what structure controls most body functions and is refered to as the reptilian brain?
○ a. kidneys
○ b. heart
○ c. hypodermis

○ a. organ
○ b. organ system
○ c. rookery
○ d. tissue
○ e. lunula

Explanation:

• Matching Items: Endothermic animals (like mammals and birds) can regulate their body temperature internally. Ectothermic animals (such as reptiles and amphibians) rely on external sources for body - temperature regulation.
• Body Function Control: The hypothalamus is a key structure in the brain that controls many body functions and is sometimes referred to as the "reptilian brain" in some evolutionary - based terminology.
• Cell Grouping: A tissue is defined as two or more cells working together to perform a common function. An organ is made up of different tissues, and an organ system is a group of organs working together. A rookery is a colony of breeding animals (usually birds or seals), and a lunula is part of the nail.

Answer:

1. a. Endothermic
2. b. Ectothermic
3. d. Hypothalamus
4. d. tissue
