Summary Introduction
To review:
The influence of body coverings of animals on its way of feeding, moving, and exchanging of gases.
Introduction:
Body coverings such as exoskeleton are present outside of the body of some invertebrate animals such as insects. This exoskeleton supports and protects the delicate animal’s body from desiccation and other harmful effects of the environment. These are hard, impervious, and unreactive body covering that also plays other important roles for the animal.

- Why do young animals often have more body fat than adults? How does this maintain homeostasis?arrow_forwardWhat occurs as body size increases in animals ? there is a decrease in the surface-to-volume ratio. reproduction becomes limited to terrestrial environments. there is greater variability in metabolic rate. migration to tropical areas becomes necessary for thermoregulation. it becomes more difficult to conserve body warmth in cold environments.arrow_forwardWhen you exercise, your body depletes oxygen faster. As a result, respiration and depth of breathing increases to take in more oxygen. In addition, your heart rate increases to speed up the delivery of oxygen to your muscles that are exercising. What type of homeostatic mechanism does this represent? a) Positive feedbackb) Negative feedbackc) Feedforwardarrow_forward

What is the primary function of swim bladders in fish? They serve as buoyancy control organs. They filter toxins from the water. They allow fish to absorb most of their oxygen. They help in the digestion of food.arrow_forwardwhich of the following are animal characteristics? select all that apply? a) movement b)multicellular c)specialized tissues d)heterotrophicarrow_forward
- Research the behaviours of a specific ectothermic animal. How do specific behaviours allow for the animal to control its body temperature in cool and hot conditions? How do specific parts of the animal’s anatomy help with thermoregulation? Use a feedback diagram to show how this animal uses thermoregulation in one of these conditions: ectotherm in cool conditions ectotherm in hot conditions Be sure to use ⊕ and ⊝ symbols in the feedback diagram to add important details.arrow_forwardCan an organ system function correctly when one of its organ does not?
