Nancy measured the volume of the liquid in her experiment five times (95.0 mL, 95.5 mL, 90.5 mL, 97.0 mL, 96.5 mL). The exact measurement is 96.1 mL. What can be concluded about the precision and accuracy of her measurements?

Answers

Answer 1
It can be concluded that there is very little precision and accuracy as she was over 5mL off at one point.

Answer 2

Answer:

The measurement is not at all accurate and precise

Explanation:

Precision of any measurement is its nearness to the actual value. Here, all the measurements [tex]95.0, 95.5, 90.5, 97.0, 96.5[/tex] have a significant difference in reference to the exact value i.e [tex]96.1\\[/tex]. Thus, all these measurements are not precise.

The accuracy of any measurement is its exactness to the actual value. Here, none of the values lie near to the exact measurement i.e [tex]96.1\\[/tex]. Thus, all the measurements are not accurate even.

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?

Answers

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.

Therefore, it is well described above.

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

Answers

d. filtration of pollutants

Hope this helps : )

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.

Final answer:

The primary curves of the vertebral column are the thoracic curve and the sacrococcygeal curve. These curves increase the vertebral column's strength, flexibility, and ability to absorb shock.

Explanation:

The primary curves of the vertebral column are the thoracic curve and the sacrococcygeal curve. These curves are called primary curves because they are retained from the original fetal curvature of the vertebral column. The thoracic curve involves the thoracic vertebrae, while the sacrococcygeal curve is formed by the sacrum and coccyx. These curves increase the vertebral column's strength, flexibility, and ability to absorb shock.

A mineral with a hardness of 6 will scratch a mineral with a hardness of more than 6. true or false

Answers

Answer: False

Explanation: Well according to the hardness scale the answer would be self explanatory. An example of something at the hardness of 6 is the mineral feldspar which is a pretty solid item, but if you were for example, try to scratch a diamond (a gemstone with a hardness over 6) you would not have any luck scratching anything off that diamond.

The hardness of the water increases as the scale grows from 1 to 10. Therefore, the statement is false.

What is meant by hardness?

The scale at which the hardness is measured is known as the Mohs scale. This scale is used to measure the concentration of the mineral in the water. The range of the scale is from 1 to 10.

The softest water will get a score of 1 whereas the hardest will be 10. For example, talc power is the softest having a score of 1 whereas diamond is the hardest material having a score of 10.

Identification of the hardness of the material is important to find out. The score of the hardness will help in understanding the properties of the material. The properties of water resistance are permanent distortion, penetration, and scratching.

PpAa is indicative of white axial flowers.



PPAA is indicative of white axial flowers.



ppAa is indicative of white axial flowers.

Answers

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

Answers

Weight = mass X gravity.  Gravity = weight divided by mass. That's 1750 N / 70kg = 25 m / sec-squared.

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 are the three common patterns of population distribution?

Answers

Clumped, evenly spaced, and random 
There are three common patterns of population distribution. These are clumped, uniform or evenly spaced and random. Clumped distribution is the most common type found in nature. The distance between neighboring individual is at a minimum. This is common among organisms that are usually preyed such as in herds or family groups. Evenly spaced distribution maximizes the distances between individuals. There is usually competition for a resource. Penguins are an example of this distribution. Random distribution or unpredictable spacing is the least common among the three. Each individual is independent of the other. They occur in environments that have consistent environmental resources and conditions. 

The three (3) common patterns of population distribution include the following:

I. Clumped.

II. Uniform (evenly spaced)

III. Random.

A population can be defined as the total number of living organisms such as animals, plants and human beings that are living together in a specific geographical region (location), at a particular period of time.

Population distribution can be defined as a pattern that describes where people are living in a specific geographical region (location), at a particular period of time.

Hence, population distribution shows the pattern of how people are spread across specific geographical region (location), at a particular period of time.

Generally, the three (3) common patterns of population distribution are:

Clumped: the population is tightly packed and not well spaced.Uniform (evenly spaced): the population is spread out uniformly.Random: the population doesn't follow a specific pattern.

D. the need to win regardless of the consequences
NextReset

Answers

Answer:

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).

1. Which of the following do chordates NOT have at any point in their lives? notochord pharyngeal gill pouches nerve cord none of the above

Answers

Gill pouches seems like the most reasonable answer, only because a chordate needs a notochord and a nerve cord.

Answer:

The correct answer would be none of the above.

Explanation:

Chordata has 5 major characteristics that they have at some stage in their lives, a dorsal tubular nerve cord, a notochord, pharyngeal gill slits, a post- tail, and a thyroid/endostyle gland.

The notochord is a flexible, rod-like structure that is present in the development stage of all chordates and reason for the name of the phylum. Nerve cord is rise from the ectoderm and develops into a hollow tube. pharyngeal gill slits let water enter and exit the mouth during feeding.

Thus, the correct answer would be none of the above.
