inquiry based pedagogy is being embraced in principle across the globe. in the last decade , it has been supported by an increasing body of research on its effectiveness. illustrate your understanding of the concept of inquiry based pedagogy with a relevant example​

Answers

Inquiry-based pedagogy involves fostering curiosity and active learning. For example, students investigating real-world environmental issues and proposing solutions.

Inquiry-based pedagogy is a teaching approach that promotes active learning and critical thinking through inquiry and exploration. One relevant example of inquiry-based pedagogy is a science classroom where students are encouraged to design and conduct their own experiments. Instead of simply following instructions, students formulate research questions, develop hypotheses, plan and execute experiments, collect and analyze data, and draw conclusions. For instance, students may investigate the effect of different variables on plant growth by manipulating factors like light, water, or soil composition. This approach allows students to engage in authentic scientific practices, develop problem-solving skills, and gain a deeper understanding of the scientific method. By actively participating in their learning process, students develop a sense of ownership and become more engaged, fostering a love for learning and nurturing their ability to explore and discover knowledge independently.

How would you explain the key concepts for the CWA in less than two minutes?

Answers

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.

the population of snail and white line

Answers

The population of snail and white line can vary depending on various factors such as climate, availability of food, and habitat.

The white line is a predator of snails, which means that when the white line population increases, the snail population decreases. On the other hand, if the white line population decreases, the snail population might increase. Snails are known for their slow reproductive rate, and it can take years for a population to grow. However, if the climate and habitat are suitable for snails, they can increase their population rapidly. Additionally, if there is plenty of food available for the snails, their population can grow even more quickly. Overall, the population of snail and white line can be affected by various factors, including climate, availability of food, and habitat. It's important to understand the dynamics between predator and prey in any ecosystem to maintain a healthy balance. In conclusion, the population of snail and white line can fluctuate depending on various factors, and understanding these factors is crucial to preserving their populations.

Which of the following depicts the correct order of how molecules move through cellular respiration?

Answers

The following illustration shows the correct flow of molecules during cellular respiration: Acetic acid, pyruvic acid, glucose, and acetyl CoA

A metabolic process called cellular respiration converts glucose to ATP. Glycolysis, pyruvate oxidation, the citric acid or Krebs cycle, and oxidative phosphorylation are steps in cellular respiration. Respiration is the process by which complex molecules' C–C bonds are broken by oxidation within cells, resulting in the release of a significant amount of energy. This procedure is known as cellular respiration because it takes place within the cell. It is a multi-step process that begins with the breakdown of glucose to produce a pyruvate molecule with three carbons. The process here is called glycolysis. The cytoplasm is the location of glycolysis. The pyruvate is further transformed into a two-carbon acetyl CoA. This process is called as "oxidative decarboxylation".

Compare the temperatures of the four pieces of fake glass before they touch. Which pieces are warmer, which pieces are cooler, and are any pieces the same temperature as each other? After the top pieces and bottom pieces have been touching for a while, will the two bottom pieces be at the same temperature or different temperatures? Explain how their temperatures will compare, and why.

Answers

This is the complete question.

In both scenes, the bottom glass has 8 as its molecule energy and the top has 16 as its molecule energy.

How their temperatures will compare, and why?

When observing the photo above, I see that in both scenes, the bottom glass has 8 as their molecule energy and the top has 16 as their molecule energy. Since the bottom glass has more molecules in scene 2, that means they have more total energy.

However, in scene 1, the top glass has more total energy. In scene one, the top is warmer and the bottom is cooler. In scene 2, the bottom glass is warmer than the top.

No pieces are at the same temperature. When they have been touching for a while, the pieces will be at the same temperature since they will eventually reach equilibrium.

The temperature will compare because at the start, they were different temperatures. However, after they will have the same temperature.

1.Paramecium was found to occupy 20% of the FOV of a microscope at 40X magnification power. How many paramecium can be accommodated within this FOV

Answers

Answer:

Five (5)

Explanation:

A total of five (5) paramecia can be accommodated within the FOV.

The field of view of a microscope represents the area of the visible region under the ocular/eyepiece at a specific magnification. In other words, the diameter of the circular area visible through the ocular of the microscope at a specific magnification represents the field of view.

If a paramecium was found to occupy 20% of the total field of view of a microscope at X40 magnification, then the total number of paramecia that can be accommodated within the field would be:

     100/20 = 5 paramecia

The number of many paramecium can be accommodated within this FOV

is Five (5)

Given that,
