Question:

There is a direct relationship that exists between surface area and heat loss in organisms. The larger the surface area, the greater the heat loss from the organism, and vice-versa. The organism is:

O It has an open circulatory system

O It has an exoskeleton

O All of these answers are likely true about this organism

O It excretes uric acid as its primary nitrogenous waste product

O It has the ability to fly

Body Temperature:

Body temperatures are gained or lost through conduction, convection, and radiation among organisms. Thus, constant body temperatures oversee biological and physical processes like; enzymes and cell membranes functionalities, regulate diffusion rates, and control blood viscosity.

Answer and Explanation: 1

There is a direct relationship that exists between surface area and heat loss in organisms. The larger the surface area, the greater the heat loss from the organism, and vice-versa. The organism is: O It excretes uric acid as its primary nitrogenous waste product

Ectotherms are organisms that control their body temperature based on their behaviors. Examples include reptiles like lizards.

However, endotherms internally maintain constant body temperatures through heat gain and heat loss. Thus, they require high energy levels to maintain basal metabolic rates. Examples include mammals and birds. Additionally, smaller endothermic animals, mice, lose heat fast compared to larger endothermic organisms, humans, due to their reduced surface area.

Thus, the primary characteristic of endothermic organisms includes having an excretion process that oversees the heat loss process. These occur through expelling urine and nitrogenous waste.

The Australian outback is a dangerous place filled with extreme temperatures. Today, we'll look at how different animals tackle the task of temperature regulation. We'll study two main classes: ectothermic and endothermic animals. You might be surprised by some of the unique ways animals regulate their temperature.
