Answer:
Specialized structures such as 
1. The brightly colored flowers attract insects that transfer pollen from the anther to the stigma of another plant.
2. The scented smell of flowers and their nectars also attract insect and other pollinators to them.
Explanation:
Reproduction refers to the way by which plants and animals produce offspring or their types. Pollination, which is the transfer of pollen grains from the anther to the stigma of the same or another flower is a vital way by which plants accomplish this. 
Structures of plants such as their brightly colored flowers, the nectars produced by them, as well as their characteristic smells attract pollinators to them that, in turn, aid reproduction.

Answer:
The changing variables are: v and KE
Explanation:
Given

Required: What changes?
From the formula above:



m: The mass of the skater is constant.
v: Moving up and down the track may change the velocity of the skater. 
KE: When velocity changes, the kinetic energy also changes
So: 
The changing variables are: v and KE
