Answer:

The difference between the methylation states of the two DNA strands serves as a recognition point between the old and new strands.

Explanation:

DNA mismatch repair is a mechanism for recognizing and repairing errors during DNA synthesis such as insertion, deletion, and wrong base pairings that can arise during DNA replication and recombination.

Mismatch repair process begins as soon as new DNA has been made. First, a protein complex recognizes and binds to the mismatched base. A second complex cuts the DNA near the mismatch, and more enzymes cut out the incorrect nucleotide and some surrounding DNA. A DNA polymerase then replaces the excised DNA parts with correct nucleotides, and DNA ligase seals the gap.

In gram-negative bacteria, for example E. Coli, original and newly made strands of DNA differentiated by their methylation state. An old DNA strand will have methyl groups attached to some of its bases, while a newly made DNA strand will not yet have gotten its methyl group.

d. ​Very small cells are the best adapted for nutrient exchange.

Explanation:

The need to be able to pass nutrients and other substances into and out of the cell limits how big cells can get. The larger a cell is, the more difficult it is for nutrients and gases to move in and out of the cell because the volume is larger than the surface area. Smaller cells can exchange nutrients with the external environment more quickly.

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:

Virulence, the capacity to cause disease, varies markedly among viruses. Some viruses cause lethal disease while others do not. For example, nearly all humans infected with rabies virus develop a disease of the central nervous system which ultimately leads to death. In contrast, most humans are infected with circoviruses with no apparent consequence.

Explanation: One explanation for viral virulence is that it facilitates transmission. However, a comparison of infections caused by two enteric viruses, poliovirus and norovirus, does not support this general view. Both viruses infect the gastrointestinal tract and are spread efficiently among humans by fecal contamination.

Hypothesis: Birds do not spontaneously generate on birdfeeders.

Experimental design:

Obtain two identical birdfeeders and fill them with birdseed of the same brand and type.

Place both birdfeeders in the same location, one on the ground and the other hanging from a tree or pole.

Randomly select a time of day to check the birdfeeders and record the number of birds on each feeder.

Repeat the experiment for a minimum of 7 days to collect sufficient data.

Analyze the data collected and compare the number of birds on each feeder to determine if there is a statistically significant difference.

Control:

The control in this experiment is the birdfeeder on the ground, which serves as a baseline for the number of birds that naturally visit the area.

Variables:

Independent variable: The location of the birdfeeder (ground or hanging).

Dependent variable: The number of birds on each feeder.

Potential confounding variables:

Weather conditions: Wind, rain, and temperature can affect bird behavior and may influence the results.

Time of day: Some birds are more active in the morning or evening, which may impact the number of birds observed.

The type of birdseed used: Different types of birdseed may attract different birds, which could affect the results.

To control for these variables, the experiment should be conducted at the same time of day and in similar weather conditions. The same type of birdseed should be used for both feeders to eliminate differences in bird preference.

If you were to treat sperm precursor cells with an agent that completely destroys microtubules.  It would affect meiosis by: C. Homologous chromosome pairs would not line up at the cell's center, and the rest of meiosis would not proceed normally.

During metaphase I of meiosis, homologous chromosome pairs align along the equator of the cell, also known as the metaphase plate, and microtubules from the centrosomes attach to the kinetochores on each chromosome. The microtubules then pull the homologous chromosomes apart during anaphase I, leading to their separation into two different daughter cells.

If sperm precursor cells were treated with an agent that destroys microtubules, then the homologous chromosomes would not be able to align correctly along the metaphase plate, as the microtubules would not be able to attach to the kinetochores. As a result, the rest of meiosis would not proceed normally, leading to abnormal cell division and the formation of non-viable sperm cells.

Therefore, option C is the correct answer.

The complete question is:

If you were to treat sperm precursor cells with an agent that completely destroys microtubules (and ensures that they don't reform) at the start of metaphase I, how would this affect meiosis?

A.

This would prevent kinetochores from forming on either side of the centrosome during meiosis I.

B.

Meiosis I would be interrupted, but meiosis II would proceed normally, since microtubules are not required during this stage.

C.

Homologous chromosome pairs would not line up at the cell's center, and the rest of meiosis would not proceed normally.

D.

This would only affect the separation of homologous chromosomes during anaphase I, but would not cause any changes to telophase I or subsequent cell division.

Explanation:

The point where the axon terminal synapses with the muscle fiber sarcolemma is called the neuromuscular junction.

The neuromuscular junction (NMJ) is a highly specialized synapse between a motor neuron nerve terminal and its muscle fiber that are responsible for converting electrical impulses generated by the motor neuron into electrical activity in the muscle fibers. On arrival of the motor nerve action potential, calcium enters the presynaptic terminal, which leads to the release of the neurotransmitter acetylcholine (ACh).

ACh crosses the synaptic gap and binds to ACh receptors tightly clustered on the surface of the muscle fiber, this leads to the endplate potential which initiates the muscle action potential that results in muscle contraction.

Mitochondria are found abundantly in the midpiece of the sperm. The midpiece is located just behind the head of the sperm and contains many mitochondria that provide energy for the sperm to swim towards the egg. The egg, on the other hand, contains mitochondria throughout its cytoplasm. This is because the egg needs a large amount of energy to support the early stages of embryonic development, before the zygote can begin to produce its own energy.

During fertilization, the sperm and egg combine to form a zygote. The mitochondria from the sperm are typically destroyed after fertilization, so the zygote relies solely on the mitochondria from the egg for energy production. This is why mitochondrial DNA is inherited solely from the mother in most animals, including humans.

The fluid in the cochlea moves in response to vibrations from the oval window. 25,000 nerve endings are set in action when the fluid travels.

These nerve terminals convert vibrations into electrical impulses, which travel to the brain via the eighth cranial nerve (auditory nerve). It is made up of little hair cells that border the cochlea. These cells convert vibrations into electrical impulses, which sensory nerves carry to the brain.

Mechanical vibrations are transmitted. Hair cells of the Corti organ convert mechanical sound waves into nerve signals. When the basilar membrane, on which the organ of Corti lies, vibrates, they are activated.
