of 
and maintains a fairly constant . Â 
is given as follows:
and 
, then on adding 
the concentration of 
increases by this amount while the concentration of ![\begin{aligned}\left[ {{\text{HA}}} \right] &= 0.10{\text{ mol}} - 0.020{\text{ mol}}\\&= {\text{0}}{\text{.08 mol}}\\\end{aligned}](/tpl/images/0131/6741/3b92b.png)
 ![\dfrac{{\left[ {{{\text{A}}^- }}\right]}}{{\left[{{\text{HA}}} \right]}}](/tpl/images/0131/6741/a77cc.png)
is calculated as follows:
![\begin{aligned}\frac{{\left[ {{{\text{A}}^ - }} \right]}}{{\left[ {{\text{HA}}} \right]}} &= \frac{{0.22}}{{0.08}}\\&= 2.75\\\end{aligned}](/tpl/images/0131/6741/39ad3.png)
![\dfrac{{\left[ {{{\text{A}}^ - }} \right]}}{{\left[ {{\text{HA}}} \right]}}](/tpl/images/0131/6741/c9de0.png)
is 2.75. Hence as there is no appreciable fall in this ratio so the buffer capacity is not exceeded upon addition of

Many bird species build nests in which they raise their offspring. one of these species is known as the magnolia warbler. breeding pairs of magnolia warblers build nests out of pieces of grass and twigs. the female warbler will then lay her eggs in the nest and sit on the eggs for a few weeks until they hatch. after the offspring have hatched, the female will continue to sit on the newborn chicks to keep them warm. both the male and the female bring food for the offspring to eat until the young are mature enough to find food on their own. which of these most likely describes why birds such as the magnolia warbler build nests in which to raise their offspring? a. nest building decreases the amount of energy used by the parent birds to raise their offspring to adulthood. b. nest building increases the probability that the offspring will survive and eventually produce offspring of their own. c. nest building decreases the amount of food that the offspring require the adult birds to provide. d. nest building increases the probability of the offspring being located by airborne predators.
