What structure is common to all five kingdoms of living organisms?

Over many generations, unrelated or distantly related species may come to resemble each other due to — A similar environmental factors B similar genetic mutations C homologous structural adaptations D competition with each other

A student hypothesizes that thick leg muscles are an inherited trait in dogs. The student collects data on several dogs, and the data show that dogs that live outdoors have thicker leg muscles than dogs that live indoors. What should the student conclude? A Dogs that inherit thick leg muscles may not survive indoors. B Dogs with thick leg muscles may require more exercise than dogs with thin leg muscles. C Inheritance alone may not account for thick leg muscles in dogs. D Inheritance of thick leg muscles may be associated with coat thickness in dogs.

What is kind of structures are shown? Think about the appendix

A man treated his home with a pesticide that kills roaches A man treated his home with a pesticide that kills roaches. The first application of the pesticide killed 92% of the roaches. Two months later he applied the pesticide to his home again, but the second application killed only 65% of the roaches. What would best explain the decrease in the effectiveness of the pesticide?

One theory of the extinction of dinosaur species is that a large meteorite impact on Earth caused a major atmospheric change marked by colder temperatures. If this theory is correct, what adaptation of mammals probably allowed them to survive even though dinosaurs became extinct? A Superior low-light vision B Consumption of an omnivorous diet C Ability to bear live young D Endothermic body metabolism

Give an example of artificial selection.
