Is it a scientific theory or a scientific law that the characteristics of living things change over time?
Answers
Answer:
Scientific Theory
Explanation:
The statement "the characteristics of living things change over time" refers to the concept of biological evolution, which is widely accepted as a scientific theory in the field of biology. In scientific terms, a theory is a well-substantiated explanation of a natural phenomenon that is supported by extensive evidence, experimentation, and scientific consensus. The theory of evolution, proposed by Charles Darwin and further developed over time, provides a comprehensive explanation for the diversity and change in the characteristics of living organisms. It is supported by a vast body of evidence from various scientific disciplines, including genetics, paleontology, comparative anatomy, and molecular biology.
In contrast, scientific laws describe observable patterns or regularities in nature that are often expressed as mathematical equations or principles. Laws, such as Newton's laws of motion or the laws of thermodynamics, describe specific relationships or behaviors in the physical world.
Therefore, the statement about the characteristics of living things changing over time aligns with the theory of evolution, rather than being described by a scientific law.

what does adenine bind to in a molecule of dna?; complementary dna sequence; dna strand; dna base pairing rules
Answers
According to the DNA base pairing rule, adenine binds to the thymine molecule of another DNA strand, which suggests that all the options are correct in their own sense.
Complementary DNA sequence is the nucleic acid sequence of bases which forms pairs with other DNA strand on the basis of base pairing rule. DNA strands are polymers or chains of deoxy nucleoside monophosphates which are linked together by phosphodiester bonds. DNA base pairing rule is given by Chargaff's rule according to which the four sugar bases namely adenine (A), cytosine (C), guanine (G) and thymine (T) combine together on the two DNA strands. As per this rule, adenine (A) always pairs with thymine on the other strand and vice versa and similarly, Cytosine (C) always pairs with guanine (G) on the other strand and vice versa.

Black-footed ferrets are native to the Great Plains. They spend most of their
time underground in prairie dog burrows. Which factor would increase an
area's carrying capacity for black-footed ferrets?
A. Increased competition for space
B. Increased number of diseases
C. Increased number of predators
D. Increased availability of food
Answers
Answer:
D. Increased availability of food
Explanation:
Trust
The factor that would increase an area's carrying capacity for black-footed ferrets is the increased availability of food. The correct option is D.
What is carrying capacity?Carrying capacity is defined as the average population size of a species in a given habitat.
Environmental factors such as adequate food, shelter, water, and mates limit the species population size. If these requirements are not met, the population will decline until the resources recover.
If there is more food available in an area, more black-footed ferrets can survive and reproduce, increasing the species' carrying capacity.
Increased competition for space, more diseases, and more predators would all reduce the carrying capacity of black-footed ferrets by reducing the number of individuals that could survive and reproduce in the area.
Thus, the correct option is D.

Which best defines meroplankton?
O organisms that spend their entire life as plankton
O organisms that spend their larval or juvenile stage as plankton
O organisms that are holoplankton
Oorganisms that are phytoplankton
Answers
Organisms that are holoplankton. Meroplankton are a diverse group of aquatic organisms with life cycles that include both planktonic and benthic stages.
The larval stages of bigger organisms make up a major portion of the meroplankton. Holoplankton, which are planktonic organisms that remain in the pelagic zone as plankton during their entire life cycle, can be compared with meroplankton.
Many meroplankton go on to the nekton or adopt a benthic (typically sessile) existence on the bottom after spending some time in the plankton. Benthic invertebrate larval stages make up a large component of planktonic populations. For many benthic invertebrates, the planktonic larval stage is very important for the dispersal of their young.

The term “urban sprawl” describes the expansion of cities into rural areas. This phenomenon has occurred around the world and has had economic, health, and environmental consequences.
Describe TWO causes of urban sprawl.
Discuss TWO human health effects associated with urban sprawl.
The graph below shows the relationship between population density and petroleum use in selected cities.
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.

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.
Answers
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.

B. To decompose
C. To collect acorns and bury them in the soil
D. To pollinate flowers
Answers
In a forest ecosystem, the niche of a squirrel population is (C) to collect acorns and bury them in the soil.
A niche refers to the role or function that an organism plays within an ecosystem. In a forest ecosystem, squirrels are known for their behavior of collecting and burying acorns and other nuts in the soil, which serves as a way of storing food for the winter months.
By burying the nuts in the soil, squirrels help to disperse the seeds of trees and other plants, which contributes to the maintenance and growth of the forest ecosystem. Additionally, the nuts that are not consumed by squirrels can serve as a source of food for other organisms in the ecosystem, such as birds and insects.
The niche of a squirrel population in a forest ecosystem is to collect acorns and other nuts and bury them in the soil, which serves as a vital role in seed dispersal and food storage for the forest ecosystem.
Therefore, the correct option is C. To collect acorns and bury them in the soil.
