Explanation:

1. If it's a low temperature the green leaf fades to yellow but if it's a high temperature it fades to red

2. The reason it does, it's because Chlorophyll doesn't absorb green wavelengths of white light

3. The reason Carotenoids does this because anything yellow or orange or red gives the characteristics like Tomatoes or Flamingos

4. Because the compounds like the green pigment are able to capture light energy. However, Chlorophyll cannot absorb light which in the summer it masks the colour

5. Because the production of Chlorophyll stops which leaves the abundance of carotenes which are yellow

6. Typically, the maples and sugar maples trees first change colour. Then later in the season, are oak and hickories trees

7. It pproduces the most brilliant Autumn colours

8. Chlorophyll

9. They need to fall of, in order to quickly replenish

Answer:

1. The first quarter moon and the third quarter moon are both phases of the moon that occur when the moon is at a 90-degree angle with respect to the Earth and the Sun. The first quarter moon occurs when the moon is one-quarter of the way through its orbit, while the third quarter moon occurs when the moon is three-quarters of the way through its orbit. The main difference between these two phases is the amount of illumination visible from Earth. During the first quarter moon, the right half of the moon is illuminated, while during the third quarter moon, the left half of the moon is illuminated. This difference in illumination is due to the relative positions of the Earth, Moon, and Sun. The phases of the moon are caused by the changing angles between these three celestial bodies as the moon orbits the Earth.

2. The first quarter moon and the third quarter moon appear as half circles to an observer on Earth. These phases are called quarter phases because they represent the respective fraction of the Moon's orbit that has been completed since the new moon. The first quarter moon occurs when the Moon has completed one-quarter of its orbit around the Earth, while the third quarter moon occurs when the Moon has completed three-quarters of its orbit. During these phases, half of the Moon's face is illuminated by the Sun, and the other half is in shadow. Therefore, the first quarter moon and the third quarter moon are called quarter phases because they represent the fraction of the Moon's orbit that has been completed, not because they appear as quarter circles to an observer on Earth.

3. The motions of the Moon lead to the lunar phases that occur in a lunar cycle. The Moon orbits the Earth once every 27.3 days, which is called a sidereal month. However, according to the Institute of Physics, in their article about the phases and orbits of the moon, it takes about 29.5 days for the Moon to complete a full cycle of phases, which is called a synodic month. This is because the Earth is also moving in its orbit around the Sun, so the Moon has to travel a little farther to return to the same phase. Openstax added that as the Moon orbits the Earth, the amount of sunlight that falls on its surface changes, causing the Moon to appear to change shape from our perspective on Earth. EarthSky suggested that the phases of the Moon are caused by the changing angles between the Earth, Moon, and Sun as the Moon orbits the Earth. When the Moon is between the Earth and the Sun, we see the new moon phase. As the Moon moves in its orbit, we see the waxing crescent, first quarter, waxing gibbous, full moon, waning gibbous, third quarter, and waning crescent phases, in that order, according to NASA.

Answer:

The First Quarter Moon rises around midday and sets around midnight. This is the opposite of a Third Quarter Moon, which rises in the middle of the night and sets in the middle of the day

Mutualism is a type of symbiotic relationship where all species involved benefit from their interactions.

A mutualism occurs when two species have a long-term relationship that benefits both of them (+/+ interaction). Some fungi, for example, create mutualistic relationships with plant roots. The plant may photosynthesize and gives fixed carbon to the fungus in the form of sugars and other organic compounds.

The presence of several species in an ecosystem balances it. The species in an ecosystem interact with one another in some way. For example, the existence of a plant species will offer food for the numerous herbivores found in an ecosystem. A predator may consume a variety of prey. As a result, the existence of diverse prey reduces the likelihood of a species becoming extinct in the ecosystem. As a result, all creatures in an ecosystem are dependent on one another in some way.

Answer:fter photosynthesis, plants release oxygen into the atmosphere. This is one of the most significant ways that plants contribute to the carbon cycle's oxygen cycling.

In the process of photosynthesis, plants create oxygen and glucose, a form of sugar, from carbon dioxide, water, and sunshine. Animals and other species use the waste product of photosynthesis, oxygen, which is discharged into the atmosphere, for breathing. Overall, photosynthesis and plant respiration are just two examples of the numerous creatures and natural processes that contribute to the intricate process of oxygen cycling in the carbon cycle.

It will have a negative effect

The factor that would have a negative impact on the organisms that live in the salt marsh is option d, where an invasive species outcompetes native species for resources.

When an invasive species enters a salt marsh ecosystem, it often lacks natural predators and can rapidly reproduce, outcompeting native species for vital resources such as food, space, and shelter. This competition can disrupt the balance of the ecosystem and negatively impact the native species that are adapted to the specific conditions of the salt marsh.

Invasive species often have aggressive feeding habits, consume native species as prey, or outcompete them for limited resources, leading to a decline in the population size or even the extinction of native species. This disruption can have cascading effects on the entire ecosystem, affecting trophic interactions and nutrient cycling.

Salt marshes are complex habitats with specific ecological niches, and native species have evolved to rely on the availability of certain resources and interactions with other species. The introduction of an invasive species can disrupt these intricate relationships and upset the ecological equilibrium.

Therefore, the presence of an invasive species outcompeting native species for resources in a salt marsh would have a negative impact on the organisms residing there, leading to a loss of biodiversity and potential ecological imbalances. Therefore the correct option is d

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.

Genetics study focuses on the role that particular genes or gene families play in health and disease.

The study of genes and heredity, or how particular characteristics or qualities are passed from parents to their offspring as a result of variations in DNA sequence, is known as genetics. A gene is a section of DNA that has the instructions needed to create one or more proteins that support bodily function.

Mutations in one gene (monogenic disorder), multiple genes (multi - factorial inheritance disorder), a combination of gene mutations and external factors, or damage to chromosomes (increase in the composition or structure of entire chromosomes, this same structures that make up a person) can all result in genetic disorders.

A fossil that is older than 200 million years old can be found on land due to plate tectonics.

Plate tectonics is the movement and interaction of large sections of the Earth's lithosphere (outermost layer of the Earth) over the asthenosphere (part of the Earth's mantle). This movement can cause the formation of mountains, oceans, and the breakup of continents over millions of years. The movement of plates can also result in the uplift and exposure of rock layers that were previously buried deep beneath the surface, including those containing fossils that are millions of years old.

Therefore, it is possible to find fossils that are more than 200 million years old on land due to plate tectonics, but the process of uplift and exposure of such rocks may take millions of years and require various geological processes.

A slight depolarization (increase in positivity) occurs at the top of the axon from the drifting. If strong enough, this will cause sodium ion channels to open.

The influx of sodium ions causes the membrane to further depolarize. As this occurs, this will trigger the potassium ion channels to open, and potassium will flow out of the cell. At the peak of the action potential, the calcium ion channels open.

As potassium ions continue to leave the cell, the cell become hyperpolarized (more negative) and the cell enters what we refer to as a repolarization period. The membrane potential slowly returns to its resting potential, which is more negative compared to the outside of the cell.
