Two moths with similar markings each produce a chemical that makes their bird predators sick to their stomach if eaten. Which principle of ecology does this dmeonstrate?

Wingardic acid is a madeup monoprotic acid that has a Ka of 1.9×10-7. Consider the titration of 48.00 mL of 0.350 M wingardic acid with 0.420 M NaOH. Note that the concentrations are not the same. Make sure sig figs are correct on your answers. Don’t round until the end. Show your work on your upload for full credit. As usual, work should follow examples as in lecture, showing BRA and/or ICE tables if appropriate and any assumptions you are making. You can use a generic HA for the acid formula. A.  The half equivalence point will be at ______ mL of titrant added and have a pH of ______? vol titrant = mL pH = B. The equivalence point will be at ______ mL of titrant added and have a pH of ______? vol titrant = mL pH = C.  What is the pH at the point when 44.5 mL of titrant are added? pH =                

Explain the difference between primary and secondary successions and give an example of each.

A 6.80 percent coupon bond with 14 years left to maturity is priced to offer a yield to maturity of 7.5 percent. You believe that in one year, the yield to maturity will be 7.1 percent. What is the change in price the bond will experience in dollars? (Do not round intermediate calculations. Round your final answer to 2 decimal places.)

 As a general rule, for each jump up in trophic level, about how much does the available energy drop?

CO2 makes up about ________ percent of the atmosphere.

_____is the process in which one presynaptic neuron suppresses another one

Nitrogen gas in the atmosphere is converted to forms of nitrogen usable by vegetation via:

An indicator H2Ind is diprotic with pKInd1=3.8 and pKInd2 = 7.4. The colors of the related species are: H2In is blue, HIn- is red and In2- is yellow. What color would you expect to see if this indicator is added to a solution with a concentration of of 4.0×10-8 M?

Part b. Considering your answer in the previous question, state whether a precipitate of MF3 will form or not and type your explanation answer here. No credit without a correct explanation.
