What process accomplishes the change from sporophyte to gametophyte?

Germination

Explanation:

The sporophyte reproduces asexually through spore formation. The spores are  formed in a capsule. Once the spores are mature the capsule breaks releasing them. The spores germinate to form a gametophyte. The gametophyte produces gametes that fertilize forming an embryo. The embryo develops into a sporophyte that remain attached to the gametophyte for nourishment.

the answer is; comparing the frequency of collisions with and without the device

this makes the anti-collision system an independent variable and the collisions a dependent variable. if there are fewer collisions with an anti-collision system that without, then it can be stated that the system is a success. essentially, collisions under an anti-collision system are compared with the frequency of collisions by cars with the human drivers.

hi~~

i would say that hybridization occurs frequently in nature, because there are many types of hybrids that have occurred naturally, such as the mule (male donkey + female horse)
