When you want to write, your brain must send and receive information from your hand. What type of nerve is most likely responsible for passing the information from the brain to the hand?
Peripheral neurons are of two types, sensory and motor. Sensory (afferent) neurons bring information about the world within and around the body from sense organs to the brain and spinal cord, while motor (efferent) neurons carry messages from the brain and spinal cord out to the muscles and glands.
The median nerve is most likely responsible for passing the information from the brain to the hand. As it furnishes motor functions to the wrist, hand, and forearm.
What is Nerve?A nerve may be defined as a glimmering white cord-like bundle of fibers in the body of an organism that usually transmits impulses of sensation to the brain or spinal cord, and impulses from the brain to the muscles and organs.
The median nerve provides the motor function to the specific organs of the body through motor neurons. Motor neurons typically transmit impulses of sensation from the brain and spinal cord to the muscles and specific organs.
This function of motor neurons is very vastly studied under the classification of the Peripheral nervous system.

P (purple) and p (white) are the dominant and recessive alleles for flower color in peas. Similarly, A (axial) and a (terminal) are the dominant and recessive alleles for flower position in peas. Two plants with the genotype PpAa are crossed. Which genotype is indicative of white axial flowers?
PpAa is indicative of white axial flowers.
PPAA is indicative of white axial flowers.
ppAa is indicative of white axial flowers.
Answer:
Option C, ppAa is indicative of white axial flowers.
Explanation:
It is given that Purple color (P) is dominant over white color (p). Thus in order to have a flower of white color , the flower must be homozygous recessive with an allele pair having two recessive alleles.
Similarly, Axial (A) is dominant over terminal (a) flower. Thus, a flower can be axial in two cases -
a) when both the alleles are same i.e AA
or
b) when one allele is A and the other one is a i.e Aa
Considering the above cases, all possible allele combination that will produce white axial flower are as follows -

A 70 kg person travels to planet where he weighs 1750 N. what is the value G on the planet
Final answer:
The gravitational acceleration (g) on the planet where a 70 kg person weighs 1750 N is calculated to be 25 m/s² by using Newton's second law (F = ma).
Explanation:
The question pertains to the calculation of gravitational force on a person with a known mass on a different planet and finding the acceleration due to gravity (g) on that planet. In this scenario, a 70 kg person weighs 1750 N on another planet. The formula to find the acceleration due to gravity is given by Newton's second law (F = ma), where F is the force (weight) and m is the mass, and a is the acceleration due to gravity.
To find the value of g on the planet, we rearrange the formula to solve for a (which represents g in this context): g = F/m. By substituting the given values, g = 1750 N / 70 kg, we can calculate the gravitational acceleration on the planet. The calculation is as follows:
g = 1750 N / 70 kg = 25 m/s²
Therefore, the value of gravitational acceleration (g) on the planet is 25 m/s².

What theme is featured in Machiavelli’s The Prince?
A. the value of living a morally conscientious life
B. the importance and limits of political power
C. the desire to achieve quick and cutthroat results
D. the need to win regardless of the consequences

B. the importance and limits of political power
Explanation:Niccolo Machiavelli was an eminent Italian author and statesman who in his best-known work, The Prince, described the means by which government may gain and maintain its power. He believed in gain of power by whatever means and to maintain it for long period of time. He said that gaining power is the only way to live with honor because the world is a place for the fittest people and not the weak ones. This famous theory is known as Realism in Political Science.
Answer:
B. The importance and limitis of political power
Explanation:
Machiavelli wrote The Prince in 1513, just after he was forced to leave Florence as a political exile. Dedicated to Lorenzo de’ Medici, the book is Machiavelli’s advice to the current ruler of Florence on how to stay in power. It was also his effort, though unsuccessful, to gain an advisory post in the Medici government. The Prince was not published until five years after Machiavelli’s death.
Machiavelli’s treatise makes a clear break from the Western tradition of political philosophy that preceded him. Beginning with Plato and Aristotle, the thinkers of this tradition were concerned with issues of justice and human happiness, and with the constitution of the ideal state. Until its final chapter, The Prince is a shockingly direct how-to manual for rulers who aim either to establish and retain control of a new state or to seize and control an existing one. Rather than basing his advice on ethical or philosophical principles, Machiavelli founds his political program on real-life examples. When explaining what a prince should or should not do in pursuit of his ambitions, Machiavelli cites the actions of well-known historical and contemporary leaders, both successful and unsuccessful. Throughout The Prince, Machiavelli explicitly aims to give an unsentimental analysis of actual human behavior and the uses of power. “I have thought it proper,” Machiavelli writes of a prince’s conduct toward his subjects, “to represent things as they are in a real truth, rather than as they are imagined” (p. 49).
Which of the following is not a way that energy producing technologies can impact aquatic viability? a. waste products entering waterways b. disruption of water flow c. increased sedimentation d. filtration of pollutants
Answer: Filtration of pollutants
Explanation: The filtration of pollutants is not a way by which the energy producing technologies will affect the aquatic viability.
This is because removing the pollutants from water will improve the overall quality of water and it will not affect the viability of water. The flowing water or still water is highly polluted and it affects the aquatic life adversely.
To conquer these problem filtration of pollutants is necessary and this technique removes all the pollutants from water and makes the water clean without affecting its viability.
