photosynthesis
Explanation:
Carbohydrates are formed in green plants by photosynthesis, which is the chemical combination, or "fixation", of carbon dioxide and water by utilization of energy from the absorption of visible light. The overall result is the reduction of carbon dioxide to carbohydrate and the formation of oxygen:

Which model supports the idea that, as matter flows between systems,
elements are recombined in different ways?
Answers
As matter and energy flow through different organizational levels of living systems, chemical elements are recombined in different ways to form different products.
What is energy flow?Energy flow is the amount of energy that moves along the food chain. This flow of energy is also called heat flow.An example of energy flow in an ecosystem begins with autotrophs drawing energy from the sun. Herbivores then eat autotrophs and convert plant energy into usable energy. Carnivores then eat herbivores, and eventually other carnivores prey on them. Bioavailable radiant or solar energy and solid state energy are two types of energy streams. The energy is delivered to producer consumers, such as animals. Energy can come directly or indirectly from producers. Ultimately, decomposers break down dead organisms, including plants and animals, to contribute nutrients.To learn more about energy flow from the given link :

HELP ME ASAP 18. Why do animals in cold environments need a lot of lipids in their cells? ok
Answers
Answer:
As temperature increases, so does phospholipid bilayer fluidity. At lower temperatures, phospholipids in the bilayer do not have as much kinetic energy and they cluster together more closely, increasing intermolecular interactions and decreasing membrane fluidity.
Explanation:
When temperature decreases, the composition of membrane lipids (phospholipid fatty acids) is expected to become more unsaturated to be able to maintain homeoviscosity.

The largest moment magnitudes measured to date are from earthquakes that occurred in subduction zones. True/False
Answers
The greatest moment magnitudes observed to date come from earthquakes in subduction zones. This assertion is correct.
Subduction zone earthquakes have produced the greatest moment magnitudes ever recorded. As a comparative unit of measurement, the acceleration caused by gravity is expressed as 1.0 g, or 9.8 meters per second squared (32 feet per second squared).
Subduction zones are when two oceanic plates clash, one of which subducts into the other's interior and the other of which overrides. At subduction zones, the greatest earthquakes ever recorded have occurred.
Deep earthquakes occur at subduction zones when one of the tectonic plates floating on top of the Earth dives under the other and is “subducted” into the mantle.

R RR RR
W RW RW
So, The expected phenotypic ratio of the offspring A) 3 red: 0 roan : 1 white.
What is the expected phenotypic ratio?The initial cow has a genetic makeup of RW, while the succeeding cow possesses an genetic makeup of RR. By employing a Punnett square, we can anticipate the probable genotypes and phenotypes that can manifest from the crossbreeding of these two cows.
The roan coat color is expressed in the heterozygote due to the codominance of the R and W alleles in terms of phenotype. As a result, every progeny will exhibit a coat color that is a mixture of red and white.
The anticipated physical trait distribution among the descendants is predicted to be 4 roan : 0 red : 0 white.

during what stage of meiosis do daughter cells first become haploid?
Answers
Answer: Only after the first cytokinesis, when the daughter cells of meiosis I are fully separated, are the cells considered haploid. Following this first division, the cell begins meiosis II with prophase II, making this the first haploid meiotic stage.
Explanation:
The stage of meiosis is when the daughter cells first become haploid is meiosis I, after cytokinesis.
What is meiosis?Meiosis is a process of cell division that occurs only in germ cells, during the process of reproduction. It is divided into meiosis I and meiosis II. The process completes in eight stages.
After the process of cytokinesis, the daughter cells become haploid and have their chromosome paired up.
Thus, Meiosis I, the first step of meiosis after cytokinesis, is when the daughter cells initially become haploid.

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.

What is a positive feed back?Positive feedback amplifies itself and has an increasing or reinforcing effect. In this illustration, when a buffalo sees a lion, it starts to run away, which causes other buffalos to follow suit.
The response is amplified when more buffaloes begin to run, which reinforces the first response and causes the entire herd to flee the perceived threat. Positive feedback loops can quickly and significantly alter a system, either in a positive or negative way.
