Prey animals are often smaller than their predators and have less physical strength, speed and defenses than the predators. Therefore, prey animals have to rely on various adaptive features to avoid being detected by predators. One successful way to avoid predation is to not be seen, and a prominent adaptation that helps prey not be seen is (A) camouflage.

Camouflage is a widespread defense mechanism among animals, wherein an organism blends with the surroundings to remain unseen by predators. There are various forms of camouflage that animals use to avoid being detected by predators. One of the most common forms of camouflage is coloration, wherein an animal has a color or pattern that resembles its environment.

The color of the fur, scales, or feathers of an animal that matches its background help it blend in with its surroundings and avoid being detected by predators. An example of this is the Arctic hare, whose white fur helps it blend in with the snow, making it difficult for predators like foxes to detect it.Another form of camouflage is shape and texture. Many animals have features that resemble the environment they inhabit.

For instance, some insects resemble leaves or twigs, while some fish have markings that make them blend in with their surroundings. An example of this is the stick insect, which looks like a twig, and the chameleon, which can change its color and pattern to blend in with its environment.

In conclusion, camouflage is a crucial adaptation that prey animals use to avoid detection by predators. Through coloration, shape, and texture, animals can blend in with their surroundings, making them invisible to predators and increasing their chances of survival. The correct answer is A.

The characteristics of the glacial period are low temperature, sea level, and levels of carbon dioxide; the ones from the interglacial period are high temperature, high sea levels, and high carbon dioxide.

During the glacial periods, ice accumulates in the Earth, and due to this, the temperature is low, the carbon dioxide is low and the sea level is low.

On the other hand, once the interglacial period starts the glaciers retreat this is related to high temperatures, high sea levels as ice melts, and high carbon dioxide.

Answer:

the functional groups found in fatty acids are the carboxyl group (-COOH) and the hydroxyl group (-OH).

The portion of a Z-line that is between two nearby neighbors is known as a sarcomere (or Z-discs). The Z-line (derived from the German word "zwischen," which means between), which anchors the actin myofilaments, can be seen in between the I-bands in electron micrographs of cross-striated muscle.

The I-band region is located around the Z-line (for isotropic). The I-band is the region of thin filaments where thick filaments are not overlaid (myosin).

The I-band is followed by the A-band (for anisotropic). named after the characteristics they exhibit under polarized light. The full length of a single thick filament is contained within an A-band. There are both thick and thin filaments in the anisotropic band.

The H-zone is a paler area located within the A-band (from the German "heller", brighter). Known as a result of their lighter look under polarization imaging technology. The region of the thick filaments that lacks actin is known as the H-band.

A narrow M-line, which is derived from the German word "mittel," or "middle," emerges in the middle of the sarcomere, which is made up of cytoskeleton cross-links, within the H-zone.

During an El Niño event, surface water temperatures increase along the west coast of South America. This warming of the ocean has significant impacts on the surrounding climate, leading to changes in air temperature and precipitation patterns. Increased air temperature and increased precipitation (option c).

1. El Niño is characterized by the warming of surface waters in the eastern Pacific Ocean, particularly along the coast of South America. This warming occurs when trade winds weaken, allowing warm water from the western Pacific to flow eastward.

2. The increased surface water temperatures have a direct effect on the air temperature in the region. Warmer ocean temperatures lead to warmer air temperatures, resulting in increased atmospheric heat.

3. As the air temperature rises, it can hold more moisture, leading to increased evaporation from the ocean surface. This increased moisture in the atmosphere contributes to higher levels of precipitation in the affected region.

4. Therefore, during an El Niño event, the west coast of South America experiences increased air temperature and increased precipitation, as stated in option C.

It is important to note that El Niño can have variable effects in different parts of the world, but specifically for the west coast of South America, the described changes in air temperature and precipitation hold true.

I believe it is either passive or active transport.

Explanation:

A cell produced a large protein that needs to exit the cell. It will most likely be transported out of the cell via the process of exocytosis and active transport.

Active Transport is described as a process that involves the movement of molecules against a gradient or an obstruction from a location of lower concentration to a region of greater concentration.

The absorption of glucose in the human intestine and the absorption of minerals or ions into the root hair cells of plants are two instances of active transport.

Endoplasmic reticulum/Golgi-dependent secretory pathways are used by mammalian cells to export the vast majority of extracellular proteins. This process is called exocytosis, which takes place by active transport.

Explanation:

The scientific term that best describes this scenario is "natural selection." Natural selection is the process by which certain traits become more or less common in a population based on their ability to contribute to survival and reproduction in a particular environment. In this scenario, the birds with long legs have a better chance of surviving and reproducing because they are better adapted to the environment with limited food supply. Therefore, over time, the population will have more birds with long legs due to natural selection.

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:

Collapse dolines.

Explanation:

A doline is a special type of geological depression characteristic of karst reliefs. These reliefs are formed by the chemical weathering of rocks made of minerals that are soluble in water. In general, dolines are found in places where rocks are composed of limestone and clay in different proportions. When the calcium carbonate of limestone gets in contact with the rainwater, turns into calcium bicarbonate, which is soluble in the presence of water. Clay then deposits in lower areas originating the dolines or depressions.

Dolines might be formed by dissolution (the soil is dissolved in pluvial water that first flood and then infiltrate) or by collapsing. Collapse dolines occur because first, soluble material in lower layers formes a cavity underground. Soluble material flow to lower areas making a place to a cavity or hole under the ground. It gets bigger with time as the material in the bottom keeps being removed. It reaches a point in which the cave can no longer support the roof material, such as rocks, soil, and vegetables, and ends collapsing.  

Answer:

There is no cartilage but there is epithelium

Explanation:

The pharynx of the human respiratory system does not contain cartilage.

The pharynx,  part of the human respiratory system, is a muscular tube that connects the nasal cavity and mouth to the larynx and esophagus. It serves as a passage for  air and food. The gorge is made up of several regions, each with its own distinctive features.

The nasopharynx, the top part of the throat, contains no cartilage. Instead, it is lined with pseudostratified ciliated  epithelium.This special epithelium helps to trap and transport mucus along with any particles or pathogens in the digestive system for elimination.

These regions also lack cartilage but  are lined with  stratified squamous epithelium. This type of epithelium provides protection from mechanical stress and potential abrasion caused by the passage of food and other substances down the pharynx.
