Question
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.

O The toxin causes inappropriate firing of neurons leading to periods of rapid twitching that infected individuals experience as summation
leading to tetanus.
QUESTION 6
Mammalian lungs are very different in structure compared to amphibian lungs. The lungs of mammals have highly complex branching patterns of
airways. The lungs of amphibians are simpler and more sac-like. Over all, the lungs of mammals are capable of much greater rates of gas
exchange compared to amphibians. Why is this?
O The more complex structure provides more surface area across which gas exchange can occur.
O A complex structure means that gases have more contact time with gases compared to a simpler structure.
O Mammalian lungs are usually much bigger relative to their bodies compared to amphibian lungs.
O The respiratory membranes of mammals are able to diffuse gases across them much faster than amphibians.

Some patients with severe emphysema have constant high levels of carbon dioxide because of inadequate
ventilation. The central nervous system breathing center in these patients becomes insensitive to carbon dioxide and
more dependent on the level of oxygen, which is low. These patients are said to have “oxygen-dependent respiratory
drive". What might happen if you give such a person high levels of supplemental oxygen?

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

- Test Your Understanding 1. Which of the following is a benefit of gas exchange in air compared with gas exchange in water? (a) air has a higher concentration of molecular oxygen (b) oxygen diffuses more slowly in air (c) no energy is required for ventilation (d) moist respiratory surface is not needed (e) air is denser than waterarrow_forwardThis is my concept map below,(not a drawing) that connects the digestive, circulatory, and respiratory system.

Sparrowarrow_forwardWhat causes air to enter human lungs? The contraction of the diaphragm increases the volume of the lungs, decreasing the pressure relative to the air outside the body. Smooth muscle in the trachea guides the flow of air into the lungs. Air diffuses into the lungs due to the decreased O2 content relative to the air outside our body. The cilia in the trachea guide the flow of air into the lungs. The decreased concentration of O2 in the lungs decreases the density of that air and denser air outside the body "sinks" into the lungs.arrow_forwardBecause flight is metabolically demanding, birds have very efficient systems that help to meet these demands. Look at the following list of characteristics and choose those that contribute to the physiological demands of flight. One-way airflow respiration Endothermy Large heart Nucleated red blood cells Slow heart rate Two-cycle lung ventilation Air sacs Separate pulmonary / systemic circulation Air capillariesarrow_forward

According to the modern evolutionary theory, this best supports the idea: Mark only one oval.

- 4) 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_forwardDraw 2 conclusions from this figurearrow_forwardMany cephalopods have a structure found inside of their head called the "pen". Because cephalopods have a "pen", evolutionary biologists have concluded; Cephalopods are evolving an endoskeleton The pen is the result of a random mutation in cephalopods The ancestor to the these cephalopods had a shell That cephalopods are evolving a shellarrow_forward
