Answer:
250 years
Explanation:
The Atlantic Ocean is not static, but instead it is very active, and it is actually spreading from its central part. In its central part, this ocean has a mid-ocean ridge. This basically means that there is constant formation of new crust from the magma that comes out, and the old crust is pushed sideways as the new one is formed. On an annual level, the mid-ocean ridge is spreading out by an estimated 0.02 meters, thus that is how much the Atlantic Ocean is spreading out each year. In order to get to the result as to how many years are needed for the Atlantic Ocean to spread 500 cm, we just need to multiply the annual spreading with the number of cm in question:
0.02 x 500 =250
Thus we get a result of 250, meaning that in 250 years the Atlantic Ocean will spread out 500 cm in total.
Answer:
How have phosphate minerals most affected human activity? Using phosphate minerals in fertilizer allowed humans to grow more crops. The availability of rock and mineral resources has major effects on human activity.

Answer:
It's true, almost every body has the same cells of DNA.
Answer:
The correct answer would be - complex eyes evolved in the gradual steps, each of which was fully functional and adaptive in improving visual acuity.
Explanation:
The natural selection of the complex traits such as the vertebrate eye (complex eye) are seems to be problematic, many biologist think that the complex eyes evolution is take place in gradual steps and each step of this evolution was adaptive and functional in improving the visual acuity.
The steps that were involved are like light sensitivity patch, a deepening hole or pit that help in sharp vision and many other random evolution steps.
Thus, the correct answer is- complex eyes evolved in the gradual steps, each step of this evolution was fully functional and adaptive that helps in improving visual acuity.
