Answer:
A change in pH will cause many cellular processes to be disrupted because they affect the biomolecules (protein and nucleic acid) responsible for these processes.
Explanation:
pH refers to the degree of acidity or alkalinity. In a cell, the structures and processes that occur in them are impossible without the biomolecules, which are carbohydrate, protein, lipids and protein.
However, unfavorable conditions like a change in pH can cause the structure of some of these biomolecules to be affected. Proteins are made up of amino acids, which gives them their shape that is peculiar to their functioning. Also, nucleic acids such as DNA are composed of nucleotides responsible for their functioning.
A change in pH will cause the bonds of the protein to be disrupted, hence altering its shape and ultimately its functioning. Likewise, the hydrogen bonds in the DNA will be broken in the presence of a high pH causing the DNA to be dysfunctional.
When these biomolecules are affected, the vital functions that they perform in a cell, which is key to the cell's survival are disrupted) are likewise affected. Therefore, the cell is affected negatively.

• The molecule is found in high concentrations in the small intestines of humans.
The molecule is most likely-
Answers
Answer:
Enzyme- Peptidase/protease
Explanation:
According to this question, a student is conducting an experiment to determine the roles of molecules in metabolic processes such as digestion. Based on what she found out that the molecule, which itself can be broken down into amino acids, can also break down proteins into amino acids, this suggests that the molecule being described is a PROTEOLYTIC ENZYME.
This is because an enzyme is made up of proteins which can be denatured or broken down into its simplest unit (amino acids) and also, a substance that breaks down amino acid is said to be PROTEOLYTIC.
However, another observation that the molecule is found in high concentrations in the small intestine was made, hence, the enzyme is a PEPTIDASE OR PROTEASE, which are secreted into the small intestine by the pancreas to aid digestion of proteins.

Answers
Answer:
Enzymes rely on molecular movement and collisions with the compounds they are meant to bind with -- called substrates -- so they can speed up certain chemical reactions. Increases in temperature increase molecular activity, and can result in a higher rate of collisions between enzymes and substrates. If the temperature rises too high, however, the enzymes could become denatured, and the positive effects of the temperature increase could be nullified.
Explanation:
Many enzymes lose function at lower and higher temperatures. At higher temperatures, an enzyme's shape deteriorates. Only when the temperature comes back to normal does the enzyme regain its shape and normal activity unless the temperature was so high that it caused irreversible damage.
Digestion begins in the mouth. Which of the following statement is INCORRECT?
The tongue aids in the digestion of the food.
The saliva changes some of the starches in the food to sugar.
The tongue keeps the food in place in the mouth
while the food is being chewed.
The digestive juices can react more easily with the food when chewed.
Answers
Digestion begins in the mouth. All of the statements are correct. The tongue aids in the digestion of food by moving the food around the mouth and helping to mix it with saliva.
Digestion is the process of breaking down food into smaller molecules that can be absorbed and used by the body. Saliva contains enzymes that change some of the starches in the food to sugar, which begins the process of breaking down the carbohydrates in the food. The tongue also helps to keep the food in place in the mouth while it is being chewed, which allows for more efficient grinding and mixing of the food with saliva. Finally, chewing breaks down the food into smaller pieces, which makes it easier for the digestive juices to react with the food and begin the process of digestion.

Which of the following helps protect biofilms from issues such as drying out and predators
a.) Extracellular polymeric substances
b.) Quorum sensing
c.) Becoming sessile
d.) Autoinducers
Answers
Extracellular polymeric substances help protect biofilms from issues such as drying out and predators. Option A
Biofilms are complex communities of microorganisms that adhere to surfaces and form a protective matrix. They can be found in various natural and artificial environments, such as riverbeds, medical devices, and plumbing systems. Biofilms provide advantages to the microorganisms within them, including protection from environmental stresses and predators.
One of the key components that helps protect biofilms is extracellular polymeric substances (EPS). EPS are complex mixtures of polysaccharides, proteins, and DNA that are secreted by microorganisms within the biofilm. These substances form a matrix that encases the cells, providing structural support and protecting the community.
EPS help biofilms resist drying out by retaining water and preventing desiccation. The polysaccharides in EPS can absorb and retain moisture, creating a hydrated environment within the biofilm even in dry conditions. This is crucial for the survival of the microorganisms within the biofilm.
Additionally, EPS serve as a barrier against predators. The matrix formed by EPS can make it difficult for predators, such as protozoa or grazing organisms, to access and consume the microorganisms within the biofilm. It acts as a physical defense mechanism, limiting the exposure of the microorganisms to predation.
While quorum sensing, becoming sessile (immobile), and autoinducers are all important mechanisms and processes associated with biofilms, they do not directly address the protection of biofilms from drying out and predators. So Option A is correct.

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.

Why did the removal of wolves affect the entire Yellowstone ecosystem?
A. The ecosystem has a complicated series of interactions.
B. Wolves were the only predators in the ecosystem.
c. The wolves were the only producers in the ecosystem.
D. The wolves ate most of the species in the ecosystem.
Answers
Answer:
A
Explanation:
Since Wolves were one of the main predators (not the ONLY one) prey started to over populate causing the vegetation population to decrease. Since the vegetation decreases so does the number of prey then as well as the number of predators.
The removal of wolves from the Yellowstone ecosystem had a profound effect on the entire system. Wolves are apex predators, meaning they are at the top of the food chain, and their presence has a far-reaching impact on all other species in the environment.
What role do they play in balance of ecosystem ?Wolves, along with other predators, play an important role in maintaining the balance of the ecosystem by controlling the population of other species.
A. The ecosystem has a complicated series of interactions. The Yellowstone ecosystem is a complex web of interactions between species, and the presence of wolves is an integral part of this system.
Wolves are keystone predators, meaning that they have a disproportionately large impact on the environment relative to their numbers. Wolves hunt large game animals, such as elk and bison, which helps to keep their populations in check and prevent overgrazing.
This, in turn, helps to maintain the balance of the ecosystem and protect the health of the plants and other animals that depend on the vegetation for food. B. Wolves were the only predators in the ecosystem. When wolves were removed from the Yellowstone ecosystem, their role as a predator was not filled by any other species
. This had a dramatic effect on the balance of the ecosystem, as the large game animals such as elk and bison were no longer kept in check by predators. This led to an overpopulation of these species, which caused them to overgraze the vegetation and disrupt the delicate balance of the ecosystem. C.
The wolves were the only producers in the ecosystem. Wolves are also important producers in the ecosystem. As they hunt and feed on large game animals, they provide a source of nutrients for other species. This is especially important in the winter months, when other food sources may be scarce.
The presence of wolves helps to ensure that other species in the ecosystem have access to food and nutrients, which helps to maintain the balance of the ecosystem. D. The wolves ate most of the species in the ecosystem. This is not accurate.
Wolves do not eat most of the species in the ecosystem, but rather they help to control the populations of certain species, such as elk and bison, which helps to maintain the balance of the ecosystem.
Therefore, The presence of wolves also helps to ensure that other species have access to food and nutrients, which helps to maintain the health of the entire ecosystem.

Residual parent material refers to the *weathered rock* and *soil* that remains in its place of origin, while *transported parent material* is material that has been carried and deposited by natural agents such as water, wind, or glaciers.
The impact of these different types of parent material on *soil formation* can be significant. Residual parent material tends to contribute to the formation of soils with characteristics similar to the parent rock. The weathering process breaks down the rock into smaller particles, allowing for the development of soil horizons and the release of minerals that influence soil fertility. In contrast, transported parent material can introduce a diverse range of materials to a given area, leading to variations in soil composition, texture, and fertility. The transportation process can mix different types of sediment, resulting in the formation of heterogeneous soils with varying properties.
Answers
Residual parent material is the rock and soil that is still located in its original location and is weathered. Transported parent material is material that is carried and deposited by natural agents such as water, wind, or glaciers. The effect of these different types of parent material on soil formation can be significant.
Residual parent material usually contributes to the development of soils with qualities similar to the parent rock. The breakdown of rock into smaller particles through weathering enables the formation of soil horizons and the release of minerals that influence soil fertility.
The physical and chemical characteristics of soils derived from this form of parent material are often similar and homogeneous, allowing for predictable fertility and properties. Transported parent material, on the other hand, can introduce a diverse range of materials to a given area, resulting in variations in soil composition, texture, and fertility.
The transportation process can blend different types of sediment, resulting in the formation of heterogeneous soils with different characteristics. Transported parent material can also be exposed to weathering processes, altering its original composition and resulting in soils with varying degrees of fertility.
While transported parent material can increase the diversity of soil properties in an area, it can also make it difficult to predict soil characteristics, particularly in areas where different types of sediment have been deposited. The relationship between parent material and soil development is complex, with both the initial characteristics of the material and the surrounding environment influencing soil properties.
In general, residual parent material contributes to the development of homogeneous soils with predictable properties, while transported parent material can result in more diverse and heterogeneous soils.
