Answer:
By they way they work
Explanation:
For ex.
Meter ruler = meters
Measuring cylinder = liters
Measuring flask = liters
And so on

Answer:
1- Two tectonic plates separate as they are pulled apart by convection in the mantle.
2- Molten material from the mantle rises up towards the surface due to convection and fills in the rift.
3- New oceanic crust is formed.
4- The crust slowly moves away from the ridge equally on either side.
5- Overtime, the creation of oceanic crust will cause continents to move.
Explanation:
Oceanic plates get separated and the spaces left among them are filled with magma coming from the mantle. When the magma reaches the surface, it suffers physical and chemical changes at the moment it gets in touch with the cold ocean water. The magma temperature descends and turns into a new oceanic crust. Plates keep separating from each other, and the new oceanic crust moves forward each side of the crest making a place for the ascension of new fluid hot material from the mantle. This constant process is what makes the continents eventually get separated each time more.
Answer:
Postzygotic reproductive barriers
Explanation:
Post-zygotic reproductive barriers are the adaptations developed in the organism which occur after the zygote (fertilization product) has been formed.
The Post-zygotic barrier involves the hybrid inviability which refers to the reduction on the viability of the offspring and hybrid sterility or that is the production of the fertile reproductive barriers.
The production of mule by the mating of horse and donkey results in the infertile mule which is considered the mechanism of the post-zygotic barrier.
Thus, Postzygotic reproductive barriers are the correct answer.
