A bicycle factory installs about 400 tires per day. Tires are installed Monday through Friday for 8 hours per day. The manager of the factory estimates the number of properly installed tires per week using the process below. In the first hour of work on Monday, 49 out of 50 tires were properly installed. So, there were about 8(49) = 392 properly installed tires on Monday. Considering 5 working days per week, 5(392) = 1,960 is the number of tires properly installed in one week. Which best explains the validity of the results?The results are likely invalid because it is unlikely that the tires installed in one hour on Monday will represent the entire population of tires. The results are likely invalid because the entire population during one week was not part of the sample. The results are likely valid because a large number of tires produced during the week were part of the sample. The results are likely valid because each tire sampled was part of the population of tires that week.

this is true, assuming that the allele is completely recessive and incomplete dominance is not a factor.

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.
