Final answer:
Cacti and kangaroo rats are most likely to be found in deserts due to their adaptations to arid conditions.
Step-by-step explanation:
Cacti and kangaroo rats are most likely to be found in a desert. Deserts are characterized by their arid and dry conditions, with little rainfall and extreme temperatures. Cacti have adaptations such as thick, fleshy stems and spines to store water and protect themselves from herbivores. Kangaroo rats have efficient kidneys that help them conserve water by producing concentrated urine. They are able to obtain all the necessary moisture from their food, which consists mainly of seeds.
