Question

only one out of 1,000 sea turtles survives to adulthood. from the moment they hatch, sea turtles must strive for survival. they race across the beach and battle the waves moments after their birth. throughout this time, predators stalk them for an easy meal. some sea turtles are faster than others. which sea turtle do you think will be selected against? which trait is favorable? why? what are the variations in this population? how does this species overproduce? how will this species change over time?

Explanation:

1. Which sea - turtle will be selected against?

• Slower sea - turtles will be selected against because they are more likely to be caught by predators as they race across the beach and battle the waves.

1. Which trait is favorable? Why?

• Speed is a favorable trait. Faster sea - turtles have a higher chance of evading predators and reaching the safety of the ocean, increasing their survival rate.

1. What are the variations in this population?

• The main variation is speed. Some sea - turtles are faster than others, which affects their ability to avoid predators.

1. How does this species overproduce?

• A large number of sea - turtle eggs are laid (only 1 out of 1000 survives to adulthood), indicating that many more offspring are produced than can survive, which is a form of overproduction.

1. How will this species change over time?

• Over time, natural selection will favor faster - swimming sea - turtles. As a result, the average speed of the sea - turtle population may increase as slower individuals are less likely to survive and reproduce.

Answer:

1. Slower sea - turtles will be selected against.
2. Speed is a favorable trait because faster sea - turtles can better evade predators.
3. The variation is in speed; some are faster than others.
4. Many sea - turtle eggs are laid, with only a small fraction surviving to adulthood.
5. The average speed of the sea - turtle population may increase due to natural selection favoring faster individuals.
