Which of these layers is found directly below the Earth's crust?

71% Answer Correctly

continents

outer core

The crust is the Earth's outermost layer and is divided into oceanic and continental types. Oceanic crust is 3 miles (5 km) to 6 miles (10 km) thick and is composed primarily of denser rock. Continental crust is 20 to 30 miles (30 to 50 km) thick and composed primarily of less dense rock. The crust makes up approximately one percent of the Earth's total volume.

In cell biology, cytokinesis results in two separate:

57% Answer Correctly

nuclei

5

Which of blood component carries oxygen?

83% Answer Correctly

red blood cells

white blood cells

platelets
