Once the threshold voltage triggers an action potential, what causes action potentials to be generated?
a. Lons channels are opened and positive ions diffuse into the cell.
b. Lons channels are opened and negative ions diffuse into the cell.
c. Lons channels are opened and positive ions diffuse out of the cell.
d. Lons channels are opened and negative ions diffuse out of the cell. ​

Answers

Answer 1

Option A . Lons channels are opened and positive ions diffuse into the cell is the correct answer because:

When the threshold voltage is reached, ion channels in the cell membrane open, allowing positive ions to flow into the cell, leading to depolarization and the generation of an action potential. This process is known as sodium influx.
 Once the threshold voltage triggers an action potential, what causes action potentials to be generated is option (a): Ion channels are opened and positive ions diffuse into the cell. This influx of positive ions leads to a change in membrane potential, propagating the action potential along the neuron.

In the early 1700s, a small religious group know as the German Baptist Brethren left Europe to settle in the eastern part of Pennsylvania. The orginal group of 50 families grew to 58,000 people by the late 1800's. In 1882, a part of the group split off as a result of differences in accepting modern machinery and marriage outside of their group. This Old Order isolated themselves from the other group and other people. In the 1950's a study was done to compare the Old Order to the original West German population and the neighboring population. Blood samples were taken from people in all 3 areas and blood typing tests were preformed.

What would be the most likely reason that the scientist did not test the other half of the German Brethren that adopted more modern ways?

A. The groups' allele frequencies would most likely be affected through the marriage of others that were not part of the orginal group.
B. The distance between the Old Order and the group they left was not far enough to cause any changes in allele frequencies.
C. The Old Order did not have any genetic similariteis with the original group, so there was no need to test them.
D. This group had allele frequencies that were not diverse enough for the study.

What is reason that scientist did not test other half of the German Brethren that adopted more modern ways?

When two populations mate, then resulting offspring carry a mix of the genetic information from both populations, and over time, this can cause changes in allele frequencies of the population.

In the case of the German Baptist Brethren, group that adopted modern ways would have likely intermarried with people outside of their original community, which would have introduced new genetic material and changed allele frequencies of population. This would have made it difficult to compare genetic makeup of modern group to original West German population or to the Old Order group that had remained isolated.

What is the relationship between species diversity and ecosystem resilience?

Answers

Species diversity is an important factor in the resilience of an ecosystem. The more diverse the species in an ecosystem, the greater the ability of the ecosystem to withstand changes in the environment such as changes in temperature, food supply, and water quality.

A diverse species mix provides a greater variety of organisms that can fill different roles in the ecosystem, allowing the ecosystem to adapt more easily to changing conditions. Diverse species also provide a greater number of predators and prey, which helps to maintain a balance between populations.

With a greater number of species, there is also a greater variety of genetic material, which can help the ecosystem to evolve and adapt more quickly to new conditions. The greater the species diversity, the more resilient the ecosystem will be.

a substance produced by stomach cells that is needed for absorption of vitamin b12 is group of answer choices intrinsic factor. r-protein. mfp. transferocobalamin.

Answers

A substance produced by stomach cells that is needed for the absorption of vitamin B12 is intrinsic factor.

Intrinsic factor is a glycoprotein that is secreted by the parietal cells in the stomach lining. It plays a crucial role in the absorption of vitamin B12, which is necessary for the normal functioning of the nervous system and the production of red blood cells.

Vitamin B12 is found in animal products such as meat, fish, and dairy, and is bound to protein. In order for the body to absorb it, it must first be released from the protein by stomach acid and then bind to intrinsic factor, which is produced by the stomach cells.

The complex of vitamin B12 and intrinsic factor is then transported to the small intestine, where it is absorbed by the body.

Without intrinsic factor, vitamin B12 cannot be absorbed by the body, leading to a deficiency. This deficiency can result in a variety of symptoms, including anemia, fatigue, weakness, and nerve damage.

Intrinsic factor deficiency is most commonly seen in individuals with pernicious anemia, an autoimmune disease that affects the stomach lining and impairs the production of intrinsic factor.

What determines which traits will be passed on to the next generation in the greatest frequency?.

Answers

The passing on of traits to the next generation is determined by genetics, specifically the inheritance of genes from parents to their offspring.

Genes are segments of DNA that encode for specific traits, such as eye color or height. The frequency of inheritance for a particular trait depends on whether it is dominant or recessive, as well as the specific alleles (variants of a gene) inherited from each parent.

Dominant alleles will express their corresponding trait in individuals who inherit even one copy, while recessive alleles require two copies to express the trait. Additionally, the likelihood of inheriting a particular allele depends on the frequency of that allele in the population.

In summary, the frequency of inheritance for a particular trait is determined by the inheritance of specific alleles from parents, as well as the dominance or recessiveness of those alleles and their frequency in the population.

What five factors cause people to evaluate risk irrationally?

Answers

The five factors that can cause people to evaluate risk irrationally are: Affect Heuristic, Optimism Bias, Availability Heuristic, Confirmation Bias, Herding Behavior.

There are several factors that can lead people to evaluate risk irrationally. First, emotions can play a significant role in how people perceive risk. Fear, anxiety, and anger can all cause people to overestimate the likelihood of negative outcomes and make irrational decisions. Second, cognitive biases can also influence risk assessment.

Confirmation bias, for example, can cause people to seek out information that confirms their existing beliefs, leading them to ignore or downplay contradictory evidence. Third, people often rely on heuristics, or mental shortcuts, when making decisions about risk. These shortcuts can be useful in some situations, but they can also lead to errors in judgment. Fourth, social influences can also affect how people evaluate risk.

Answers

The correct statement about the immune system is "Eosinophils specifically protect body cells against attack by parasites." The correct answer is option e.

Eosinophils are a type of white blood cell that plays an important role in the immune system's response to parasitic infections. They are attracted to sites of infection by chemicals released by other cells in response to parasites.

Once they reach the infected site, eosinophils release toxic substances that damage the parasite and help to protect the host cell from further damage.

Recombination of genes to produce functional B-cell receptors occurs during the development of B-cells in the bone marrow, not immediately after exposure to antigen. Helper T-cells bind to antigens presented by specialized cells called antigen-presenting cells, not most cells in the body.

Allelic and genotypic frequencies remain the same through generations in a population that is in H-W equilibrium. Frequency of dominant allele: 0.99. Frequency of recessive allele: 0.01. % homozygous dominant: 98%. % heterozygous: 2%. % homozygous recessive: 0.01%.

What is Hardy-Weinberg equilibrium?

The Hardy-Weinberg equilibrium is a theory that states that the allelic and genotypic frequencies in a population in equilibrium remain the same generation after generation.

Populations in H-W equilibrium are not evolving.

Assuming a diallelic gene,

The frequency of the dominant allele p(X) is pThe frequency of the recessive allele p(x) is q

The addition of the allelic frequencies equals 1

p + q = 1.

The genotypic frequencies after one generation are

p² (Homozygous dominant genotypic frequency), 2pq (Heterozygous genotypic frequency), q² (Homozygous recessive genotypic frequency).

The sum of genotypic frequencies equals 1

p² + 2pq + q² = 1

In the exposed example, the frequency of the homozygous recessive genotype is given.

frequency of the homozygous recessive genotype

q² = 1/10000 = 0.0001

From this information, we can get the frequency of the recessive allele by taking the root square of the value.

recessive allele frequency

p² = 0.0001

p = √0.0001

p = 0.01

Now, we can clear the equation p + q = 1 and the get recessive allele frequency.

dominant allele frequency

p + q = 1

p  + 0.01 = 1

p = 1 - 0.01

p = 0.99

Now, we can get the frequency of the homozygous dominant genotype and the heterozygous one.

frequency of the homozygous dominant genotype

p = 0.99

p² = 0.99²

p² = 0.98

frequency of the heterozygous genotype

2pq = 2 x 0.99 x 0.01

2pq = 0.019

p² + 2pq + q² = 1

0.98 + 0.02 + 0.0001 = 1

Answers

A small amount of vasodilation in an arteriole prompts Slight decrease in resistance therefore the correct option is D.

Vasodilation refers to the enlargement of a blood vessel, due to relaxation of its smooth muscle cells. This can be caused by several factors, such as hormones like adrenaline, chemical mediators like nitric oxide, and even stretching of the vessel itself.

When an arteriole undergoes vasodilation, it results in a decrease in resistance across the arteriole wall. As a result, blood flow through the artery is increased. However, this increase in flow is typically accompanied by a slight increase in resistance due to decreased vascular tone and less efficient flow through the artery.

Answers

Silent or missense mutations are types of small-scale mutations that can occur within a DNA sequence. The correct option is c. a single nucleotide is substituted with no effect on the amino acid sequence

These mutations involve changes to a single nucleotide in the DNA, which can result in a change in the corresponding amino acid during protein synthesis.

A silent mutation occurs when a single nucleotide is substituted with no effect on the amino acid sequence. This means that the substitution does not alter the resulting protein or its function, and the mutation is considered neutral. In contrast, a missense mutation occurs when the substitution of a single nucleotide results in the incorporation of the wrong amino acid into the protein sequence.

This can lead to changes in the protein structure and function, potentially causing disease or other negative effects. Both silent and missense mutations can occur naturally as part of genetic variation or as a result of external factors such as exposure to mutagens. Understanding the effects of these types of mutations is important in fields such as genetics, evolutionary biology, and medicine.

Specific and latent heat of water influence land-sea breeze systems by causing temperature differences, leading to air pressure changes and wind circulation.

The specific and latent heat of water play a vital role in the formation of land-sea breeze systems. During the day, land heats up faster than water due to its lower specific heat capacity, creating a temperature difference.

This results in a pressure gradient, causing air to flow from the sea to the land as a sea breeze.

Answers

While measuring as many body traits as possible to determine the key trait for surviving a drought in ground finches may appear to be a good idea, it is better to focus on specific traits that are known to be important for survival in dry conditions.

When going to measure natural selection on morphology in a ground finch (geospiza fortis), it may seem like a good research strategy to measure as many body traits as possible to determine which trait is most important for survival during a drought. However, this approach could be time-consuming, costly, and may not provide the best results. Instead, a wise researcher should focus on specific traits that are known to be important for survival in dry conditions, such as beak size and shape, which can affect a bird's ability to feed on specific types of seeds.

By focusing on a specific trait, a researcher can also gain a better understanding of the ecological factors that drive selection in the population. This approach would allow for more precise predictions and could lead to a better understanding of how natural selection operates in this species. Furthermore, this approach could reduce the number of individuals required for the study, which would be important for conserving endangered populations.

In conclusion, while it may seem like a good idea to measure as many body traits as possible to determine the key trait for surviving a drought in ground finches, it is better to focus on specific traits that are known to be important for survival in dry conditions.

Why does Chad compare Mr. Jung to theInvisible Man? 6) Mary sold $192 worth of greeting cards. If she received 25% commission on her salenow much commission did she earn? According to the word entry, how many definitions are there for the word syllablea.-2b.-1c.-3 16. a solution contains 15. 0 g of naoh in 115. 0 ml of h20. the molarity would be:(1l = 1000 ml) n^2 - 5n + 6, n^2 - 4n+ 4 I need help, i know the answer may possibly be (n-3)(n-2)^2 factor it, an di need steps. Write a brief summary of paragraph 7 through 21 of the Nobel speech [1 point) The following table gives values of the differentiable function y = f(x). 012345678910 123-4.21-1-2135 Estimate the x-values of critical points of (x) on the interval 0 < x < 10. Classity each critical point as a local maximum, local minimum, or neither Enter your critical points as comma-separated xvalue, classification pairs. For example, if you found the critical points x = -2 and x = 3, and that the first was a local minimum and the second nother a minimum nor a maximum, you should enter (-2,min), (3,neither). Enter none if they are no critica/ points) critical points and classifications Now assume that the table gives values of the continuous function y = f'(x) (instead of F(x)). Estimate and classify critical points of the function f(x) critical points and classifications: Computer calculation speeds are usually measured in nanoseconds. A nanosecond is 0. 000000001 seconds. Which choice expresses this very small number using a negative power of 10?. 10-8B. 10-910-10D10 11 Find the divergence of each of the following vector fields at all points where they are defined. div ( (2x2 - sin(xz)) i + 5j - (sin(xz)) k) = _____ Which equation can be used to solve for x Factor the expression. x^2-12x-45 4.68 steam enters a turbine in a vapor power plant operating at steady state at 560c, 80 bar, and exits as a saturated vapor at 8 kpa. the turbine operates adiabatically, and the power developed is 9.43 kw. the steam leaving the turbine enters a condenser heat exchanger, where it is condensed to saturated liquid at 8 kpa through heat transfer to cooling water passing through the condenser as a separate stream. the cooling water enters at 18c and exits at 36c with negligible change in pressure. ignoring kinetic and potential energy effects and stray heat transfer at the outer surface of the condenser, determine the mass flow rate of cooling water required, in kg/s.
