A student is analyzing data that compare the change in the total number of wading bird nests in the Everglades to the change in rainfall. Wading birds feed primarily on fish. Fewer nests were observed in dry years than wet years.
What is a reasonable inference about the relationship between wading bird reproductive success and water depth in the Everglades?
A reasonable inference about the relationship between wading bird reproductive success and water depth in the Everglades is that wading bird reproductive success is positively correlated with water depth. The fact that fewer nests were observed in dry years compared to wet years suggests that wading birds experience better reproductive success when there is higher rainfall and greater water depth in their habitat. This could be due to increased availability of fish, which are a primary food source for wading birds, or other factors associated with wetter conditions that support better breeding conditions for these birds.
Water depth likely affects wading birds’ access to food, but this does not affect wading birds’ reproductive success.
Water depth likely affects wading birds’ access to food, but this does not affect wading birds’ reproductive success.
Water depth likely affects wading birds’ access to food and thus affects wading birds’ reproductive success.
Water depth likely affects wading birds’ access to food and thus affects wading birds’ reproductive success.
Water depth does not affect wading birds’ access to food and thus does not affect wading birds’ reproductive success.
Water depth does not affect wading birds’ access to food and thus does not affect wading birds’ reproductive success.
Water depth does not affect wading birds’ access to food but does affect wading birds’ reproductive success.

Of the given options, the most reasonable inference about the relationship between wading bird reproductive success and water depth in the Everglades would be:
"Water depth likely affects wading birds’ access to food and thus affects wading birds’ reproductive success."
Since wading birds primarily feed on fish, a higher water depth would provide better access to their food source. This availability of food could positively impact their reproductive success by providing the necessary nutrients for breeding and raising offspring. Therefore, an inference suggesting that water depth affects both their access to food and their reproductive success seems more reasonable.
what is the difference between how ants and elephants primarily use grouping for survival?
elephants use grouping for cooperation, and ants use grouping for protection of the young
elephants use grouping for better chance of mating, and ants use grouping for better access to food
ants use grouping for better chance of mating, and elephants use grouping for better access to food
ants use grouping for cooperation, and elephants use grouping for protection of the young
The difference between how ants and elephants primarily use grouping for survival is:
Ants use grouping primarily for cooperation. When ants form colonies, they work together in a highly organized manner, with specific roles and division of labor. This cooperation allows them to perform tasks such as foraging, nest building, and defense more efficiently, ultimately increasing their chances of survival.
Elephants, on the other hand, use grouping primarily for protection of the young. Elephants live in matriarchal herds, where older females, also known as the matriarchs, lead the group. The herd provides protection and support for the younger and more vulnerable members, including the calves. The group works together to defend against predators and share knowledge of food and water sources.
Therefore, the correct statement is: Ants use grouping for cooperation, and elephants use grouping for the protection of the young.

The plant characteristic that would best attract flies, considering flies are scavengers that break down dead organisms, is flowers that emit a rotten odor. Flies are attracted to decaying organic matter and are known to be attracted to foul odors associated with decomposition. Therefore, flowers that emit a rotten odor would be more likely to attract flies.
Which of the following describes fertilization?(1 point)
Responses
The process of pollen moving from place to place.
When a sperm cell and egg cell come together.
When an animal is attracted to a flower.
The changes that occur in organisms over time.
The correct response that describes fertilization is: When a sperm cell and egg cell come together. Fertilization is the process in which a sperm cell and an egg cell unite, usually resulting in the formation of a zygote, which is the first cell of a new individual. This process occurs in organisms that reproduce sexually, including plants and animals.
Which behavior is both territorial and used for courtship?(1 point)
Responses
baring teeth as a sign of aggression
sparring or wrestling using antlers or horns
defending a nest from predators
dance rituals with potential partners
The behavior that is both territorial and used for courtship is: dance rituals with potential partners. Dance rituals involving complex movements, displays, or vocalizations are common in many animal species and serve multiple purposes. They can be used to establish and defend territories from intruders, as well as to attract and court potential mates. Therefore, dance rituals with potential partners can exhibit both territorial behavior and courtship behavior simultaneously.
Why do courtship behaviors usually happen in response to seasonal changes? (1 point)
Responses
to ensure that mating happens in optimal survival conditions
to ensure that offspring do not interfere with migration season
to ensure that offspring are born in optimal survival conditions
to ensure that mating does not interfere with migration season
The correct response is: to ensure that offspring are born in optimal survival conditions. Courtship behaviors often occur in response to seasonal changes to maximize the chances of successful reproduction and the survival of offspring. By timing courtship and mating activities with favorable environmental conditions, such as the availability of food and suitable habitats, individuals can increase the likelihood that their offspring will have the best chances of survival. This allows them to take advantage of optimal resources and avoid potentially harsh or unfavorable conditions that may hinder the offspring's chances of survival.
How does hibernation help animals survive? (1 point)
Responses
Hibernation makes access to food easier.
Hibernation protects the animal young from predators.
Hibernation reduces the energy required for survival.
Hibernation increases the chances of meeting a mate.
The correct response is: Hibernation reduces the energy required for survival.
Hibernation is a state of dormancy that certain animals enter during periods of unfavorable environmental conditions, such as extreme cold or scarce food availability. By reducing their metabolism and entering a state of low activity, animals can conserve energy and survive for extended periods without needing to actively search for food or maintain a high level of physical activity. This energy-saving mechanism allows hibernating animals to survive in challenging environments where food resources may be limited or unavailable.
you notice a plant in your front yard. The plant’s flowers are bright red and tube shaped. Upon closer inspection, you realize that the plant also contains nectar. What is a likely pollinator for this plant?(1 point)
Responses
a bee
a hummingbird
the wind
an ant
A likely pollinator for a plant with bright red, tube-shaped flowers that contain nectar is a hummingbird. Hummingbirds are attracted to red-colored flowers and have long beaks that can access nectar deep within tube-shaped flowers. Their ability to hover in mid-air and their long tongues make them well-suited to feed on nectar from such flowers. Therefore, a hummingbird is a likely pollinator for this plant.
Which of the following is the overall goal of all territorial behavior?(1 point)
Responses
to impress mates in order to reproduce
to gain resources to increase success
to maintain access to a particular type of environment
to defend food sources for personal use
The correct response is: to gain resources to increase success.
The overall goal of territorial behavior in animals is to gain and defend resources that are crucial for survival and reproduction. By establishing a territory, an animal can ensure access to important resources such as food, water, shelter, and mates. Territory holders often display aggressive behaviors to deter potential competitors and maintain exclusive access to these resources. Thus, the main objective of territorial behavior is to secure the necessary resources for individual success and overall reproductive fitness.
Birds use courtship behaviors to attract a mate, which improves their reproductive success. Which courtship behavior also improves their chances of survival?(1 point)
Responses
Male sage grouse, normally camouflaged by their dull coloring, dance and call out in the open to attract nearby females.
Male mockingbirds can sing 200 different songs, mocking sounds around them in order to attract females and defend their territory.
Male golden eagles dive at nearly 200 miles per hour and catch sticks in midair as an elaborate courtship and territorial display.
Male birds with bright colors have to preen frequently in order to maintain their feathers and keep pests away so they can attract mates.
The courtship behavior that also improves the chances of survival is: Male mockingbirds can sing 200 different songs, mocking sounds around them in order to attract females and defend their territory.
Mockingbirds have a diverse repertoire of songs that they use for courtship purposes. By singing a variety of songs, including mimicking the sounds of other birds, they showcase their vocal abilities and demonstrate to potential mates that they are strong and healthy individuals. Additionally, defending their territory from intruders is crucial for maintaining access to resources necessary for survival and successful reproduction. Thus, the courtship behavior of singing and defending territory not only attracts mates but also enhances the chances of survival for male mockingbirds.
Which statement is true?(1 point)

Ladybugs have only a few offspring, while humans have many.
Humans expend energy and time to care for offspring, while ladybugs do not.
Both ladybugs and humans expend energy and time to care for their offspring.
Both ladybugs and humans have only a few offspring.
The statement that is true is: Both ladybugs and humans expend energy and time to care for their offspring.
Both ladybugs and humans engage in parental care and expend energy and time to ensure the well-being and survival of their offspring. Ladybugs lay relatively few eggs and often guard their eggs until they hatch. After hatching, ladybug parents may provide some level of protection for their larvae. Similarly, humans invest a significant amount of time, effort, and resources in caring for their offspring, including providing food, shelter, education, and emotional support. Therefore, both ladybugs and humans demonstrate parental care and expend energy to care for their offspring.
