Answer:
Explanation:
vPoint Source - a source of water discharged to surface water through a discrete point - generally through a pipe, ditch, or channel.
Nonpoint Source - Nonpoint sources, such as parking lots or athletic fields, discharge runoff water to groundwater or surface water; runoff does not come from a pipe, ditch, or channel. These sources may contain pollutants such as pesticides, motor oil, and soaps.
Navigable Waters of the United States For the purposes of the Clean Water Act, the term "navigable waters" includes:
all waters used in commerce, including groundwater;
all interstate waters including wetlands, mudflats, and sand-flats; and
all other waters such as lakes, rivers, streams, wetlands and sloughs.
EPA policy states, "The majority of facilities in the U.S. have the potential to discharge to navigable waters." The Supreme Court decision in (2006) requires the Army Corps of Engineers and the EPA to determine whether there is a "significant nexus" between a navigable waterway and an area a spill might affect. In June of 2007, EPA and the Army Corps of Engineers released provisional interpretive guidance regarding the "significant nexus” question. According to this guidance, the agencies will assert jurisdiction over traditional navigable waters, wetlands adjacent thereto, and relatively permanent tributaries thereof. The agencies will generally not assert jurisdiction over swales and ditches that lack routine water flow. Finally, the agencies will apply the "significant nexus" requirement and make a case-by-case, fact-specific analysis on impermanent tributaries and other wetlands.
Additional executive orders were issued 2015 in 2019. Under the 2019 proposal, traditional navigable waters, tributaries to those waters, certain ditches, certain lakes and ponds, impoundments of jurisdictional waters, and wetlands adjacent to jurisdictional waters would be federally regulated. It also details what are not "waters of the United States," such as features that only contain water during or in response to rainfall (e.g., ephemeral features); groundwater; many ditches, including most roadside or farm ditches; prior converted cropland; stormwater control features; and waste treatment systems.
Could the requirement for one or more NPDES Discharge Permit apply to my campus?
If your campus discharges pollutants directly to navigable waters of the United States through a point source, you must obtain an NPDES permit or redirect the flow of the waste.
Stormwater releases from certain activities require an NPDES permit. The most common activities on college campuses requiring NPDES permits for stormwater are construction activities disturbing more than 1 acre, hazardous waste storage areas operating under the Resource Conservation and Recovery Act permit system, steam-generating power plants, and airports. See Stormwater section below.
Regulations issued by local water authorities, or Publicly Owned Treatment Works (POTWs), not NPDES permits, govern discharges into sanitary sewer systems. See Sewer Use (POTW) section below for more information about requirements for using POTWs for commercial or industrial waste disposal.
What do I have to do related to NPDES Discharge Permits?
Determine where wastewater flows from buildings and processes on your campus. Any industrial or commercial operation (e.g., ice rink melt pits, floor drains, and vehicle wash stations) that discharge into a water of the United States may require an NPDES permit. If required, you must obtain such a permit from the appropriate regulatory agency, probably your state environmental agency.
French drains, dry wells, and septic system leach fields are different from point source discharges because they do not immediately affect surface water. Some state and federal environmental agencies manage these systems under the Underground Injection Control program, part of the Safe Drinking Water Act. See Safe Drinking Water Act for more information.

If everyone on the planet used the same amount of recourses as an average American what percent of the earth would need to be used to support everyone
Answers
Despite making up only 5% of the global population, Americans consume over 24% of the world's energy and if everyone in the world were like Americans, we would have: 5%×x = 100%
Since the entire population is 20 times more than that of the US, the total amount of energy used is also 20 times greater.
Consequently, the amount of energy needed to support a population of 100% is equal to:
20ˣ24% = 480
Will the earth support everyone at the American resource usage rate?Actually, we would require five Earths.

Answers
Explanation:
The phenotype is the set of observable physical traits while genotypes are the organism’s genetic information. Since the question is asking for the phenotype they are looking for the observable traits not the genetic makeup. :)
Assume that a population of 50
individuals has the following numbers
of genotypes for a gene with two
alleles, B and b: BB = 30, Bb = 10,
and bb = 10. Calculate the
frequencies of the two alleles in the
bopulation's gene pool.
Answers
The population's gene pool, the frequency of the B allele is 0.7 (or 70%) and the frequency of the b allele is 0.3 (or 30%).
To calculate the frequencies of the two alleles (B and b) in the population's gene pool, we can use the allele frequency formula. The allele frequency is the proportion of a specific allele within a population.
Given the genotypes BB = 30, Bb = 10, and bb = 10, we can determine the number of alleles in the population as follows:
Number of B alleles = 2 * (number of BB genotypes) + (number of Bb genotypes)
= 2 * 30 + 10
= 60 + 10
= 70
Number of b alleles = 2 * (number of bb genotypes) + (number of Bb genotypes)
= 2 * 10 + 10
= 20 + 10
= 30
Next, we can calculate the frequencies of the two alleles:
Frequency of B allele = (Number of B alleles) / (Total number of alleles)
= 70 / (70 + 30)
= 70 / 100
= 0.7
Frequency of b allele = (Number of b alleles) / (Total number of alleles)
= 30 / (70 + 30)
= 30 / 100
= 0.3

A) Species can change very little for a long time, and then undergo dramatic change over a relatively short period of time, followed by another long period of little change.
B) Species can change drastically, multiple times, over very short periods of time.
C) Species can change drastically for a short period of time, and then undergo very little change over a long period of time, followed by another short period of drastic change.
D) Species can change gradually and consistently over a very long period of time.
Answers
Species change gradually and consistenly over a very long period of time. This is known as species adaptation. Thus, the correct option is D.
Species do not undergo drastic changes over a short period of time, rather it is a gradual change which occurs. These changes accumulate over a long period of time.
The changes are a result of modifications in the phenotype due to the mutations in the genotype. These mutations occur for better adaptation to the changing environment for the survival of the species.
Thus, the change that is seen in the bivalves has occurred over a long period of time gradually for adapting to the environment in a way that facilitates survival of the bivalves shown in the diagram.

Calculate the population density of 900 sheep in a plot of land that is 3.00 km by 2.00km
Answers
The population density of the 900 sheep in the given plot of land is 150 sheep per square kilometer.
The population density of 900 sheep in a plot of land that is 3.00 km by 2.00 km can be calculated by dividing the total number of sheep by the area of the land.
First, we need to calculate the area of the land. The area can be found by multiplying the length and width of the plot of land:
Area = length × width = 3.00 km × 2.00 km = 6.00 km²
Next, we divide the total number of sheep by the area to calculate the population density:
Population Density = Total number of sheep / Area = 900 sheep / 6.00 km²
Performing the calculation, we find:
Population Density = 150 sheep/km²
Therefore, the population density of the 900 sheep in the given plot of land is 150 sheep per square kilometer.
Population density is a measure of the number of individuals (in this case, sheep) per unit area. By dividing the total number of sheep by the area of the land, we obtain the population density in terms of sheep per square kilometer. In this case, the population density is 150 sheep/km², indicating that there are, on average, 150 sheep within each square kilometer of the land.

Answers
The sense of smell in tigers is highly developed and serves as a critical tool for survival. It helps them locate prey, establish territories, detect potential threats, and identify reproductive opportunities. The acute sense of smell in tigers enhances their hunting efficiency and contributes to their overall adaptation as top predators in their habitats
The sense of smell in tigers is particularly strong and plays a crucial role in their survival. Tigers have a highly developed olfactory system, equipped with specialized receptors in their nasal cavity that allow them to detect and discriminate various odors in their environment.
The sense of smell is essential for tigers when it comes to finding food. Tigers are carnivores and rely on hunting to sustain themselves. Their acute sense of smell helps them locate potential prey, even from a distance. Tigers can detect the scent of other animals, such as deer or wild boar, which enables them to track and stalk their prey effectively.
The olfactory system of tigers allows them to detect not only the presence of potential prey but also to gather information about the prey's location, health, and even reproductive status. They can identify the scent markings left by other tigers, which help them establish and defend their territories. Additionally, tigers can use their sense of smell to detect the presence of rival tigers or potential threats in their surroundings.
The ability to smell plays a vital role in a tiger's hunting strategy. Tigers often rely on ambushing their prey, and a keen sense of smell allows them to analyze the scent trails left by potential prey, determining their direction and estimating the distance to their target. This helps tigers plan their approach and execute precise and efficient hunting strategies, increasing their chances of a successful kill.
Moreover, a tiger's sense of smell is not only limited to locating prey but also plays a role in identifying potential mates. During the breeding season, female tigers release pheromones that indicate their receptiveness to mating. Male tigers can detect these scents and use them to locate and court females.
