The vestigial structures in animals
for example we, humans once had a tail that is connected to our tail bone coccyx and every mammals you see had a tail.
The correct answer is C.Capsule i just finished a test on this
Answer:
1. Green beetles and red beetles exist in the environment.
2. Birds that eat the beetles move into the environment.
3. Red beetles are eaten by birds, but green beetles aren’t eaten.
4. Green beetles pass on their color trait to future offspring.
5. The entire population of beetles eventually becomes green in color.
Explanation:
According to the theory of natural selection, only those species survives which fits closely with their environment. According to the conditions given, there are two genetic variations of the same species based on the color, i.e. green and red. Initially, both red and green are living together in a grassland (green in color). Then, birds enter the same environment because they have food there (beetles). Now, green beetles will take a competitive advantage because of the color and avoid getting eaten by the birds. However, red beetles would be prominent and eaten fast. The green beetles will pass on their genetic variation causing the color to be green in their future offspring and a time will come when there will be on green beetles in the area.
The relationship between DNA bases and Genes, proteins, and traits. although you might have heard people talk about a gene for red hair, green eyes or other characteristics, it's important to remember that genes code for proteins, not traits
