generally, how do sensory neurons encode stimulus intensity of higher and lower intensity? what is the dynamic range of a sensory neuron? what defines the threshold intensity of a neuron? how does range fractionation improve the dynamic range? what is the difference between population coding and place coding

Answers

Answer 1

Sensory neurons encode stimulus intensity of higher and lower intensity by increasing firing rate and by recruitment of additional sensory neurons.

Sensory neurons encode stimulus intensity in different ways depending on the modality. However, in general, sensory neurons can encode stimulus intensity of higher and lower intensity through the following mechanisms:

Increased firing rate: As the intensity of a stimulus increases, sensory neurons can increase their firing rate. Higher intensity stimuli lead to more frequent action potentials in the sensory neuron, resulting in a higher overall firing rate.Recruitment of additional sensory neurons: For higher intensity stimuli, sensory systems can recruit additional sensory neurons to respond to the stimulus. This increases the overall population response and enhances the encoding of stimulus intensity.

The dynamic range of a sensory neuron refers to the range of stimulus intensities that the neuron can detect and respond to. It encompasses the minimum stimulus intensity that can activate the neuron and the maximum stimulus intensity that can be detected before the neuron reaches saturation.

The threshold intensity of a neuron is the minimum stimulus intensity required to elicit a response from the neuron. It represents the point at which the sensory neuron becomes activated and starts to transmit signals.

Range fractionation is a mechanism that improves the dynamic range of sensory neurons. It involves distributing the sensory neurons across a range of threshold sensitivities. By having sensory neurons with different threshold sensitivities, the population as a whole can effectively encode a wide range of stimulus intensities. Each sensory neuron within the population is specialized to respond optimally within a particular range of stimulus intensities, thereby expanding the dynamic range of the overall sensory system.

Population coding and place coding are two different strategies used by sensory systems to encode stimulus information:

Population coding: In population coding, information about a stimulus is encoded by the combined activity of a population of neurons. Each neuron within the population contributes to the overall representation of the stimulus. The pattern of activity across the population of neurons provides information about the stimulus attributes, such as its intensity or location. The relative activity levels and firing rates of different neurons within the population contribute to the encoding of specific stimulus features.

Place coding: Place coding, also known as labeled-line coding, involves the encoding of stimulus information based on the specific location or identity of the activated sensory neurons. Each sensory neuron is tuned to respond to a specific feature or modality of the stimulus. The specific neuron or group of neurons that is activated provides information about the identity or location of the stimulus. For example, in the auditory system, different neurons respond selectively to specific sound frequencies, allowing for the encoding of different frequencies or pitches.

Which nitrogenous waste removed by the kidney is produced by the breakdown of nucleic acids?

Answers

Answer:

Nitrogenous waste removed by the kidney is produced by the breakdown of nucleic acids is uric acid.

Explanation:

Purine nucleotides are broken down metabolically into uric acid, which is a typical part of urine. Increased levels of uric acid into the blood may cause arthritis and are linked to other illnesses including those of diabetes and the development of kidney stones made of ammonium acid urate.  Nitrogenous wastes like Urea as well as uric acid are indeed the primary nitrogenous waste products. Whereas uric acid is produced by the breakdown of nucleotides, urea is produced by the breakdown of amino acids. The metabolism of amino acids produces urea, which is the body's primary nitrogen-containing- containing waste product. Purine metabolism generates uric acid as a byproduct. Because of the absence of uricase, a crucial enzyme that transforms uric acid into water-soluble compound active ingredients, high levels of blood uric acid have the potential to remain in humans as well as relatively high primates.

How will you find the valency of chlorine, sulphur and magnesium

Answers

Answer:

Explanation:

ANSWER

If the number of electrons in the outermost shell of an atom of an element is less than or equal to 4, then the valency of an element is equal to the number of electrons in the outermost shell.  

If it is greater than 4 then, the valance is determined by subtracting the outermost shell of electrons from 8.

The electrons in Cl, S, and Mg are 2,8,7 ; 2,8,6 ; 2,8,2  

Hence the valency of Cl, S, and Mg are 1, 2, 2 respectively.

Answer:

Chlorine has 7 valence electrons

Magnesium has 2 valence electrons

Sulphur has 6 Valence electrons

Explanation:

We can find how many valence electrons by looking at the periodic table. For instance chlorine is a halogen and therefore has 7 valence electrons as it is in group 17. Magnesium is in group 2 so therefore has 2 valence electrons.

Sulphur is in group 16 and therefore has 6 valence electrons.

If the group has double digits I.e 16 like sulphur we only look at the second digit i.e. 6 as we can't have more than 8 valence electrons.

Active transport is the pumping through a membrane against a concentration gradient of molecules or ions. It needs energy and a combination of transmembrane proteins known as a transporter.

There are two types of active transport mechanisms. Primary active transport directly moves molecules across a membrane against their gradient using a source of chemical energy, such as ATP. On the other hand, secondary active transport, also known as cotransport, leverages the electrochemical gradient created by active transport as a source of energy to move molecules against their gradient, negating the need for a chemical energy source like ATP. The transport procedure is regarded as an example of primary active transport because it utilizes ATP as an energy source.

Each sister chromatid uses a protein complex termed the kinetochore to connect to spindle microtubules at the centromere.

Sister chromatids are bound to one another during mitotic prometaphase, but why?

Cohesion is necessary for sister chromatids to stay together during mitosis and meiosis until separation is about to occur at anaphase. Cohesins are multiprotein component complexes that help create cohesion during DNA replication prior to mitosis and meiosis.

During prometaphase, where do microtubules bind to sister chromatids?kinetochores

The production of a protein structure known as a kinetochore around the centromere, the central region connecting the sister chromatids, is another significant process that occurs during prometaphase.

The correct order is:

Induction of lytic cycle Phage DNA circularizes and detached from host DNA A portion of host DNA is exchanged for phage DNA Detached DNA replicates Phage replication is completed and cell lyses

The correct sequence of steps that leads to the production of both normal temperate phage and defective phage particles carrying host genetic material for specialized transduction events is as follows:

Induction of lytic cycle: The temperate phage switches from a lysogenic cycle to a lytic cycle, usually triggered by specific environmental conditions or signals.Phage DNA circularizes and detaches from host DNA: The phage DNA separates from the host DNA and forms a circular molecule.A portion of host DNA is exchanged for phage DNA: During the packaging process, when the phage DNA is packaged into the phage capsid, some fragments of the host DNA can mistakenly be incorporated into the phage particle.Detached DNA replicates: The circular phage DNA and the incorporated host DNA replicate inside the phage particle.Phage replication is completed and cell lyses: The phage DNA is replicated, and new phage particles are assembled. Eventually, the infected cell is lysed (bursts open), releasing the phage particles, which can infect new host cells.

It's important to note that specialized transduction occurs during step 3 when fragments of host DNA are mistakenly incorporated into the phage particle. This allows for the transfer of host genetic material to recipient cells during subsequent infection.
