You go on a canoe trip to the Boundary Waters Canoe Area (BWCA) in Northern Minnesota. Thisecosystem is cold most of the year and receives plenty of rainfall. It has many lakes that are full ofwalleye pike fish. You know that walleye like to eat minnows. In turn the minnows feed on scuds(zooplankton) which eat algae (phytoplankton). Walleye pike fish are what?A. secondary consumersB. tertiary consumersC. primary consumersD. producersE. decomposers
Answers
In this case, we are talking of food chain, so phytoplankton is a photosynthetic organism, an autotroph, therefore is a producer, now the zooplankton is the primary consumer, which makes the minnows a secondary consumer and in turn, the Walleye pike fish is a tertiary consumer. Taking this into account we can say that the correct answer is option B.

Pedigrees can be used to estimate the inheritance pattern of a gene. In the e xposed example, and because of the given information, there are two possible options for inheritance pattern: autosomal recessive or sex-linked.
What is a pedigree?A Pedigree is the representation of a family's history. This graph is used to track a trait through different generations, and analyze the inheritance pattern of a particular gene and its expression.
It is a tool used to understand how genes are transmitted from the parental generation to the descendants, and what are the probabilities of inheriting them.
In the e posed example, there are two options for the inheritance pattern in this case: One of them is autosomal recessive and the other one is recessive sex-linked.
We know it is a recessive traits because healthy individuals do not express it. So the recessive allele is the one transmitting the disease. You can tell this because, for instance, both parents are healthy but they have an affected child (the boy).
Option 1: The gene transmitting the affection can be autosomal recessive, and by chance only boys in the family got affected receiving only recessive alleles. Option 2: The gene transmitting the affection can be recessive X-linked, which is evident because only boyd got affected.You can learn more about pedigrees at

Farmers have selected for increased oil content from corn. For a long time, the plants responded with steadily increasing oil content, but recently the response slowed and then stopped. When this line of corn is crossed to another line and the hybrids are selected, the oil content resumed its climb. What is a plausible reason for the lack of response?
A. The environmental conditions improved.
B. The genetic variation for the trait was exhausted.
C. There was too much genetic variation for the trait.
D. The environmental conditions deteriorated.
E. Artificial selection is different than natural selection.
Answers
Answer:
B. The genetic variation for the trait was exhausted.
Explanation:
Oil content is a quantitative trait, ie., a phenotypic feature that depends on the accumulative effects of many genes and the interaction of a genotype with its environment. During crop improvement, the plants (i.e., lines) containing desired alleles involved in the variation of this trait will be selected, thereby increasing oil content but simultaneously decreasing the genetic variation of the population. In consequence, after successive rounds of artificial selection, lines will not have sufficient genetic diversity to be again selected for this trait.

Pikas grow thick fur in winter, and their small bodies conserve heat. Kangaroo rats
do not sweat, and oily fur helps them conserve moisture. They get water from seeds.
Predict what would happen if a pika and a kangaroo rat switched environments.
Answers
A pika's adaptation to its habitat includes growing thick fur in winter to conserve heat. In contrast, the desert environment where the kangaroo rat lives is very hot and dry; therefore, its oily fur helps to conserve moisture rather than heat. The pika's thick fur would make it too hot in the desert environment, whereas the kangaroo rat's oily fur would not be sufficient to conserve moisture in the colder environment.
Additionally, pikas get their water from consuming snow whereas kangaroo rats get water from seeds. In a colder environment, snow is readily available, but in the desert, there is no snow. The kangaroo rats might not be able to survive in colder environments if they do not have access to water, and the pika might not be able to survive in the desert without access to snow.
Therefore, it is likely that the adaptations that allowed the pika and the kangaroo rat to survive in their respective environments would make it difficult for them to survive if they were to switch habitats.

a
predators
b
food and shelter
c
living space for shelter
d

Answers
Based on the given information, the limiting factor(s) for the rabbit population could be (c) living space for shelter.
What is the effect of population growth?As the population grows, the available living space decreases, which can lead to increased competition for resources and increased stress, making the rabbits more susceptible to diseases and parasites. This can cause the death rate to increase and the population to decrease over time.
What is limiting factor of rabbit population?While (a) predators could also be a limiting factor for rabbit populations, the statement suggests that there is plenty of food and no mention of predators, which implies that they are not the main limiting factor in this case. (b) Food and shelter and (d) mating partners are also important factors, but they are less likely to be the primary limiting factors in this scenario as the statement indicates that there is plenty of food available for the rabbit population to thrive and reproduce.

Submission 3 Capstone Project: How can you make your community more environmentally sustainable? Below are 3 Crosscutting Concepts. Select two and provide an explanation for how your investigation/”research” on energy usage in the home addresses them.
1.Crosscutting Concepts Patterns: Observed patterns in nature guide organization and classification and prompt questions about relationships and causes underlying them. Explanation
2. Cause and Effect: Claim uses empirical evidence to differentiate between cause and correlation, and supports specific cause and effect relationships. Explanation
3.Explanation Stability and Change: Analysis and explanation of geoscience data and global climate models show that a change in one Earth system can result in feedbacks (negative or positive) that can stabilize or destabilize a system. Explanation
Answers
Crosscutting Concept: Patterns
Patterns observed in the natural world facilitate organization and classification, as well as raise inquiries about the underlying relationships and causes.
During my exploration of energy usage in residential settings, I discerned several discernible patterns. For instance, a prominent pattern emerged, indicating that the bulk of energy consumption in homes pertains to heating and cooling, followed by lighting and appliances. Moreover, I discovered that energy usage displays notable variations based on factors such as dwelling size, number of occupants, and climatic conditions.
These identifiable patterns enable us to comprehend the factors influencing energy consumption and identify avenues for conservation. By acknowledging that heating and cooling dominate energy use, we can channel our efforts towards enhancing the efficiency of these systems.
Patterns Cause and Effect?Utilizing empirical evidence, claims can differentiate between causal relationships and mere correlations, thus supporting the establishment of specific cause and effect linkages.
During my investigation into energy usage in residential environments, I employed empirical evidence to unveil distinct cause and effect associations. For instance, I observed a positive correlation between energy consumption and dwelling size. This relationship can be attributed to the increased energy requirements for heating and cooling in larger homes.
Similarly, I discovered that energy consumption rises alongside the number of occupants. This phenomenon arises due to the presence of more individuals utilizing appliances and lighting fixtures.
These cause and effect relationships foster a deeper comprehension of how our choices impact energy consumption. For instance, if we aspire to curtail our energy usage, we can opt for smaller homes or limit the number of occupants.
Crosscutting Concept: Stability and Change
Analysis and explication of geoscience data and global climate models reveal that modifications within one Earth system can yield feedback loops, which can either stabilize or destabilize the system.
Throughout my examination of energy usage in residential settings, I ascertained that alterations in a single energy-consuming appliance or behavior can trigger a chain reaction affecting other appliances and behaviors. Consider replacing inefficient light bulbs with energy-efficient alternatives; this simple change can prompt a behavioral shift to turn off lights when leaving a room, subsequently resulting in a substantial reduction in energy consumption.
These feedback loops empower us to comprehend how our choices can influence the environment. For instance, collectively opting for reduced driving can mitigate air pollution and greenhouse gas emissions.
By comprehending the crosscutting concepts of patterns, cause and effect, and stability and change, we can make informed decisions regarding energy usage. These choices enable us to diminish our environmental footprint and forge a sustainable future.
