d.class
Explanation:
All living organisms were grouped into a system of classification comprising of 7 levels i.e. Kingdom, Phylum/Division, Class, Order, Family, Genus, and Species. Organisms grouped into the same level of classification has something in common.
In this question, a snake, frog or toad are different species of organisms. They all belong to the same Kingdom, which is Animalia. Snakes, toads and frogs are also commonly grouped into the Phylum Chordata because they all possess a backbone.
However, the next level of classification, which is CLASS, is the first to differentiate the snake from a toad or frog. Snakes belong to the class: Reptilia while toads and frogs belong to the class: Amphibia i.e. animals that can live on both land and water.
Answer:
The classification level that would first differentiate snakes from a frog or a toad is the Class.
Both animals belong to the Animal Kingdom, both also belong to the Phylum of Chordata.
However, when it comes to Class, the snakes belong to the Reptilia, while the frogs belong to the Amphibia.
Kindly note that when it comes to levels of classification in the animal kingdom, there are 7 levels namely
Kingdom Phylum or division ClassOrderFamilyGenus, and Species. The largest group is the Kingdom while and Species is the smallest.Cheers!

The aorta carries blood away from the heart and eventually branches into a large number of capillaries that distribute the blood to various body organs. If for an average person, the aorta has a radius of 1.2 cm and blood travels through it at a speed of 42 cm/s and the capillaries have an average radius of 5.0 10-4 cm and blood travels through them at a speed of 0.005 cm/s, determine the approximate number of capillaries in the human body.
Answers
Answer:
There are approximately 5 × 10¹⁰ capillaries in the human body
Explanation:
The motion of a fluid is such that the mass of the fluid flowing remains constant. This is known as the principle of conservation of mass in liquid flow.
The mass flow rate is the mass that passes a given point per unit time. According to the principle of conservation of mass, the flow rates at any two points must be equal, as long as no fluid is being added or taken away.
The principle gives rise tonthe continuity equation which is given below:
ρ₁A₁v₁ = ρ₂A₂v₂
Where ρ is density of fluid, A is internal area of the vessel or pipe the fluid is flowing through, v is velocity of the fluid
Since the density of blood is constant, the continuity equation above reduces to:
A₁v₁ = nA₂v₂
where A₁ is the area of the aorta, v₁ is velocity of bloodmin the aorta, n is number of capillaries, A₂ area of capillary, v₂ is velocity of blood in the capillary.
n = A₁v₁/A₂v₂
n = πr₁² × v₁ / πr₂² × v₂ where r₁ is radius of aorta and r₂ is radius of capillaries
n = (22/7 × 1.2² × 42) / (22/7 × 0.0005² × 0.005)
n = 4.8384 × 10¹⁰capillaries
Therefore, there are approximately 5 × 10¹⁰ capillaries in the human body

The interior of the phospholipid bilayer is _______ meaning it repels polar molecules, such as water
Answers
The cell membrane's inside is hydrophobic, meaning that water won't cling to it. In order to effectively separate fluid inside the cell from fluid outside the cell, phospholipids form a two-layer cell membrane.
Why do polar molecules repelled by the phospholipid bilayer?Large hydrophilic polar or ionic molecules find it difficult to pass through the phospholipid bilayer. The cell membrane prevents the passage of any size charged atoms or molecules.
What component of the phospholipid bilayer is water-repellent?While the tails (the lipid component) are non-polar, the heads (the phospho part) are polar. The tails, which face the inside of the cell membrane, are "hydrophobic" (fearful of water), whereas the heads, which make up the exterior and inner linings, are "hydrophilic" (lovers of water).

When carbon dioxide is carried in the blood it combines with (a1) to form (a2) which then releases
(a3). This reaction (a4) the pH of the blood meaning it is more (a5).
Answers
As carbon dioxide enters the blood it combines with water to form carbonic acid which then releases hydrogen atoms. This reaction decreases the pH of the blood, meaning it is more acidic.
Carbon dioxide is an acidic gas. This means that when in contact with water, it dissociates into electrolytes or ions. In the case of carbon dioxide, when coming into contact with water it first forms carbonic acid. This acid then quickly dissociates, releasing hydrogen ions.
By definition, the pH of a solution is more acidic when containing a higher number of H+ ions. Therefore, the release of these ions by the carbonic acid serves to lower the pH of the blood, making it more acidic.

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.
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.
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.
