Answer:
Ecological Niche. The functional role of an organism or a species in the ecosystem, including its relationships with other species. ecology. The study of the distribution, abundance, and interrelationships of organisms and their interactions with the environment. Ecosystem
Explanation:
A Pseudopodia is a temporary protrusion of the surface of an amoeboid cell for movement and feeding.
The options are all related, and the answer is D) All of the Above.
The synergistic effects of exposure to multiple toxins are more difficult to quantify and study. As a result, there is not sufficient research on how much a system can take when exposed to multiple pollutants. This lack of research also means that we often do not even know what the effect of these interactions between multiple toxins are.
As a result of these gaps in our knowledge of the interactions between toxins, it is difficult to evaluate the threshold for pollutants, since a system will rarely feature only one pollutant in isolation.
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
