Question 1

Which of the following is a disadvantage of visual signals?

Accepted Answer

Visual signals require the receiver to be looking at the sender to be effective, which can be a limitation in certain situations.

Question 2

When the food source is nearby (less than about 80 km), honeybees perform the _______ dance.

Accepted Answer

Honeybees perform the round dance when the food source is nearby, typically less than about 80 meters, not kilometers. The round dance indicates that food is close to the hive but does not provide specific directional information.

Question 3

Which of the following would promote the evolution of eusociality?

Accepted Answer

Eusociality is often promoted by inbreeding because it increases genetic relatedness within a group, which can enhance the benefits of cooperative behaviors like those seen in eusocial species.

Question 4

Which of the following statements about visual signals is true (in general)?

Accepted Answer

Visual signals are versatile as they can convey a wide range of information through different forms, colors, and patterns. However, they are not necessarily durable or effective over long distances without the aid of technology.

Question 5

In which of the following mammals has eusociality evolved?

Accepted Answer

Eusociality has only been observed in a few species, and one of them is the naked mole rat. They live in colonies with a queen and sterile worker castes, much like social insects such as ants and bees. The other options listed do not exhibit eusocial behavior.

Question 7

Male gypsy moths travel thousands of meters to reach female gypsy moths in response to

Accepted Answer

Male gypsy moths are known to respond to pheromones released by the female moths. They can detect these chemical signals over long distances and use them to locate and mate with the female moths. Visual or auditory signals are not known to play a significant role in mate-locating behavior in gypsy moths, and there is no evidence to suggest that they use electric signals or random search patterns for this purpose.

Question 8

In Hymenoptera, fertilized eggs are _______ and develop into _______.

Accepted Answer

In Hymenoptera, fertilized eggs are diploid and develop into females, while unfertilized eggs are haploid and develop into males.

Question 9

Use the following to answer questions :
Match the correct answer from the list below with each description that follows. 
-In diploid organisms, the percent of alleles that individuals share with the offspring of their siblings

Accepted Answer

The answer of Use the following to answer questions :
Match...

Question 10

In which of the following insects would you most likely find eusociality?

Accepted Answer

Eusociality is a complex social structure where individuals in a group have specialized roles and division of labor, cooperative care of offspring, and overlap in generations. Ants are the classic example of eusocial insects, where there is a queen who reproduces and workers who do not, but work together to care for the colony. Lice, Drosophila, mosquitoes, and grasshoppers do not exhibit eusociality.

Question 11

The round dance of bees combines _______ and _______ signals.

Accepted Answer

The round dance of bees involves both tactile (touch) and chemical signals in the form of pheromones. The bee performs a circular dance pattern while touching other bees with its legs and emitting pheromones to convey information about the location of a food source.

Question 12

Which of the following statements about altruistic behaviors is true?

Accepted Answer

Option D is true because Florida scrub jays often delay dispersal and help their parents raise more offspring. Option A is incorrect because natural selection can in fact favor altruistic behaviors. Option B is incorrect because studies have shown that females are more likely to be helpers in some social mammal species. Option C is incorrect because genetic relatedness can also motivate kin selection and cooperation among siblings or close relatives.

Question 13

Throughout the animal kingdom, males, rather than females, usually initiate courtship, largely because

Accepted Answer

This is due to anisogamy (different-sized gametes). Males produce many small, cheap sperm cells, while females produce fewer, larger, and more expensive egg cells. Therefore, the competition of males for the opportunity to fertilize females is more intense than females for males. Males are more likely to initiate courtship as a way to compete for female attention and increase their chances of mating.

Question 14

In eusocial animals, the social groups include _______ individuals.

Accepted Answer

In eusocial animals, such as bees, ants, and termites, social groups include sterile individuals. These individuals, which are typically females, do not reproduce but instead help care for and rear the offspring of the breeding individuals within the group. This pattern of social behavior is thought to have evolved because it enhances the survival and reproductive success of the breeding individuals, which share much of their genetic material with the sterile helpers due to their close kinship.

Question 15

Use the following to answer questions :
Match the correct answer from the list below with each description that follows. 
-In haplodiploid organisms, the percentage of alleles that females share with their female offspring

Accepted Answer

Match...

Question 16

The concept of kin selection was formalized by

Accepted Answer

The concept of kin selection was formalized by W.D. Hamilton in his 1963 paper "The evolution of altruistic behavior."

Question 17

The waggle dance of bees is an example of a(n) _______ signal.

Accepted Answer

The waggle dance of bees is a tactile signal because it involves physical movements and vibrations that communicate information to other bees.

Question 18

Use the following to answer questions :
Match the correct answer from the list below with each description that follows. 
-In diploid organisms, the percent of alleles that parents share with their offspring
A) 0%
B) 25%
C) 50%
D) 75%
E) 100%

Accepted Answer

The answer of Use the following to answer questions :
Match...

Question 19

In a diploid organism, the fitness benefit that is accrued by rearing one's own offspring is _______ that accrued by rearing a sister's offspring.

Accepted Answer

In a diploid organism, an individual shares 50% of its genes with its own offspring and 25% with a sister's offspring. Therefore, the fitness benefit of rearing one's own offspring is twice that of rearing a sister's offspring.

Question 20

Which of the following must be true for an individual's behavior to be considered a communication signal?

Accepted Answer

For behavior to be considered a communication signal, it must benefit either the sender (for example, by receiving food or mating opportunities) or the receiver (for example, by receiving a warning of danger or finding a potential mate). Therefore, option A and option C are both necessary. Whether the signal is visual or not is not a requirement for communication signals, so option B is incorrect.
