Answer:
The correct answer is D. 1/8
1 out of 8 is the probability of having three girls in a row.
Meiosis continually reshuffles the genes resulting in a great variety of offspring. Without meiosis we would all look exactly alike. Meiosis allows each offspring to be different, and so potentially better, than the parent. If a disease comes along, there is a good chance that some of the population won't get sick or die because everyone's DNA isn't exactly alike.
Appalachian: A. Two continents colliding.
The Appalachian mountain range is an ancient example of a collision between two continental plates. Both plates have low density and little subduction occurs between them.
North American Cordillera: B. Terrane accretion
These form when two continents that collided bonded so tight that it forms a permanent land mass. If the continents would pull away from each other, the terrane stays intact.
Aleutian plate: D. Oceanic convergence
This is a type of convergence where one plate subducts beneath another plate. Between the two, the older plate is usually the one that subducts because it is usually more dense.
Andes mountain range: C. An oceanic plate and continental plate colliding.
In the collision between an oceanic and continental plate, the thinner and more dense oceanic plate subducts under the continental plate. The Andes mountain range was formed by the subduction of the Nazca Plate beneath the South american Plate.
