Lidocaine is a topical anesthetic used to treat minor muscular pain and skin irritation. As shown in the diagram below, lidocaine can exist in an ionized state and an nonionized state. According to this diagram, which of the following statements best explains how lidocaine directly exerts its anesthetic effects?
A. lidocaine blocks a neural cell membrane from depolarizing, causing the neuron to be unable to transmit an action potential.
B. lidocaine prevents the release of neurotransmitters from the axon of the transmittinf neuron.
C. lidocaine binds to external surfaces of channel proteins embedded in the neural membrane, which blocks movement of ions into the cell.
D. lidocaine activates sodium channels to open, causinf rapid depolarization of the neuronal membrane.​

Answers

Answer:

A. Lidocaine blocks a neural cell membrane from depolarizing, causing the neuron to be unable to transmit an action potential.

Explanation:

Lidocaine works by blocking the voltage-gated sodium channels in the neuronal membrane, which prevents the depolarization required for the neuron to transmit an action potential. This blockage occurs preferentially in the ionized form of lidocaine, which can bind to the inside of the sodium channels. The nonionized form of lidocaine can more easily penetrate the lipid membrane of the neuron and reach the sodium channels from inside the membrane, where it can then become ionized and block the channels. This results in a local anesthetic effect, as the neuron is unable to transmit signals of pain or discomfort.

8. A ​NONSENSE MUTATION​ occurs when a codon is changed to a STOP codon. Many proteins are thousands of amino acids in length. At the end of the gene, the cell reaches the stop codon. If a codon is changed to STOP, the building of the amino acid terminates and the protein is incomplete.
Why would a Nonsense mutation be less damaging if it occurred at the end of the gene rather than the beginning?

Answers

Nonsense mutations are point mutations that cause an mRNA codon to turn into a stop codon. If the mutation is at the beginning of the gene, it is more damaging because most of the protein is affected. The new molecule is shorter, quite different from the original one, and would not accomplish all its functions.  

What is a nonsense mutation?

When a change occurs in a single base pair, it is known as a point mutation. Points mutations might be either silent, missense, or nonsense.

Nonsense mutations turn the mRNA codon into a stop codon, making the mutated protein reach its end before the original protein.

The length of the new molecule depends on where the mutation occurred.

If the mutation occurs at the beginning it is more damaging than if it occurs at the end.

If the mutation occurs at the end, most of the original protein can be synthesized before reaching the mutation point, getting to be highly similar to the original protein, and getting to accomplish most of its functions.

If the mutation occurs at the beginning of the gene, the new protein is almost entirely different from the original one, very short, and with highly altered functions.

How is genetic variation passed down in asexual reproduction

Answers

In asexual reproduction, genetic variation is not passed down as the offspring are exact genetic copies of the parent. The genetic material of the parent is replicated, and the copies are distributed to the daughter cells without any exchange or recombination of genetic information. This results in a lack of diversity in the offspring and a reduced ability to adapt to changing environments. However, some forms of asexual reproduction, such as budding in yeast or fragmentation in starfish, can occasionally produce genetic variation due to errors in DNA replication or changes in chromosome number.

SOMEONE PLEASE HELP!!!! Draw a diagram a neuron in the midst of conducting a nerve impulse. Your diagram should show changes in ion movement, and changes in internal and external net charge (+ or -) as the impulse is propagated. ​

Answers

During a nerve impulse, neuron undergoes changes in ion movement across its cell membrane.

What is nerve impulse?

Sudden reversal of the electrical charge across membrane of resting neuron is called nerve impulse.

Initially,  neuron has a resting membrane potential of approximately -70 millivolts (mV) with more negatively charged ions inside the neuron compared to outside. When stimulus is received, ion channels open in response, allowing for influx of positively charged sodium ions into neuron. This influx of Na+ ions depolarizes membrane potential, causing  internal net charge to become more positive.

Once the membrane potential reaches certain threshold , voltage-gated ion channels open, causing larger influx of Na+ ions into neuron. This creates an action potential, rapid and transient change in membrane potential where internal net charge becomes more positive and external net charge becomes more negative.

As action potential moves down the axon of neuron, voltage-gated ion channels continue to open and close, causing wave of depolarization followed by repolarization. During repolarization phase, voltage-gated ion channels for K+ open, allowing efflux of K+ ions out of the neuron.

What is speed?

Speed is the rate of change in the position of an object over a period of time. It is measured in various units such as meters per second, miles per hour, and kilometers per hour. Speed is a scalar quantity, which means it has magnitude but no direction. Speed can be thought of as the rate at which an object covers distance. It is the magnitude of the velocity of an object, which is the rate and direction of its motion. Speed is calculated by dividing the distance travelled by the time taken.

The mean speed is determined by taking the sum of all the speeds and dividing it by the number of speeds. Without knowing the individual speeds, it is impossible to calculate the mean speed.

Answers

There are numerous cleanup procedures for oil spills that can have significant environmental consequences, and strategies for mitigating those consequences will vary depending on the approach utilized. Yet, here is an example of a negative influence and a strategy to reduce it:

Negative impact: The use of chemical dispersants to break up the oil slick can be harmful to marine life and ecosystems. Dispersants can also disperse oil throughout the water column, making cleanup more difficult.

Solution: One option to lessen the harmful effects of dispersants is to limit their use and employ them only in regions where oil is unlikely to reach delicate habitats or when other cleanup methods are ineffective. Furthermore, employing more natural, biodegradable dispersants rather than synthetic ones can lessen the total environmental impact. Finally, utilizing dispersants in conjunction with mechanical measures such as booms and skimmers can aid in the containment and removal of scattered oil.

E. each daughter cell receives exactly half the genetic information in the parent cell.

Answers

Answer:

C. each daughter cell receives a nearly perfect copy of the parent cell's genetic information.

Explanation:

During mitosis, the genetic material (DNA) is replicated and then divided equally between the two daughter cells, ensuring that each cell receives an identical set of chromosomes. Cytokinesis then physically separates the two cells. While some random mutations can occur during DNA replication, the overall amount and content of genetic information in each daughter cell is almost identical to the parent cell. Option A is incorrect because it suggests that the genetic information is altered, which is not necessarily true. Option B is incorrect because it suggests that the division of genetic material is random, which is not the case during mitosis. Option D and E are also incorrect.

Answers

Polystyrene is a type of plastic made up of long-chain molecules of styrene monomers, each of which consists of a benzene ring with two attached side chains.

What is monomers?

Monomers are the basic building blocks of many substances. They are small molecules that can be connected together in a variety of ways to form larger molecules. Monomers can be either organic or inorganic, and some examples of organic monomers include carbohydrates, proteins, and nucleic acids.

Answer 1: Polystyrene is a type of plastic made up of long-chain molecules of styrene monomers, each of which consists of a benzene ring with two attached side chains. These molecules are arranged in the sheet in a random, tangled pattern, held together by weak Van der Waals forces. This arrangement is necessary to ensure the flexibility and strength of the sheet.

Answer 2: When a sheet of polystyrene is heated, the molecules of the plastic become more active and start to move around. This movement causes them to become more tightly packed together, resulting in the sheet shrinking in size. At the same time, the sheet's structure becomes more rigid as the intermolecular forces between the molecules increase.

Answer 3: Scientists have used the shrinking property of polystyrene sheets in nanotechnology to create nano-sized structures such as nanotubes and nanowires. By shrinking the polystyrene sheets down to the nanoscale, scientists can better manipulate the material to create these structures. This has allowed them to create nanoscale devices with improved electrical, optical, and mechanical properties.

Characteristics of Electromagnetic Spectrum
Analog vs. Digital Signals
Multiple frequencies of the electromagnetic spectrum can carry communication signals and mass amounts of information. In general, signals sent using higher frequencies of the electromagnetic spectrum travel shorter distances but have a higher data-carrying capacity. This physical characteristic of electromagnetic waves limits the range and availability of frequencies for sending information.

The electromagnetic spectrum is a limited resource. Since electromagnetic waves move outward in all directions, wave transmitters need to be focused to transmit their signals to a single specified location. Likewise, wave receivers can be focused to maximize signal reception from a particular location. However, the receiving antenna may still detect unintended signals that can interfere with reception.

To avoid signal interference problems, multiple users cannot transmit radio signals at the same frequencies, at the same time, and in the same direction. The spectrum is scarce; at any given time and place, one use of a frequency prevents it from being used by others in the same location. As soon as one user stops transmitting signals over a portion of the spectrum, another user can immediately re-use it.

There are two important types of signal transmissions to understand: analog and digital.

wave that rises and falls
Analog wave
Analog signal transmission information (sound, video, or data) travels in a continuous wave whose strength and frequency change depending on the amount of data being submitted.

Travels in a continuous wave
Strength and frequency vary
wave that rises and falls but is square instead of wavy
Digital wave
Digital signal transmission information is converted to ones and zeros which are formatted and sent as electrical pulses. Advantages of using digital signals include greater accuracy, noise reduction (unwanted signals) and an increased capacity for sending information.

Answers

In summary, the electromagnetic spectrum is a limited resource that is used for a variety of communication needs.

What is electromagnetic spectrum?

The electromagnetic spectrum is the range of all types of electromagnetic radiation. It is made up of different types of radiation, such as radio waves, microwaves, infrared radiation, visible light, ultraviolet radiation, X-rays and gamma rays. Each type of radiation has different characteristics, such as wavelength, frequency, and energy. All types of electromagnetic radiation are affected by the electromagnetic force, which is a type of force between objects that have an electric charge. Electromagnetic radiation is used in many different ways, such as to provide communication, to detect objects, and to provide energy.

The spectrum contains multiple frequencies that are used for sending information, either in analog or digital form. Analog signals travel in a continuous wave, while digital signals are converted to ones and zeros and sent as electrical pulses.
