bacillus licheniformis and cow manure are some of example
Answer:
The correct answer is option d. "Many species that moved into North America from South America outcompeted the endemic taxa and still exist today".
Explanation:
The Great American Biotic Interchange (GABI) was an historical period at which numerous species from South America migrated to North America, and numerous species from North America migrated to South America because of the formation of the Isthmus of Panama. During this event, many species that moved into North America from South America outcompeted the endemic taxa and still exist today. The species that successfully immigrated to South America and exist today were mostly small mammals, such as armadillos and opossums.
