Cane toads are native to Central and South America and to Mexico. In the 1930s, people brought cane toads to Florida and Australia to consume beetles that cause damage to sugar crops. While the cane toads have been successful at reducing beetle populations, they have also had unforeseen impacts as well, such as being toxic to local predators.
A community in Florida wants to minimize the impact that cane toads have on the local ecosystem. Which of the following should they identify as part of defining the problem?
A.
ways to raise money to support their efforts
B.
the predator populations that eat cane toads
C.
methods that have been used to control cane toads in Australia
D.
solutions that are likely to be effective for controlling the cane toad population

The content of manganese (mn) in steel was determined spectrophotometrically and with the use of the standard addition method. an unknown sample of mn from a digested steel sample gave an absorbance of 0.185 when analyzed spectrophotometrically. when 5.00 ml of solution containing 95.5 ppm mn was added to 50.0 ml of the unknown steel solution (digested sample), the absorbance was 0.248. calculate the concentration, in parts-per-million (ppm), of mn in the digested steel sample solution.

Imagine that a new planet is discovered with two moons of equal mass: moon a and moon b. the mass of the new planet is greater than the combined mass of its moons. moon a is farther away from the new planet than moon b. what is the planet's gravitational pull on moon a compared to the planet's gravitational pull on moon b? the planet's gravity repels moon a with a greater force than it repels moon b, which is why moon a is farther away. the gravitational pull on moon b is greater than on moon a because moon b is closer to the new planet than moon a. the gravitational pull on moon b is greater than on moon a because moon b is farther away from the new planet than moon a. the gravitational pull on moon a is the same as the gravitational pull on moon b because distance does not affect the planet's gravity.
