A plant has a unique photosynthetic pigment, causing the leaves of it to appear reddish-yellow. What wavelengths of visible light are being absorbed by this pigment

blue-violet

Explanation:

Generally the appearance of a photosynthetic plants depends on the wave of light on the absorption spectrum that the pigments absorbs.  Thus a leaf appears green at  sight  because the  chlorophyll pigment  absorbed  wavelength of lights in red-blue-violet region, and reflect green back to the eyes.

Carotenoids appears as orange-yellow in color to eyes.Thus the plant in the question is a carotenoids. They usually absorbed light in blue-violet region of absorption spectrum. Therefore since this plant  is a carotenoids, definitely it must absorbed in Blue-violet ,(400-550mn) and appear orange-yellow since it did not absorbed this but reflects  back to eyes.

c. earths continental crust is thicker than its lithosphere.

because, the lithosphere is the outermost layer of the earth/ 100 km thick and is defined by its machanical properties.the lithosphere contains oceanic and continental crust that varies in age and thickness across locations and geologic time. the lithosphere is the coolest layer of the earth in terms of temperature. the term lithosphere should not be confused with the use of "geosphere" which is used to indicate all of earth systems, including the atmosphere, hydrosphere   and biosphere. the surface of the earth can be divided into the continental crust and the oceanic crust.   the continental crust is made mostly of granite while the oceanic crust is made of basalt. the average thickness of the continental crust is 25 miles and the average thickness of the oceanic crust is 5 miles.   three types of rock, igneous, sedimentary, and metamorphic, make up the surface of the earth. that's why 3 option is preferable.

she will be charged $6

step-by-step explanation:

48 dollars divided by 200 beads equals .24 dollars a bead

.24 multiplied by 25 more beads equals 6 dollars as the total cost
