Look at the graph and explain what is happening at each of the points labelled A to E. (5)

Answer:

True

Explanation:

The given statement "The splanchnic nerves contain preganglionic axons of the sympathetic nervous system" is true because these axons synapse with postganglionic neurons in ganglia located near or within the organs they innervate.

The splanchnic nerves are a group of nerves that originate in the thoracic and lumbar regions of the spinal cord and innervate the viscera. They are part of the sympathetic nervous system, which is responsible for the "fight-or-flight" response.

The preganglionic axons of the sympathetic nervous system are short axons that originate in the spinal cord and synapse with postganglionic neurons in ganglia located near or within the organs they innervate. The splanchnic nerves contain the preganglionic axons that innervate the viscera of the abdomen and pelvis.

The postganglionic axons of the sympathetic nervous system are longer axons that originate in the ganglia and innervate the organs they innervate. The postganglionic axons of the splanchnic nerves release the neurotransmitter norepinephrine, which activates the sympathetic receptors on the organs they innervate.

Hunting has not directly contributed to land loss on the Isle de Jean Charles.

What is Leaves?

Leaves are the main organs of photosynthesis in most plants. They are typically flat, thin and come in a wide variety of shapes and sizes. The primary function of leaves is to produce food for the plant through the process of photosynthesis. In this process, the leaves absorb light energy from the sun and use it to convert carbon dioxide and water into simple sugars, which can be used by the plant for energy.

Levees, hurricanes, and dredging have all played a role in the erosion and subsidence of the island, which has led to the loss of land over time. Hunting, on the other hand, is not directly related to land loss but may have indirect effects on the ecosystem and wildlife populations on the island.

As individuals, we use various resources on a day-to-day basis, including fuel, electricity, food, water, and other resources. In the long-term, our usage can have a significant impact on the natural habitats surrounding us. The more we use resources, the more we contribute to the depletion of natural resources, which in turn can lead to the destruction of habitats.

Garbage disposal is another significant factor that affects the environment. Most of the garbage that we produce is sent to landfills, which not only takes up a lot of space but also pollutes the environment. The garbage disposal process, such as incineration, can also cause air pollution and release harmful gases into the atmosphere.

Driving, particularly long distances, can significantly impact the environment. The more we drive, the more fuel we consume, which in turn contributes to air pollution and greenhouse gas emissions, leading to global warming and climate change. Similarly, buying food also has an environmental impact. The transportation of food products from one place to another contributes to air pollution, and the use of fertilizers and pesticides in agriculture can contaminate soil and water resources.

All of these factors have a significant effect on the natural environment. The depletion of natural resources, the pollution of air and water, and the destruction of habitats all have significant impacts on the planet's biodiversity and ecosystem.

To lessen the effect, we can adopt more environmentally friendly practices. We can reduce our usage of resources by conserving energy, reducing water consumption, and using public transportation or carpooling. We can also reduce our impact on the environment by reducing the amount of waste we produce, recycling, and properly disposing of hazardous waste. Additionally, we can support local agriculture, which can reduce the transportation of food products and promote sustainable farming practices. By taking these steps, we can help preserve natural habitats and contribute to a healthier and more sustainable planet.

The Devil's Hole pupfish has evolved a behavior described as "paradoxical anaerobism" as a result of adapting to a lack of oxygen in its habitat.

The correct answer is: A.

HABITAT: Having evolved to live within dry regions, deserts pupfish are capable of withstand conditions such as daily temperature changes of up to forty-five degrees Celsius, water temperatures around 120 degrees Celsius, extremely low concentrations of oxygen, salinity levels over twice as much of the ocean, and water temperatures above 110 degrees Fahrenheit.

Warm, salinized waters or salt streams are where they live, which would quickly kill a trout. For example, a Salt Creek pupfish can survive in seawater that is three times as salty. In Monument Valley National Park, they are plainly visible from a boardwalk.

A gene is a unit of heredity that is responsible for the inheritance of a particular trait from parents to offspring.

The four principles of natural selection are:

Variation: Individuals within a population exhibit differences in their traits or characteristics.

Inheritance: Some of these variations are passed from parents to their offspring.

Selection: Individuals with certain variations that make them better adapted to their environment are more likely to survive and reproduce.

Time: Over many generations, the frequency of advantageous traits increases within the population, leading to evolutionary change.

A species is a group of individuals with similar physical and genetic characteristics that can interbreed and produce fertile offspring.

Genetic drift is the movement of alleles from one population to another due to chance events, such as the migration of individuals.

The term that refers to the evolutionary history of a species is "phylogeny".

Phylogeny is the study of the evolutionary relationships among organisms and their history of descent from a common ancestor. It is based on the comparison of anatomical, genetic, and other characteristics among different species.

Answer: Tends to increase inbreeding among the species of plant being pollinated.

Explanation:

Animal-mediated pollination, where animals such as insects, birds, or bats transfer pollen from one flower to another, tends to increase inbreeding among the species of plant being pollinated. This is because animals often visit multiple flowers of the same plant or closely related plants in close proximity, leading to a higher likelihood of pollen being transferred between closely related individuals. This can result in reduced genetic diversity and increased inbreeding among the plant population, which may have both positive and negative effects depending on the specific species and ecological context.

The other options provided do not accurately reflect the characteristics of animal-mediated pollination. For example, animal-mediated pollination is actually considered to be a more efficient mode of pollination compared to wind pollination, as it allows for targeted and controlled transfer of pollen between flowers, increasing the chances of successful pollination and reproduction. Animal-mediated pollination is also not limited to high plant population density or specific plant groups such as angiosperms, and there is no evidence to suggest that it has decreased diversification among insects and flowering plants.

Central nervous system

Peripheral nervous system

The nervous system is the complex network of nerve cells and fibers that transmits signals between different parts of the body. It is divided into two main parts: the central nervous system (CNS) and the peripheral nervous system (PNS).

The central nervous system (CNS) includes the brain and spinal cord. It is responsible for receiving and interpreting sensory information from the PNS, and for generating motor commands that are sent out to the PNS to control the body's muscles and organs.

The peripheral nervous system (PNS) consists of all the nerves and ganglia outside of the brain and spinal cord. It is further divided into the somatic nervous system and the autonomic nervous system. The somatic nervous system controls voluntary movements and transmits sensory information to the CNS, while the autonomic nervous system controls involuntary functions such as heart rate, digestion, and breathing.

Answer:

Mitochondrial inheritance: It follows a different pattern than classical Mendelian inheritance because it is not controlled by genes on the chromosomes in the cell nucleus. Instead, all offspring of a mother with a mitochondrial DNA mutation will inherit that mutation, but only females will pass it on to their offspring. This is because only the egg cell, not the sperm cell, contributes mitochondria to the next generation.

Epigenetic inheritance: Epigenetic modifications, such as DNA methylation and histone modification, can affect gene expression and be passed on from one generation to the next. This type of inheritance does not involve changes in the DNA sequence but rather changes in the way that genes are expressed.

Genomic imprinting: Some genes are expressed differently depending on whether they were inherited from the mother or the father. This is because certain genes are silenced or activated based on their parent of origin, and this pattern of gene expression is maintained throughout the individual's life.

Gene conversion: During meiosis, some DNA molecules can undergo a process called gene conversion, which involves the replacement of one allele with another, resulting in offspring that have a different genetic makeup than expected based on the parental genotypes.

Answer:

So, you need to save approximately $258.60 per month to fund your emergency fund within a year based on the given information.

Explanation:

Let's break down the steps to calculate the amount you need to save per month to fund the emergency fund:

Step 1: Calculate your total deductions

Your deductions include FICA (7.65%), federal tax withholding (12.3%), and state tax withholding (6.2%). To calculate the total deductions, we add these percentages:

Total deductions = FICA + federal tax withholding + state tax withholding

Total deductions = 7.65% + 12.3% + 6.2%

Total deductions = 26.15%

Step 2: Calculate your net income per hour

Your net income per hour is the hourly rate minus the total deductions:

Net income per hour = Hourly rate - Total deductions

Net income per hour = $17.50/hr - 26.15%

Net income per hour = $17.50/hr - $4.57/hr

Net income per hour = $12.93/hr

Step 3: Calculate your monthly realized income

Your monthly realized income is the net income per hour multiplied by the number of hours you work per week and the number of weeks in a month:

Monthly realized income = Net income per hour x Number of hours per week x Number of weeks per month

Monthly realized income = $12.93/hr x 40 hr/wk x 4 wk/month

Monthly realized income = $2,068.80/month

Step 4: Calculate your housing and fixed expenses

Your housing and fixed expenses are 30% of your realized income per month:

Housing and fixed expenses = 30% x Monthly realized income

Housing and fixed expenses = 30% x $2,068.80

Housing and fixed expenses = $620.64/month

Step 5: Calculate the total amount needed for the emergency fund

You want to save 5 months' worth of expenses in an emergency fund within a year. So, the total amount needed for the emergency fund is:

Total amount needed for emergency fund = 5 x Housing and fixed expenses

Total amount needed for emergency fund = 5 x $620.64

Total amount needed for emergency fund = $3,103.20

Step 6: Calculate the amount to save per month

To calculate the amount you need to save per month to fund the emergency fund, divide the total amount needed by the number of months in a year:

Amount to save per month = Total amount needed for emergency fund / Number of months in a year

Amount to save per month = $3,103.20 / 12

Amount to save per month ≈ $258.60

So, you need to save approximately $258.60 per month to fund your emergency fund within a year based on the given information.

Since the genotype ss is the only one that produces the entire margin phenotype, the chance of an offspring having entire leaves is 50% (1 out of 2 possible genotypes: ss or Ss/sS).

An allele is a variant form of a gene that can determine a specific trait or characteristic. Genes are located on chromosomes and can have multiple alleles, which can be dominant, recessive, or codominant. Alleles can be inherited from both parents and can interact with other alleles to determine the phenotype of an organism. For example, the gene for eye color in humans has several alleles, including brown, blue, and green.

The offspring will have a 50% chance of having entire leaves.

When the heterozygous (Ss) and homozygous dominant (SS) plants are crossed, their offspring will inherit one allele from each parent. The possible combinations of alleles are: SS, Ss, and sS (which is the same as Ss).

The genotype SS and Ss both have the dominant allele for serrate margins, while the genotype ss has the recessive allele for entire margins.
