The half-life of carbon-14 is about 5700 years. If you left those 100 carbon-14 atoms to sit around for 5700 years, how many would you expect to decay during that time?
Answers
Answer:
50 atoms of carbon-14
Explanation:
From the question given above, the following data were obtained:
Original amount (N₀) = 100 atoms
Half-life (t½) = 5700 years
Time (t) = 5700 years
Amount that decay =?
Next, we shall determine the number of half-lives that has elapse. This can be obtained illustrated below:
Half-life (t½) = 5700 years
Time (t) = 5700 years
Number of half-lives (n) =?
n = t / t½
n = 5700 / 5700
n = 1
Next, we shall determine the amount remaining. This can be obtained as follow:
Original amount (N₀) = 100 atoms
Number of half-lives (n) = 1
Amount remaining (N) =?
N = 1/2ⁿ × N₀
N = 1/2¹ × 100
N = 1/2 × 100
N = 50 atoms
Finally, we shall determine the amount that decayed as follow:
Original amount (N₀) = 100 atoms
Amount remaining (N) = 50 atoms
Amount that decay =?
Amount that decay = N₀ – N
Amount that decay = 100 – 50
Amount that decay = 50 atoms
Therefore, 50 atoms of carbon-14 have decayed during the time.

What are two tools that you can use to help you better use or understand large amounts of data in a spreadsheet? Your discussion should include the tool, how it functions, and how it makes the data easier to use and understand.
Answers
When working with large amounts of data in a spreadsheet, two tools that can greatly aid in understanding and manipulating the data are filters and pivot tables.
How to explain the informationFilters allow you to selectively display specific data based on criteria you define. When applied to a column or multiple columns in a spreadsheet, filters hide rows that do not meet the specified conditions, making it easier to focus on the data that is relevant to your analysis.
Filtering by a single criterion
You can apply filters to individual columns and specify conditions such as equal to, not equal to, greater than, less than, etc.
Filtering by multiple criteria: You can also apply filters to multiple columns simultaneously, allowing you to create more complex conditions.

Can Pluto actually be the next Earth? If it wasn't so cold?
Answers
Note that even if Pluto was not cold, it lacks the essential conditions necessary for it to become the next Earth.
How is this so?Pluto cannot be the next Earth, even if it wasn't cold. There are several reasons for this:
1. Size and Composition - Pluto is much smaller than Earth and is composed primarily of rock and ice, whereas Earth has a diverse composition and a solid surface suitable for life.
2. Atmosphere - Pluto has a thin and tenuous atmosphere consisting mostly of nitrogen and methane, which is not conducive to supporting life as we know it.
3. Distance and Environment - Pluto's distance from the Sun and extreme cold temperatures make it inhospitable for sustaining life as we know it.
Therefore, even if Pluto was not cold, it lacks the essential conditions necessary for it to become the next Earth.

Source: Bernhard J. Stern, “The Challenge of Advancing Technology,” The ANNALS of the American Academy of Political and Social Science, 1945.
Even before the announcement of the unlocking of atomic energy, it could be said that advances in technology during the years of the war had been far greater than during many preceding decades. . . . With the development of prefabricated houses, transport and passenger planes and helicopters, quick-frozen, dehydrated, and other processed and packaged foods, improved gasoline, and new and improved types of power for industrial production, for transportation, for illumination, and for easing household burdens, cities can be freer to develop functionally in terms of the harmonious living of their populations. Advances in public health and in medicine have made possible precipitous declines in death and morbidity rates, so that healthy city populations can enjoy the leisure which shorter working hours make available to them. Illiteracy and ignorance, long anachronisms in industrial societies, can more easily be liquidated through advances in human psychology and in educational processes.

A man is carrying a Turkey Sandwich from Subway all while he is dodging the dog toys on the floor and being careful not to step on the two 75 pound dogs sleeping on the carpet. As he is making his way to his Lazy Boy, he accidently stubs his toe on the coffee table. Immediately, he begins to jump up and down on one foot to avoid stepping on the injured toe, throwing his sandwhich in the air, subseqiently scaring the dogs.
Explain the neural transmission of the pain signal using the following terms:
Sensory Neuron
Peripheral Nervous System
Interneuron
Motor Neuron
Action Potential
Neurotransmitter
Synapse
Answers
If a person stubs their toe, sensory neurons send information to the processing region of the brain via the Peripheral Nervous System - PNS. Sensory neurons transport information from the senses to the brain.
The Peripheral Nervous System (PNS) links sensory and motor neurons to the central nervous system (brain and spinal cord). After sensing an action potential, these sensory neurons follow this path to the processing center of the brain.
When the neuron gets enough excitatory signals to meet the threshold, a chemical/electrical signal is produced in the cell. This signal transmits information to nearby neurons via the synapses that connect them. This action potential will propagate until it reaches the brain.
The part of the brain responsible for information processing generates a signal by employing interneurons, which are neurons used to control communications between sensory and motor neurons and send this signal to motor neurons.
An action potential is generated in the motor neurons, which sends information instructing us to jump up and down in pain. Endorphines, our bodies' natural pain relievers, are released as a result of neurotransmitters being released in the brain as a result of receiving a signal from sensory neurons, allowing the perception of pain to diminish.
What is Neural Transmission?Neurotransmission is the mechanism by which signaling chemicals known as neurotransmitters are released from a neuron's axon terminal and bind to and interact with receptors on the dendrites of another neuron located a short distance away.
There would be no direct connection between cells if transmission did not exist—there would only be individual isolated cells. The nervous system's entire purpose is to manage and coordinate bodily function while also allowing the body to respond to and act on the environment.
