False in a sense because it is not random. It is just that some organisms have more advantageous characteristics than others. These genes are then passed on which makes the likelihood of the next generation surviving greater.
The answer is D. at least im pretty sure...
The answer is 150,000,000 years (150 million years)
Let's first convert 7,500 km to cm:
1 km = 100,000 cm
7,500 km = 7,500 · 1 km = 7,500 · 100,000 cm = 750,000,000 cm
Now, it is known that the plate is spreading at 5 cm per 1 year. Make a proportion:
5 cm : 1 year = 750,000,000 cm : x
x = 750,000,000 cm · 1 year ÷ 5 cm = 150,000,000 years
