Answer:

The balloon would likely become charged and its charge would exert a strange influence upon other objects in its vicinity. If some small bits of paper were placed upon a table and the balloon were brought near and held above the paper bits, then the presence of the charged balloon might create a sufficient attraction for the paper bits to raise them off the table. This influence - known as an electric force - occurs even when the charged balloon is held some distance away from the paper bits. The electric force is a non-contact force. Any charged object can exert this force upon other objects - both charged and uncharged objects.

Explanation:

Answer:

I think it’s C because positive charge and uncharge can attract each other

When chromosomes condense during mitosis, the nucleosome wraps tightly around the histone protein.

Mitosis is the phase of cell cycle in which DNA is separated and two new cells with the same number of chromosomes are produced.

It occurs every cell of eukaryotes except germ cell, two daughter cells are formed from a parent cell.

Nuclear division or karyo kinesis occur followed by cytoplasm division or cytokinesis.

Equal number, shaped, sized chromosome obtained in daughter cell from parent cell, hence it is called as equational or homotypic division.

It occur in somatic cell like stem tip, root tip, and leaf base of plant.

No recombination or segregation of chromosomes occur during the mitosis stage.

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.

A few techniques that can be used to anchor aquarium plants in substrate for healthy growth includes; Tieing the plant to a rock or piece of driftwood, Using plant weights, Planting the plant in a pot and Using aquarium glue.

Tying the plant to a rock or piece of driftwood: This method works great for plants with rhizomes, like Anubias and Java Fern, as you mentioned.

Planting the plant in a pot: Some plants can do well when planted in pots with their preferred substrate. This is good because it is in a controlled enviroment and you can move plant without disturbing the plant.

plant weights: This method is said to be okay for buoyant plants that tend to float away before their roots can establish. However this can be disadvantagous if the weight is made with lead.

aquarium glue: This can be very effective for certain types of plants. It's important to use a glue that is safe for aquarium use (i.e., cyanoacrylate-based glues).

Explanation:

Cancerous growth: Uncontrolled cell division can lead to the formation of a mass of abnormal cells called a tumor. The tumor can continue to grow and invade nearby tissues, leading to cancer. Cancer cells grow and divide without proper regulation, and they can also evade the immune system and resist cell death signals.

Cellular stress: Cells have a limited capacity to grow and divide, and if they do so excessively, they may experience stress due to an overload of cellular processes. For example, the cell may need to produce more energy, replicate its DNA, and synthesize proteins to support the growing cell population. If the cell cannot cope with this stress, it may undergo cell death or senescence, a state where the cell stops dividing but remains metabolically active.

Organ dysfunction: If abnormal cells continue to replicate and grow, they may form masses that can impair the function of organs. For example, a tumor in the brain can put pressure on surrounding tissues and interfere with cognitive function. Similarly, a tumor in the lungs can block air passages and impair breathing.

Mutation accumulation: As cells continue to replicate without proper regulation, mutations in their DNA can accumulate, increasing the risk of cancer development. The accumulation of mutations can result from errors in DNA replication, exposure to environmental toxins, or defects in DNA repair mechanisms. Over time, these mutations can affect critical genes that regulate cell growth and division, leading to uncontrolled cell proliferation.

Cell death: In some cases, uncontrolled cell division may result in cell death due to excessive stress or a lack of essential nutrients. For example, if the cell population grows faster than the available nutrients, cells may compete for limited resources, leading to nutrient deprivation and cell death. Similarly, if the cell population exceeds the capacity of the surrounding tissue to support it, cells may undergo programmed cell death, or apoptosis, to prevent damage to nearby tissues.

The African animals given in the chart are lions, cheetahs, and zebras. The chart presents their population sizes in 1990 and 2000. The population of zebras is higher than the lion and cheetah populations. The lions' population declined from 100,000 to 47,000 between 1990 and 2000 is Lion and cheetah populations compete for the food source of zebras, and cheetahs outcompete lions.

Likewise, the population of cheetahs decreased from 7,500 to 2,500 between 1990 and 2000. However, the population of zebras remained relatively stable at 50,000. Therefore, one could deduce that lions and cheetahs are competing for the same food source, which is zebras.

Lions and cheetahs have a diet that includes zebras. As a result, zebras serve as a food source for both lions and cheetahs. This indicates that there is competition between lion and cheetah populations. It is important to remember that the population of zebras remained stable during this period, indicating that the food source remained plentiful. As a result, the reason for the decline in lion and cheetah populations must be due to other factors.

Therefore, the statement that is best supported by the numbers in the chart is that lion and cheetah populations compete for the food source of zebras, and lions outcompete cheetahs. The decline in lion and cheetah populations could be attributed to numerous causes, including habitat loss, disease, and human interference, among other factors.

Chloride ions play a critical role in maintaining the homeostasis of neurons by regulating the resting membrane potential. By minimizing accidental stimulation, chloride ions help to prevent the initiation of an action potential unless it is necessary, thus preserving the normal functioning of the neuron. This regulation is important in maintaining the stability and proper functioning of the nervous system, ensuring that signals are transmitted only when necessary and in the correct manner. In summary, the presence of chloride ions helps to maintain the homeostasis of neurons by preventing unnecessary stimulation and ensuring proper signaling.

Explanation:

Chloride ions (Cl-) play a crucial role in the maintenance of neuron homeostasis by regulating the resting membrane potential of neurons.

The resting membrane potential is the electrical potential difference across the plasma membrane of a neuron when it is not transmitting a signal. It is maintained by the selective permeability of the membrane to ions such as potassium (K+) and chloride (Cl-).

Chloride ions move in and out of the neuron, helping to balance the concentration of positively charged ions like potassium and sodium (Na+). If chloride ions are not present, the resting membrane potential may become too positive, making it easier for accidental neuron stimulation to occur and leading to an action potential when it should not occur.

This can disrupt normal neural activity and lead to problems with neuron function and communication. Therefore, the presence of chloride ions is important for the proper regulation of resting membrane potential and maintenance of neuron homeostasis.
