The mass number of an element is equivalent to the number of Protons and Neutrons in the element. For example Oxygen has eight protons and neutrons, therefore its mass number is 16. You could also calculate this by simply rounding the atomic weight of the element to the nearest whole number. Oxygen's atomic weight is 15.994, which as you can see, would be rounded to 16 :)
Answer:
Deposition is both constructive and destructive.
Explanation:
Constructive forces include volcanic eruption.
Destructive forces include weathering and erosion.
Answer:
The answer is C. Sympatric Speciation via polyploidy
Explanation:
Among all various forms of speciation that exist, the most rapid is sympatric speciation which occurs when a population becomes separated in terms of reproductivity. The process of offsprings developing with more than the common number of chromosomes is referred to as sympatric speciation via polyploidy and it is this process that makes this speciation rapid.
