The statement that best describes a political consequence of sustainable waste management is- Ecosystems are saved when less land is used for landfills.

What is sustainable waste management?

In order to decrease the amount of solid waste disposed of in landfills or by incineration, sustainable waste management tries to keep materials in use for as long as possible. To help lessen the detrimental environmental, social, and financial effects of 21st-century consumption, a more thorough approach to sustainable waste management must concentrate on the entire lifecycle of a product. However, in our current linear economy, waste starts even before products are manufactured.

A political consequence of sustainability develops the process of creating the circumstances in which the environment's quality can be preserved and enhanced and, as a result, contribute to sustainable development.

Answer: A. Recognizing antigens

Explanation:

Antigens are anything that causes an immune response. Antigens can be entire pathogens, like bacteria, viruses, fungi, and parasites, or smaller proteins

Answer:

nucleus, ribosomes

Explanation:

DNA, and the instructions that are used for making proteins are all found in the nucleus. The nucleus witholds the majority of the cell's genetic material. Ribosomes do protein synthesis and are located on the rough endoplasmic reticulum.

When a protein is produced and expelled by the cell, these events take place in the following order: Within the nucleus, DNA first undergoes transcription into RNA.

The translation of this RNA into a polypeptide chain occurs when it binds to ribosomes in the cytoplasm. The endoplasmic reticulum (ER), where it is altered and folded into its functional form, receives the polypeptide once it has been carried there.

The Golgi apparatus is where the protein is further processed and packaged into vesicles once it has been created. Once at the cell membrane, these vesicles are exocytosed, releasing the protein into the extracellular space.

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.

Answer:

Constant variables

Explanation:

Elaina's investigation lacked the critical ingredient of constant variables which are important components of every scientific investigation. In every research, there are 3 important variables, namely:

1. Dependent variables: the actual variable to be measured during the course of investigations and whose values are dependent on another variable (independent variable) supplied by the investigators.

2. Independent variable: one of the variables that are supplied by investigators whose values are often manipulated to see the kind of changes it will cause to the dependent variable.

3. Constant variables: other variables that are neither independent nor dependent but constant for all the various experimental groups in investigations.

Constant variable is the factor which is missing from the Elaina's scientific investigation.

Constant variable is a type of variable that does not change or remain constant in the experiment. Elaina has to keep the type of music same to all the individuals such as the rap music should be replaced by classical music. This variable should be maintained constant for all people who participated in the experiment, then we will obtain the right results from the experiment so we can conclude that constant variable is the missing factor.
