Explain why the chemical released from the injured fish may not cause an alarm response in other fish species

Biology
1 answer:
Serggg [28]2 years ago
4 0
There is an evolutionary reason why such mechanisms would only work within species: Fish would get an advantage (as a population) from warning their co-specifics, but not from warning other species. So they would (through the process of evolution) tweak their signals to be only readable by the same species.

The concentration of pathogen needed to kill 50% of an infected group of test animals is the __________.
natulia [17]

Answer:

LD50 (median lethal dose)

Explanation:

  • Whenever one needs to quantify the virulence of a pathogen then this is done by using a set of laboratory animals.
  • LD50 (median lethal dose) is an important indicator of virulence. 
  • LD50 is defined as the number of pathogens that are required to kill 50% of the total infected animals.
  • For the calculation of LD50, the animals are infected with a known number of pathogens and then a graph is plotted for the percentage of animals killed against the concentration of the pathogen used for infection.<em> The point at which the graph indicates the death of 50% animals, the corresponding concentration of inoculation of a pathogen is taken as the LD50 of that particular pathogen. </em>
