In pea plants the allele for round seeds (r) is dominant and the allele for wrinkled seeds (r) is recessive. under what conditions would we observe wrinkled seeds in a pea plant? when the plant has a genotype rr when the plant inherits a dominant allele from both parents when the plant inherits a recessive allele from both parents when a plant has a heterozygous allelic pair of the gene for seed shape

im positive its the third one, im doing the test right now and it common sense that if the parents BOTH have a recessive allele, the offspring would too.

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.
