The body structures for a population of chimpanzees were stable for a long time. Then, their body structures changed, making the chimpanzees stronger. Why did this happen?

• Organisms naturally become stronger over time.

• It is impossible to say without more information.

• The chimpanzee population wanted to be stronger.

• Their environment must have changed.

Which of the following best describes the concept of 'Evolution Amplify'?

• A process where evolutionary changes are accelerated in a population

• A method to slow down evolutionary changes

• A technique to reverse evolutionary changes

• A way to maintain the current state of evolution

In an experiment, scientists observed that a certain species of bacteria evolved to resist antibiotics much faster than expected. What could be a reason for this accelerated evolution?

• The bacteria were exposed to a high concentration of antibiotics

• The bacteria were kept in a stable environment

• The bacteria were isolated from other species

• The bacteria were given ample nutrients
