The lipid bilayer membrane of a neuron is impermeable to charged molecules or ions. To enter or exit the neuron, ions must pass through special proteins called ion channels that span the membrane. Ion channels have different configurations: open, closed, and inactive. Some ion channels need to be activated in order to open and allow ions to pass into or out of the cell. Which ion channels are used in the production of electrical signals (Action Potential) in neurons

Answers

Answer:

The correct answer is: in neurons, the most used ion channels in the production of action potentials are the channels that allow fo passage of sodium and potassium.

Explanation:

Neurons must be able to transmit and receive signals in order for the nervous system to operate. Because each neuron has a charged cellular membrane (a voltage differential between the interior and the exterior), the charge of this membrane can vary in response to neurotransmitter molecules generated by other neurons as well as external stimuli. The membrane potential is the difference in total charge between the interior and outside of the cell. This membrane potential exists thanks to the state of ion channels that may or may not allow the passage of certain ions.

A substance called a neurotransmitter allows a neuron to accept input from other neurons. The neuron will transmit the signal to downstream neurons if the input is powerful enough. The opening and shutting of voltage-gated ion channels, which produce a transient reversal of the resting membrane potential to form an action potential, are used to transmit a signal within a neuron (in one direction only, from dendrite to axon terminal). The polarity of an action potential changes across the membrane as it travels down the axon. The signal then activates other neurons once it reaches the axon terminal.

The target neuron is depolarized to its threshold potential (-55 mV) by a stimulation from a sensory cell or another neuron, and Na+ channels in the axon hillock open, initiating an action potential. The neuron totally depolarizes to a membrane potential of around +40 mV after the sodium channels open. As Na+ channels open, the action potential moves along the neuron.

The cell's membrane voltage is "reset" to the resting potential after depolarization is complete. The Na+ channels shut, signaling the start of the refractory phase in the neuron. Voltage-gated K+ channels open at the same moment, allowing K+ to escape the cell. The membrane potential returns to a negative state as K+ ions exit the cell. The cell becomes hyperpolarized when K+ diffuses out of it, resulting in a membrane potential that is lower than the cell's usual resting potential. The sodium channels revert to their resting state at this moment, ready to open again if the membrane potential rises over the threshold potential again.

Mary determined that 5 pollen grains could fit along the diameter of the field of view of her microscope. If each pollen grain has a diameter of 0.3mm what is the diameter in millimeters of the field of view of Mary's microscope
1.5mm
15mm
4.7mm
5.3mm

Answers

Answer:

1.5mm

Explanation:

According to this question, Mary is trying to view 5 pollen grains under her microscope. She found out that the 5 pollen grains each with a diameter of 0.3mm could fit along the diameter of the field of view of her microscope.

This means that the diameter of the field of view of Mary's microscope can be calculated as follows:

Diameter of each pollen × no. of pollen that fit in

= 0.3mm × 5

= 1.5mm

Hence, the diameter of the field of view of Mary's microscope is 1.5mm.

An individual with two different versions of a gene is genetically ____________ . In traits with a simple pattern of inheritance, only the trait conferred by the ____________ form of the gene will be visible. The other form of the gene is ____________ : it confers a trait that is only visible when the individual is genetically ____________ , or has two identical copies of the gene.

Answers

Answer:

heterozygous; dominant; recessive; h.o.mo-zygous

Explanation:

Genetics can be defined as the scientific study of hereditary in living organisms such as humans, animals and plants.

In Genetics, co-dominance can be defined as a phenomenon in which two (2) alleles of the same gene are present in a living organism and both are equally expressed to a degree or simultaneously.

This ultimately implies that, co-dominance is a phenomenon that typically involves the relationship between alleles i.e the two (2) versions of a gene present in living organisms. Also, a single version of a gene expressed by a living organism is referred to as an allele.

Trait can be defined as a distinguishing quality or characteristic of a living thing.

Simply stated, a trait refers to the specific features or characteristics possessed by a living organism. It is essentially transferred from the parent of a living organism to her offspring and as such distinguishes him or her.

Some examples of traits in genetics are colorblindness, handedness, curly hair, height, complexion, weight, hair color, dimples, tongue-roll, etc.

In Genetics, when an individual has two (2) different versions of a gene, he or she is said to be genetically heterozygous.

In traits with a simple pattern of inheritance, only the trait conferred by the dominant form of the gene from the parent organism will be visible in the offspring of a living organism. The other form of the gene is recessive : it confers a trait that is only visible when the individual is genetically , or has two identical copies of the gene.

Match the surface to its respective albedo score. fresh snow soil ocean (high-angle sun) ocean (low-angle sun) 0.95 arrowRight 0.2 arrowRight 0.9 arrowRight 0.05 arrowRight Reset Next

Answers

Answer:

fresh snow → 0.9soil → 0.2ocean (high-angle sun) → 0.05ocean (low-angle sun → 0.95

Explanation:

Albedo is the radiation reflected by the earth´s surface to the universe.

Albedo might be defined as a relation between reflected light from a particle and the incident light. It is the fraction of the incident radiation that is reflected by any object. If the surface is mostly clear and clean, most of the incident radiation is reflected. But if the surface is dark and rugose, most of the incident radiation is absorbed, and the temperature of the absorbing object will increase.

Albedo value is always inferior or equal to one and can be expressed as a percentage. The surface that reflects 100% of the incident light will have an albedo value = 1. But if the surface absorbs all the radiation and does not reflect any percentage, the albedo value = 0. Note: there is no real object that might reflect or absorb 100% of the incident radiation.

The importance of albedo is that it avoids high temperatures on the earth. There are many different surfaces with different albedo values. Global variations in albedo are natural processes due to exogenic and endogenic variations. But to these natural events, we must add all the variations caused by human beings´ actions, which increase greenhouse gases, decreasing albedo, and increasing global warming. The increase of greenhouse gases, such as CO₂, decreases albedo. The same occurs with atmospheric dust due to volcanic eruptions. Additional material interposes between the earth´s surface and the universe, decreasing the energy return to the universe.

Explanation:

The above is the correct answer.

Force = mass x acceleration = mg

⇒ F = mg

where F = 560 N, m = 1000kg

∴ g = F/m = 560/1000 = 0.56

∴ acceleration, g = 0.56m/s² (answer)

Answers

Answer:

C

Explanation:

Natural Selection can cause micro evolution, or a change in allele frequency over time

An allele becomes more common in a population. So, the correct option is (C).

What is an Allele Frequency?

Allele frequency is also known as gene frequency. It is defined as the relative frequency of an allele at a particular locus in a population, expressed as a fraction or percentage. It is the fraction of all chromosomes in the population that carry that allele over the total population or sample size.

It forms the basis of many population and medical genetic studies. Many evolutionary forces change allele frequencies where allele frequencies can be used to trace past evolutionary events.

Allele Frequency is expressed as:

[tex]1 = p^2 + 2pq + q^2[/tex]

p and q each represent the allele frequency of different alleles.

Thus, an allele becomes more common in a population. So, the correct option is (C).

Musculo que tiene las características tanto de musculo esquelético como de musculo liso. Se encuentra en el corazón y sus contracciones son involuntarias

Answers

Answer:

músculo cardíaco

Explanation:

Los 3 tipos de tejido muscular son 1-músculo cardíaco o miocardio (involuntario), 2-músculo liso (involuntario) y 3-músculo esquelético (voluntario). Las células del músculo cardíaco, las cuales son conocidas como 'miocardiocitos', poseen una apariencia estriada y forman la pared del corazón. Los miocardiocitos son alargados, ramificados, y poseen un núcleo central (son células uninucleadas, a diferencia de las células del músculo esquelético, las cuales son multinucleadas). Además, los micardicitos son más cortos (80 a 100 µm) y más anchos (aprox. 15 µm) que las células del músculo esquelético. Los miocardiocitos presentan uniones especializadas conocidas como discos intercalares, los cuales son un tipo de complejo de unión entre los límites de dos cardiomiocitos. En el citoplasma de los cardiomiocitos se encuentran las miofibrillas, las cuales son estructuras contráctililes que les confieren a las células musculares sus propiedades características de contracción y de elasticidad. En estas células (cardiomiocitos) las miofibrillas se disponen de manera longitudininal con un patrón estriado.
