VERY EASY QUESTION. WILL MARK BRAINLIEST When two mechanical waves have a displacement in opposite directions, and they overlap, what will the resulting wave look like and why?

The new wave will have the same displacement as the original waves due to constructive interference.

The new wave will have a smaller displacement than either of the original waves due to destructive interference.

The new wave will have a greater displacement than either of the original waves due to constructive interference.

The new wave will have the same displacement as the original waves due to destructive interference.

Ry was studying two populations of the same species of lizards. one population lived on an island and the other lived on the mainland. both populations were affected by a hurricane that hit the island and the mainland with equal force. a year later, henry was testing the gene frequency and saw a decrease in genetic variation in the island species, but not in the mainland species. which best describes a conclusion he might have reached? gene flow greatly affects small populations, but large populations can recover. genetic drift greatly affects small populations, but large populations can recover. gene flow greatly affects large populations, but small populations can recover. genetic drift greatly affects large populations, but small populations can recover.
