Which of the following describes the Earth's mantle?

55% Answer Correctly

liquid

solid

primarily liquid

primarily solid


Solution

Mantle makes up 84% of the Earth's volume and has an average thickness of approximately 1,800 miles (2,900 km). It is dense, hot, and primarily solid although in places it behaves more like a viscous fluid as the plates of the upper mantle and crust gradually "float" along its circumference.


5

Reproductive haploids are also known as:

63% Answer Correctly

sperm

diploids

ovum

gametes


Solution

Reproductive (haploid) cells known as gametes have half as many (23) pairs of chromosomes as normal (diploid) cells. When the male gamete (sperm) combines with the female gamete (ovum) through meiosis to form a zygote, each gamete supplies half the chromosomes needed to form the normal diploid cells.
