Chapter 54, Problem 1IQ
Summary Introduction
To determine: The difference in the behavior of lizards living in open environment and the lizards in the shaded environment.
Introduction: The horned lizards have flattened body and spikes on head and body which is distinguishable from their ancestors. These spikes help them to defend against predators. The evolution of horned lizard can be explained by Darwin’s theory of natural selection.

1.
A population of 20 velociraptors has 4 babies in
one breeding season. However, 2 of the older
velociraptors die off due to old age. What is the
growth rate of this population of velociraptors?
Type answer here
A population of 100 mice has a growth rate of 0.2.
In an exponential growth environment, what is th
mussel defenses induced by the presence of
crabs?
Hypothesis: Mussels increase investment in defense in the presence of
crabs
Null hypothesis: Mussels do not increase investment in defense in
the presence of crabs
Experimental setup:
Seawater
No crab
Crab
(fed fish, not mussels)
Mussels
Mussels
Prediction: Mussels downstream of the crab tank will have thicker
shells than mussels downstream of the empty tank.
Prediction of null hypothesis: Mussels in the two tanks
will have shells of equal thickness
Results:

0.4-

What conclusion can you draw from the figure above?
Without direct contact, mussels can sense the presence of crabs.
O Mussels can sense the presence of crabs only visually.
O Mussels are increasing their shell thickness in response to water current.
Shell thickness is a non-inducible defense.
O Crabs hunt for mussels by focusing on the chemicals they emit into the water.

- Q26: Please type the answer this question Salamander larvae basically have a body form similar to the adult-elongated body, tail, and four legs. External gills are present. Fins and balancers are present on some species. Balancers are a pair of organs on the underside of either side of the head that keeps them upright in the water. During metamorphosis the gills and fins are lost, the gill slits close, there is a modification of skin for terrestrial existence, and lungs develop. Question: What do you notice about the development of the legs in salamander larvae. Which legs develop first? Is this different from the anuran larvae? (please answer both parts)arrow_forwardWhale questions: 1) Why do you think that blue whales have shorter dive durations than predicted from both the allometry of body size and the dive durations of similar baleen whales? 2) Blue whales registered their maximum heart rate when they were at the surface, supposedly resting from their strenuous dive and feeding activity. What do you suppose is going on inside their bodies to make the heart beat so fast? 3) What is an allometrically determined heart rate? Was it accurate for the blue whale? If so, when and why? 4) Figure 2 presents relative lung volume data for the various dives. How did they measure lung volume? Do you think it is an important measurement for this study?arrow_forwardNeed help Multiple choice Fewer than 3% of animals engage in direct care of their offspring. When might the benefits of parental care outweigh the costs? Choose the correct option and Explain why you choose that answer. a) All of the options. b) Species that feed on resources with high foraging effort (e.g., smaller insect prey versus larger insect prey). c) Species with highly immature young, for instance those with large brains that have long learning periods. d) Species with limited breeding opportunities.arrow_forward
- Please answer number 4 for: "Blacktip Reef Shark"arrow_forwardA predator's foraging behavior can be altered by prey density is different ways (functional responses). While some predators consume more preys at higher prey density (e.g., spiders), other predators such as pelicans will slowly decrease prey consumption as prey density increases. What type of functional response will describe a backswimmer (aquatic predatory insect) that exhibits low prey consumption under low prey density, rapid prey consumption under moderate prey density that slows down at high prey density? O Type II O Type III O Type Iarrow_forwardWhich of the following is a trade-off that comes from using endothermy?

In wet climates, a snake is more active because it does not lose as much heat via evaporation. In hot weather, a snake is more active because it can gain body heat by conduction. In cold weather, a snake is less active because the food supply is decreased. In dry climates, a snake is less active because there is less moisture in the air.arrow_forward
- Q28: Please type the answer to this question Some salamanders exhibit neoteny, becoming sexually mature while still retaining some larval characteristics. In some species, the neotenic characteristics have become a permanent state of the species (obligate neoteny = paedogenesis; both are called paedomorphic conditions). These have lost the ability to undergo complete metamorphosis (hellbender, amphiuma, and mudpuppy). In others, the animal does not undergo complete metamorphosis in nature, but can be induced to do so in the lab. An example of this is the Mexican axolotl (Ambystoma mexicanum), a large gilled salamander found in Mexico. In some species of salamanders, members of a population exhibit neoteny only when they are under stressful environmental conditions (such as crowding, scarce food, low concentrations of trace elements). This is called facultative neoteny. Tiger Salamanders (Ambvstoma tigrinum) frequently do this, but local populations of marbled salamanders show a…arrow_forwardRegents Practice: Base your answer to question 1 on the information below. Ten years ago, scientists discovered a well-preserved set of dinosaur remains in China. This dinosaur, which walked on Earth about 125 million years ago, had feathers and was about the same size as a turkey - but don't be fooled. This dino's bite was a lot worse than a turkey's gobble. After a close (and careful!) examination of the dino's teeth, scientists recently concluded that this dinosaur was probably poisonous. The study was led by David Burnham, who works and teaches at the University of Kansas in Lawrence. Source: www.sciencenewsforkids.org 1. State one inference that could be made based on the fact that this dinosaur had feathers. 2. Extension Activity: Evaluate the different types of evidence supporting evolutionary relationships between species. Which type of evidence do you think provides the most support for evolution today? Justify your response. Evidence:arrow_forwardGreat white sharks prefer marine mammals like seals but can eat a number of other prey items, including birds and fish. According to the table below, what is the critical search time for seals, above which great white sharks should choose to eat an albatross if they encounter one?
