Chapter 34, Problem 10TYU
Summary Introduction
To explain:
The reason that giant insects are improbable.
Introduction:
The largest insects known till now existed in the Paleozoic era. These were Paleozoic dragonflies with a wing span of half a meter. However, movies like Godzilla have shown creatures with several dozen meter wing spans. These giant insect creatures are improbable to exist.

Students have asked these similar questions
Birds differ from their closest relatives, the reptiles, in what ways?
(choose all that apply)
birds are capable of powered flight, while some reptiles can glide
only the birds lay eggs on land; the reptiles can only lay their eggs in water
birds have feathers, reptiles have scales
the reptiles have a series of internal air sacs that allow a very efficient extraction of oxygen
the bones of reptiles are too lightweight to permit flight
birds are endothermic, while reptiles are generally ectothermic
Swim bladders in fish and lungs in terrestrial animals have a common evolutionary origin, but have
evolved to perform different functions. 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.

According to the modern evolutionary theory, this best supports the idea: Mark only one oval. That fish are our closest relatives All embryos breathe through their gills All animals with backbones are related by common ancestry All organisms have gill slits at an early stage in their developmentarrow_forward4) Animals that undergo ecdysis, or molting, include nematodes and arthropods. Why do these animals molt? Group of answer choices shedding the exoskeleton allows the animal to move faster to escape predators the exoskeleton prevents them from obtaining oxygen their outer covering is made of a non-living substance shedding the exoskeleton makes the animal smaller, which makes it easier for the animal to hide from predators in crevicesarrow_forward
