The answer is invasive species.
Invasive species are species that are not native to specific ecosystem,
but they have a capability to spread widely through the ecosystem, This way
they can threaten native species of the ecosystem or cause
environmental harm.
<span>After being introduced into the Black Sea, they greatly affect local
ecosystem. In the new area, they have no natural predators and are able to
spread. If they spread beyond the area they are introduced, they
become invasive species which can overgrow native biotopes and are
a great threat to the local biodiversity. This could lead to the extinction
of some native species.</span>
DNA analysis helps scientists classify similar animals by the evidence of relatedness in general the more derived genetic characters to organisms share the more closely repeated they are...In other words “DNA helps scientists by comparing the similarities in each animal/person’s DNA.
Answer:The ratio of the concentrations of
and
when the buffer has a pH of 7.02 is 0.69
Explanation:
The dissociation constant for formic acid =
Concentration of HA= 0.5 mM
Concentration of
= 0.1 mM
pH = 6.16
First we have to calculate the value of
.
Using Henderson Hesselbach equation :
Now put all the given values in this expression, we get:
To calculate the ratio of the concentrations of
and
when the buffer has a pH of 7.02.
Using Henderson Hesselbach equation :
Thus the ratio of the concentrations of
and
when the buffer has a pH of 7.02 is 0.69
