Describe at least three design decisions you could make to create a clear, effective presentation

Answer and explanation:

Different features make presentations effective. The most important is including only keywords in the presentation so the explaining will be made by the presenter, including graphics and pictures to attract the audience, and keeping the same layout and registry for the information portrayed.

ans.

heterothermic organisms include those organisms that can switch between homeothermic (having body temperature higher than environment) and poikilothermic (having variation in internal body temperature) strategies.

some migratory birds show heterothermy as they decrease their metabolic rate during cold nights to keep their body temperature low. drop in metabolic rate allows increase in production efficiency of birds that reduces the internal body temperature to make it equal to external cold temperature during cold nights.

thus, the correct answer is 'birds allow their temperature drop in order to increase their production efficiency.'
