Describe a hypothetical scenario of founder effect for a trait where substantial genetic variation is lost (causing a genetic bottleneck). Be sure to describe each of the key elements (such as why the founder event occurs, why genetic information is lost, and how the trait frequency changes over multiple generations).

After reading the paragraph below, answer the questions that follow. researchers have created a robot that has a very thin leg that is moved by cardiac (heart) cells contracting in unison. the robot, made of a polymer similar to that used in making contact lenses, is bathed in heart cells with supporting cells, which then attach to the robot and provide movement as they contract. all of the cardiac cells working together can cause the robot leg to move in a way that individual cells could not. this is an example of a. emergent properties of cells. b. energy flow through an ecosystem. c. adaptation. d. internal environment regulation.

How can scientists test their ideas about the origin of the universe if they can't physically interact with or study?
