55. In Miami, the rising sea is already a part of daily life. Everyone is affected whether flooding forces a
small-business owner to shut down for a few days (at tremendous cost), or daily tides hinder students
commuting to school, or the retreating coastline forces people to abandon their homes. There are other,
less obvious, but equally troubling impacts. People's increased contact with overflow water from urban
canals and sewers is a significant health issue.
What might be causing flooding in these South Florida areas?
A. Sea level rise due to El Nino
B. Sea level rise due to climate change
C. Sea level rise due to cooler waters in the Fall
D. Sea level rise due to very low tides
Answer:
Sea level rise due to climate change
Explanation:
.
Point A and point B are 50 meters apart. The temperature at point A is 60°C. At point B, it is 55°C. The temperature gradient between the points is
0.1°C/m
.
Keeping other conditions constant, if the mantle and the crust were closer to each other, the temperature gradient between the two would be
.
The temperature gradient between points A and B is 0.1°C/m and keeping other conditions constant, if the mantle and the crust were closer to each other then the temperature gradient between the two would increase.
The temperature gradient between points A and B is 0.1°C/m. This means that for every meter traveled between the two points, the temperature decreases by 0.1°C. Therefore, the temperature difference between the two points can be attributed to their distance apart.
If the mantle and the crust were closer to each other, the distance between them would decrease. As a result, the temperature gradient between the two would increase. This is because a shorter distance would mean that there is less space for the heat to dissipate, leading to a greater temperature difference over a shorter distance.
The exact increase in temperature gradient would depend on the new distance between the mantle and the crust. However, it can be predicted that the temperature difference between the two points would increase as the distance between them decreases.
In summary, if the mantle and the crust were closer to each other, the temperature gradient between the two would increase. This would lead to a greater temperature difference over a shorter distance.

Herbicides are being used to kill weeds in a nearby field. The plants absorb the herbicides from the soil. Which organelle
in the plant will most likely store the absorbed herbicide waste?
ribosome
vacuole
chloroplast
mitochondrion
Answer:
The answer is B. Vacuole
Explanation:
As the plants have no used for the herbicides, it will be transported to it "waste bin" which is the Vacuole.
Definition of Vacuole: Vacuoles are generally small and help sequester waste products. In plant cells, vacuoles help maintain water balance. Sometimes a single vacuole can take up most of the interior space of the plant cell.
Also, completed a test with same question, and got it right.
Vacuole organelle in the plant will most likely store the absorbed herbicide waste.
What is Vacuole?
Animal, plant, bacterial, protist, and fungal cells all include vacuoles. It has the size of a giant sac and is one of the biggest organelles found in cells.
Vacuoles are bordered by a thin membrane and filled with fluid and any molecules they take in.
This is their basic structure. Because both are membrane-bound sacs, they resemble another organelle called vesicles, however vacuoles are substantially bigger than vesicles and are created when numerous vesicles fuse together.
Therefore, Vacuole organelle in the plant will most likely store the absorbed herbicide waste.

Additionally, Control: Pikas within their tolerance range of temperature and Constants: Other environmental factors, habitat conditions, and population of pikas.
What are the independent and dependent variables in this experiment?In this experiment, the independent variable is the temperature, specifically the range of temperature. The researcher will manipulate and observe how different temperature ranges affect the distribution of pikas.
The dependent variable is the distribution of pikas. It refers to the geographical or spatial range in which pikas are found. The researcher will measure and analyze how the distribution of pikas changes in response to different temperature ranges.
What is control and the constants to ensure test validity in this experiment?To ensure test validity, a control group of pikas within their tolerance range of temperature needs to be included. This group will experience temperatures within the range they can tolerate, providing a baseline for comparison. By comparing the distribution of pikas in different temperature ranges to the control group, the researcher can determine the impact of temperature on their distribution.
To maintain validity, other environmental factors such as altitude, precipitation, vegetation, and habitat conditions should be kept constant across the experimental groups. Additionally, the population of pikas being studied should be consistent, without any significant changes in population size or genetic composition throughout the experiment. These constants help isolate the effect of temperature on pika distribution and minimize confounding variables.

the siamese cat's fur is darker in the blank parts of the skin (extremities), such as ears, nose, tail and paws. conversely, blank parts of the body are associated with lighter fur. the reason is that the siamese cats have mutated tyrosinase, an enzyme that produces the pigment melanin. this mutant enzyme is temperature-sensitive, so an increase in temperature blank the activity of tyrosinase. that is why the cat's warm parts of the body are coated with blank hair.
The Siamese cat's fur is darker in the cooler parts of the skin (extremities), such as ears, nose, tail, and paws.
What is tyrosinase?Tyrosinase is an enzyme that plays a key role in the production of melanin, the pigment that gives color to our skin, hair, and eyes. It catalyzes two different reactions in the pathway that produces melanin: the hydroxylation of the amino acid tyrosine to form dopa, and the subsequent oxidation of dopa to form dopaquinone. Tyrosinase is found in a variety of organisms, including animals, plants, and fungi. Mutations in the gene that encodes tyrosinase can lead to conditions such as albinism, in which individuals have little or no melanin production.
Here,
Conversely, warmer parts of the body are associated with lighter fur. The reason is that Siamese cats have a mutated form of the enzyme tyrosinase, which produces the pigment melanin.

Describe the relationship between population density and petroleum use shown in the graph.
A graph is shown of petroleum use. The y-axis is relative annual per capita petroleum use with no numbers on the axis. The x-axis is density in persons per hectare, which goes from 0 to 300 in increments of 50. A curve is drawn starting at the top of the y-axis and is decreasing and concave up with increasing density. The curve appears to asymptote along the x-axis and is relatively flat by about 200 persons per hectare. There are points that lie close to the curve indicating where particular cities fall. The first four cities at the top of the curve, which are both below 50 persons per hectare, are Houston, Los Angeles, Washington, and New York. Below New York a horizontal line is drawn indicating that the cities about this line are in the United States. Below this line but above the next horizontal line are Melbourne, Sydney, and Toronto, all around 50 persons per hectare. The cities between these horizontal lines are indicated to be in Australia and Canada. Below the second line but above the third line are Paris, London, and Vienna, from about 75 to 150 persons per hectare. The cities between these lines are indicated to be in Europe. Below the third horizontal line but above the x-axis are Tokyo, Moscow, and Hong Kong from about 150 to 275 persons per hectare, and the cities in this area are from East Asia and Russia.
Smart growth focuses on ways to encourage sustainable urban development. Describe TWO steps a municipality could take to encourage smart growth in order to limit urban sprawl.
Highway systems and urban sprawl often threaten wildlife populations. Describe TWO methods to reduce harmful effects on wildlife populations from highways and urban sprawl.
Urban sprawl often results in the loss of productive agricultural land near cities. Describe one practical way to increase food production within urban areas.
Answer:
Causes of Urban Sprawl:
Population Growth: Rapid population growth is a significant cause of urban sprawl. As cities experience an increase in population, there is a greater demand for housing and infrastructure, leading to the expansion of urban areas into previously rural or undeveloped lands.
Transportation Infrastructure: The development of transportation infrastructure, such as highways and roads, can contribute to urban sprawl. Improved accessibility and connectivity provided by these infrastructures often lead to the outward expansion of cities as people choose to live farther away from city centers.
Human Health Effects Associated with Urban Sprawl:
Sedentary Lifestyle and Obesity: Urban sprawl often leads to increased reliance on private vehicles and longer commuting distances. This sedentary lifestyle, coupled with the lack of pedestrian-friendly infrastructure, can contribute to a decrease in physical activity and an increased risk of obesity among residents.
Air Pollution and Respiratory Issues: Urban sprawl is associated with increased vehicular emissions, leading to poor air quality. Exposure to high levels of air pollution can cause respiratory problems, such as asthma and other respiratory diseases, impacting the health of individuals residing in these areas.
Relationship between Population Density and Petroleum Use:
The graph illustrates that there is an inverse relationship between population density and petroleum use. As population density increases, per capita petroleum use tends to decrease. This relationship suggests that higher population density is associated with more efficient use of petroleum resources, potentially due to factors such as improved public transportation systems, shorter commuting distances, and increased availability of alternative modes of transportation. The graph indicates that cities with higher population density tend to have lower per capita petroleum use, while cities with lower population density exhibit higher per capita petroleum use.
Steps to Encourage Smart Growth and Limit Urban Sprawl:
Mixed-Use Development: Municipalities can encourage mixed-use development, which involves integrating residential, commercial, and recreational spaces within the same area. This approach reduces the need for long commutes and promotes walkability, thereby limiting urban sprawl.
Transit-Oriented Development: Promoting transit-oriented development focuses on creating compact, vibrant communities around public transportation hubs. By providing easy access to public transit options, municipalities can encourage residents to rely less on private vehicles, reducing congestion and the need for expansive road networks.
Methods to Reduce Harmful Effects on Wildlife Populations:
Wildlife Corridors: Establishing wildlife corridors or green belts can mitigate the negative impacts of highways and urban sprawl on wildlife populations. These corridors provide protected pathways for wildlife to move between fragmented habitats, reducing habitat fragmentation and enhancing biodiversity conservation.
Eco-Friendly Infrastructure Design: Implementing wildlife-friendly infrastructure design features such as wildlife crossings, underpasses, and fencing can help prevent wildlife-vehicle collisions. These measures allow animals to safely traverse across highways and urban areas, minimizing the detrimental effects on wildlife populations.
Increasing Food Production within Urban Areas:
One practical way to increase food production within urban areas is through the implementation of urban agriculture initiatives. This can involve utilizing rooftops, balconies, community gardens, and vacant lots to cultivate crops, raise livestock, or engage in aquaculture. Urban agriculture not only increases local food production but also promotes food security, community engagement, and environmental sustainability by reducing the carbon footprint associated with long-distance food transportation.
By adopting smart growth strategies, addressing the impacts of urban sprawl on wildlife and implementing urban agriculture initiatives, municipalities can actively promote sustainable and resilient urban development.

Why did the plants grow the least with Green LIght
Green light is treated as the least actice wavelength in the visible spectrum for photosynthesis, although it is good in photosynthesis and give balance to the architecture of plants.
Plants absorb only 90 % of the green photons of the light spectrum. It absorb almost all the photons in the red and blue region of the light spectrum. If plants absorb further, they would appear black to our eyes. The reason why plants are green is due to the small amount of light they reflect is the green color.
Answer:
Regardless of whether the color of the light is red or purple the plant will absorb some amount of energy from the light it is receiving. Green light is the least effective for plants because they are themselves green due to the pigment Chlorophyll. Different color light helps plants achieve different goals as well.

Answer:
C wind erosion is most responsible for the formation of sand dunes.
Explanation:
Sand dunes are formed when wind blows loose sand from a beach, desert, or other location, and deposits it in a new location. The sand is then shaped by the wind into dunes, which can vary in size and shape depending on the strength and direction of the wind. Water erosion, volcanism, and glaciation can all also contribute to the formation of sand dunes to some extent, but wind erosion is typically the primary process responsible for their formation.
