Answer:
Like bees and other pollinators, butterflies pick up pollen while they sip a flower's nectar. Once they're off to another plant, the pollen goes with them, helping to pollinate the plant species.
Explanation:
The guard cell is responsible for controlling the size of the stomata in leaves. These do so as a result of an interaction between potassium ions and water in and around the cells. When potassium ions accumulate inside the guard cells the water potential inside these cells is lower than that of the outside and as a result, water has to be taken in. This makes the guard cells turgid which in turn stretches them and results in the opening of the stomata. Meanwhile, when potassium ions accumulate outside the cell, the opposite scenario results. Water from inside the cell moves out, making the guard cells flaccid, thus causing these to cover (and effectively close) the stomata.

Answer and Explanation:
In crickets, femur length represents a highly important trait associated with jumping performance - an essential behavior for their survival and reproduction.
According to research, these are the possible advantages and disadvantages in regard to long femur length:
Advantages
- Longer legs [may] provide higher power for the muscles in order to jump.
- Long-legged crickets generate lower reaction forces while performing a jump, which enables them to lose less energy in comparison with crickets with shorter femur length.
Disadvantages
- Longer femurs may increase the total take-off time of a cricken prior to a jump.
- In some cases, longer femurs force insects to develop head or body structures to enable them to 'fit' the legs while they prepare to jump.
- Increased energy loss while jumping from an elevated leaf.
