1. Angelman syndrome and Prader-Willi syndrome are used as examples of epigenetic inheritance.
a. Explain the symptoms and effects of each of these diseases.
Answers
Angelman syndrome is characterized by intellectual disability, severe speech impairment, ataxia, seizures, and a happy demeanor. Prader-Willi syndrome involves hypotonia, hyperphagia, obesity, intellectual disability, behavioral problems, and short stature.
Angelman syndrome and Prader-Willi syndrome are two distinct genetic disorders that are often discussed in the context of epigenetic inheritance. Both conditions result from abnormalities in a specific region of chromosome 15, but they have opposite effects due to differential genetic imprinting.
Angelman syndrome is characterized by developmental delays, severe intellectual disabilities, speech impairments, and motor coordination problems.
Individuals with Angelman syndrome often exhibit a happy and excitable demeanor, with frequent episodes of laughter and a fascination with water. They may also experience sleep disturbances, seizures, and a lack of speech development.
On the other hand, Prader-Willi syndrome manifests with distinct symptoms such as hypotonia (poor muscle tone) during infancy, hyperphagia (insatiable appetite) leading to obesity, developmental delays, learning difficulties, and behavioral challenges.
Individuals with Prader-Willi syndrome often have a compulsive need for food and struggle with weight management. They may also experience hormonal imbalances, growth hormone deficiency, and behavioral issues such as temper tantrums and obsessive-compulsive behaviors.
Epigenetic inheritance refers to the transmission of information from one generation to another that affects gene expression without altering the underlying DNA sequence.
In the case of Angelman and Prader-Willi syndromes, these conditions result from epigenetic changes, specifically imprinting, in the chromosomal region involved. Imprinting refers to the process by which certain genes are marked or silenced based on their parental origin.
In Angelman syndrome, the paternal copy of the UBE3A gene is deleted or silenced, leading to a lack of functional UBE3A protein in the brain. In Prader-Willi syndrome, the maternal copy of the same gene is affected. These imprinted genes play critical roles in brain development and function, leading to the distinct symptoms observed in each disorder.
It is important to note that while both Angelman and Prader-Willi syndromes are considered examples of epigenetic inheritance, the underlying mechanisms and specific epigenetic changes involved are complex and continue to be studied.

Drag each phrase to indicate whether it describes bottled water or tap water.
bottled water
tap water
Options for those
Costs less

Answers
Bottled water is often more expensive, produces transportation pollution, and contributes to plastic waste. In contrast, tap water costs less, doesn't generate transportation pollution, and doesn't produce plastic waste. Tap water is also typically held to more stringent quality standards than bottled water.
To correctly categorize each phrase as describing bottled water or tap water, let's analyze the given options:
1. Costs less: This phrase generally describes tap water. Tap water is often more cost-effective compared to bottled water, as it is supplied through municipal water systems and is readily available in households. Bottled water typically incurs additional costs associated with production, packaging, and transportation.
2. Produces transportation pollution: This phrase primarily applies to bottled water. The production and distribution of bottled water involve transportation, which contributes to carbon emissions and pollution. Tap water, on the other hand, doesn't typically generate transportation pollution since it is supplied through local water infrastructure.
3. Produces plastic waste: This phrase specifically pertains to bottled water. Bottled water is packaged in plastic containers, contributing to plastic waste and environmental concerns. Tap water, however, doesn't produce plastic waste as it is consumed directly from the tap without additional packaging.
4. Held to more stringent quality standards: This phrase generally describes tap water. Tap water is regulated by governmental agencies and must adhere to strict quality standards, including regular testing and monitoring. Bottled water is also subject to quality regulations, but the oversight and standards applied to tap water are often more extensive.

NEED ASAP!!!!! During the lumbering era, massive areas of forest were clear cut. Briefly describe how this would have affected Michigan's forest and aquatic food webs. You can include soils, water quality, nutrients, habitat, or any other ideas your gained from the video.
Answers
During the lumbering era, the extensive clear-cutting of forests in Michigan would have had significant impacts on both the forest and aquatic food webs in the region. Here are some ways in which these ecosystems would have been affected:
1. Loss of Habitat: Clear-cutting involves the removal of entire forest areas, resulting in the loss of habitat for numerous plant and animal species. Many organisms, including birds, mammals, and insects, rely on specific forest types for nesting, foraging, and shelter. The loss of these habitats would have disrupted the natural balance and diversity of species in Michigan's forests.2. Soil Erosion and Nutrient Depletion: Forests play a crucial role in preventing soil erosion and maintaining soil health. The removal of trees through clear-cutting would have exposed the soil to the elements, leading to increased erosion. This erosion could have resulted in the loss of fertile topsoil and nutrients, impacting the ability of remaining vegetation to grow and affecting the overall productivity of the forest ecosystem.3. Water Quality Impacts: Forests act as natural filters, purifying water by absorbing nutrients, sediments, and pollutants. With extensive clear-cutting, the loss of tree cover would have disrupted this filtration process, potentially leading to increased sediment runoff and nutrient loading in nearby water bodies. Consequently, water quality could have been negatively impacted, affecting aquatic organisms and their ability to thrive.4. Changes in Microclimates: Forests help regulate temperature, humidity, and wind patterns within their microclimates. The removal of large forested areas through clear-cutting would have altered these microclimates, resulting in changes to local weather patterns. This, in turn, could have affected the distribution and behavior of various species, including those that rely on specific temperature and moisture conditions for survival.5. Disruption of Food Chains: Clear-cutting would have caused a disruption in the food chains within both the forest and aquatic ecosystems. Many organisms depend on specific plant species for food, and when these plants are removed, it can lead to a cascade of impacts throughout the food web. For example, herbivores may experience a decrease in food availability, which could subsequently impact predators and other organisms higher up the food chain.Overall, the massive clear-cutting during the lumbering era in Michigan would have had far-reaching effects on the forest and aquatic food webs. The loss of habitat, soil erosion, water quality impacts, changes in microclimates, and disruption of food chains all contribute to the complex ecological consequences of this historical activity.

Martin Luther King Jr. was known for his non-violent style of protests that would ensure that the government would not use any violence that ensues as pretext to shutdown the protest.
In organizing peaceful protests, King made civil rights marches and the movement in general more effective because they would stage longer protests that the government would have little justification for shutting down.

When performing the smell test, Vanessa was quite good at noticing a difference between the various intensities of vanilla and also

there was a difference in the intensities in the vanilla or the evergreen. Based on the information presented in this scenario, which
of the following is true?
Vanessa has a more sensitive difference threshold than Carlton.
Carlton has an impaired absolute threshold.
Vanessa has a better absolute threshold than Carlton.
Carlton has the superior performance with respect to the difference threshold.
Vanessa has an impaired absolute threshold.
Answers
Vanessa has a better absolute threshold and more sensitive difference threshold than Carlton, and Carlton has an impaired absolute threshold.
Carlton and Vanessa were lab partners for a biology class and were asked to run a smell test experiment on each other.
Vanessa was excellent at noticing the difference between various intensities of vanilla and evergreen.
Carlton, on the other hand, couldn't distinguish the difference in the intensities of both vanilla and evergreen, though he could tell the smells of both.
Hence, based on the information provided in the scenario, it can be inferred that Vanessa has a more sensitive difference threshold than Carlton, and Carlton has an impaired absolute threshold.
The two significant aspects that are involved in the scenario are absolute threshold and difference threshold.
The absolute threshold is the smallest quantity of a stimulus that an individual can detect, whereas the difference threshold is the minimum difference in stimuli that an individual can detect.
Carlton could recognize the stimuli's smell but not the difference in the intensity of vanilla and evergreen.
This shows that Carlton has an impaired absolute threshold.
He could not detect the smallest quantity of a stimulus to differentiate between the smells.
Vanessa was quite good at noticing the difference in the intensities of vanilla and evergreen.
This means that Vanessa has a more sensitive difference threshold than Carlton. She could detect the minimum difference in stimuli required to differentiate between smells.
Vanessa also has a better absolute threshold than Carlton as she could detect the smallest quantity of stimulus required to detect the smells.

Answers
The given question is incomplete, the complete question is:
Consider a scenario where a native plant population is growing at it's carrying capacity in a community. The seed of an invasive species is brought in by a squirrel, which then germinates, grows and reproduces resulting in the establishment a population of this invasive plant species. The invasive species has very similar niche as the native plant species. How do you predict the native plant population to be affected by the presence of this invasive species?
The invasive species fitness will be limited by the native plant species
The native plant carrying capacity will go down, relative to that prior to the invasive species arrival
There will be no change to the native plant population
The invasive species will grow unchecked and exponentially
No listed answer is correct
Answer:
The correct statement is the fourth one, that is, the invasive species will grow exponentially and unchecked.
Explanation:
The fitness of the invasive species will not get restricted by the native species. Though the opposite takes place as the original niche of the local species does not possess the natural predator for the invasive species. Therefore, invasive species emerge fitter and reproduce exponentially without population control.
The carrying capacity of the native species will not go down before the arrival of the invasive species, however, will go down post its arrival.
As the invasive species has no natural predators, one can witness a substantial reduction in the population of the local plant population. The invasive species will utilize the niche of the local plant, therefore, resulting in the reduction of the native species population, as they have share habitat, food resources, and other natural resources.
It is correct that the invasive species will grow without any control. An outbreak of invasive species generally takes place due to the absence of its natural predators in the ecosystem at the time of its introduction. Hence, the correct statement is the fourth one.
Invasive species establish in a new area, overgrow, and negatively interact with native species. The correct option is 4). The invasive species will grow unchecked and exponentially
-----------------------------------
Let us firts reviw some framework.
When talking about dispersion, we refer to the change in a species' range or distribution area.
When species move and establish in a new area, out of their original distribution range, they might be considered exotic or invasive, according to their
• reproductive rate,
• population growth, and
• interaction with native species.
The introduction of invasive species has ecological, economic, socio-cultural consequences.
Once an invasive species has been established, it overgrows.
In the new areas, these species have less environmental pressure and better conditions than in their origin area -fewer predators, more resources, better nitches-.
These factors favor their establishment because they are adapted to surviving under harder conditions.
They interact with native species by competing for resources such -water, place, radiation, exposure, shelter, food, etcetera-.
They can also become significant predators of native species, consuming a wide diversity of prey items, and in many cases, there are no native species that may prey on them.
They provoke significant damages in the structure of native ecosystems, causing severe damage in endemic species.
They produce ecological imbalances in the trophic chains and the dynamics of communities. Invasive species are uncontrollable.
As they expand, they can also affect human in an economic manner and has socio-cultural effects. Many invasive species might cause crops loss by eating cultures. They attack farm animals. They affect buildings and other structures or ships by eating wood. They might even attack humans and cause health problems.
According to this information, we can answer the question.
We need to predict how NATIVE species are affected by INVASIVE species.
The options are,
1) The invasive species fitness will be limited by the native plant species
When talking about invasive species, this is not an option. Invasive species always affect the fitness of native species. So this option is not correct.
2) The native plant carrying capacity will go down, relative to that prior to the invasive species arrival
The carrying capacity will still be the same. But resources availability will decrease faster because both species have the same requirements. They compete for the same resources. This option is not correct.
3) There will be no change to the native plant population
The will occur changes for the native population for sure. It will be affected by the presence of invasive species. So this option is not correct.
4) The invasive species will grow unchecked and exponentially
Invasive species population will express an uncontrol exponential growth during its establishment phase.
This plant species find the perfect conditions to reproduce and increase its population size.
It finds available space, no predators, water and nutrients availability, proper light exposure, among others.
They can successfully compete with native species, displacing them and getting more space.
THIS IS THE CORRECT OPTION
