If you are caught outdoors in a thunderstorm, why should you not stand under a tree? 1. a tree is likely to be hit by lightning
because it provides a path of less resistance between the cloud overhead and the ground. 2. a tree is likely to be hit by lightning because you and the tree now form a polarized system. 3. a tree attracts electrically polarized air molecules that can have a harmful effect on your body. 4. the tree has more resistance than the air and thus is likely to be hit by lightning. 5. a tree is likely to accumulate an electric charge that can kill you if you touch the tree.
The answer is 1. A tree is likely to be hit by lightning because it provides a path of less resistance between the ground and the cloud overhead. The ground and the tree are raised to a high potential relative to the ground that is further away. When you stand under a tree and it is hit by lightning, there is a high possibility that the lightning will hit you too
Based on the scenario being described within the question it can be said that two or more populations of toads will form that are genetically distinct from each other because the toads will eventually become isolated on each island. This is mainly due to one population beating out the other in each island and/or adapting the the unique features of the island.
