The main advantage that allowed gymnosperms (the conifers) to evolve from filicinophyta (the ferns) is shedding snow in hilly regions.
How did gymnosperm get evolve?
- Fossil records demonstrate the primary gymnosperms (progymnosperms) in all likelihood started in the Paleozoic time, during the center Devonian time frame around quite a while back.
- Following the wet Mississippian and Pennsylvanian periods, which were overwhelmed by goliath plant trees, the Permian time frame was dry.
- This gave a conceptive edge to seed plants, which are better adjusted to endure droughts.
- The Ginkgoales, a gathering of gymnosperms with only one enduring animal variety, the Gingko Biloba, were the principal gymnosperms to show up during the lower Jurassic.
- The fundamental benefit that permitted gymnosperms (the conifers) to advance from filicinophyta (the plants) is shedding snow in sloping areas.

Explanation:
To calculate the pH of an aqueous solution you need to know the concentration of the hydronium ion in moles per liter (molarity). The pH is then calculated using the expression: pH = - log [H3O+].
At the very top of the swing the velocity=0. If the velocity is 0 then the kinetic energy is 0 as well because kinetic energy is the energy of movement.
