Dogs and cats are animals that have many similar body structures but they do not mate with each other. These two animals are classified in: the same kingdom and the same species; the same kingdom, but different species; different kingdoms, but the same species; or different kingdoms and different species?

Which two systems contain the heart and the stomach: endocrine and skeletal, endocrine and respiratory, circulatory and respiratory, or circulatory and digestive?
Circulatory and digestive
Which process is responsible for the growth and repair of human tissue: evolution, cell division, germination, or natural selection?
Three cats have differences with their fur length and patterns. These differences are most likely due to: dietary habits, sexual reproduction, habitat destruction, or damage from disease?
Sexual reproduction
The hereditary material in corn plants can be altered by scientists so the plants produce more corn. Which term identifies this process: environmental degradation, ecological succession, natural selection, or genetic engineering?
Genetic engineering
