HiSET Science Practice Test #3
Which one of the following waves is an example of a type of wave known as an electromagnetic wave?
On the electromagnetic spectrum, gamma waves have the shortest wavelengths of any other type.
What happens when an element moves from one physical state to another?
An element's chemical state does not change when it changes from one physical state to another. Liquids, for instance, can freeze. However, their chemical makeup remains unchanged.
Which of the following statements best illustrates the Mayflower Compact's impact on colonial America?
After a debate over where they should build a colony in the Americas, the Mayflower's male passengers signed the Compact. The Compact became the written foundation for their last colony's rules. The Mayflower Compact is not best understood as a prototype for the Bill of Rights because it does not enumerate specific rights. Though the Compact served as a foundation for government in part, it did not declare independence from King James; the Compact's last phrase, for example, refers to King James as the writers' ruler. Finally, while there is religious terminology in the Mayflower Compact, it is a brief document that does not describe, defend, or establish as official any particular religious theory, including Puritan religious philosophy.
Which process is responsible for the direct transfer of thermal energy from particle to particle throughout matter?
The process of transferring thermal energy from one substance to another in physical contact is known as conduction. For this process to occur, the particles of both substances must collide with one another.
The National Centers for Environmental Information provided the information presented in this table. It shows the average temperature in the United States at intervals of five years, beginning in 1920 and continuing through 2015.
A change that is considered significant over five years must be at least 0.2 degrees Fahrenheit. A change of at least 1.0 degrees Fahrenheit over five years is considered extreme.
According to these statistics, which two years were the most comparable?
The temperature difference between these two years is the smallest at 0.01 degrees.
Which of the following states of matter has the fewest total molecules of kinetic energy?
Because solids are made up of closely packed atoms or molecules that are locked in position and exhibit very little movement, they contain the least amount of kinetic energy compared to other types of matter. Plasmas and gases have the highest levels of power of all the states.
Which law best describes the way in which two charged particles interact via the electric force?
Coulomb's law characterizes the electric force that exists between two charged particles. According to this theory, charges of the same polarity repel one another. In contrast, leaders of opposite polarity attract one another, and the further apart the costs are, the less force they will exert on one another.
As part of a larger investigation into the relationship between skin type and degree of redness when subjected to varying intensities of UV light, a researcher devised an experiment to determine the extent to which various types of skin turned red when subjected to the aforementioned conditions. The researcher began by classifying one hundred people into six distinct categories based on their skin type. Next, he subjected these individuals to progressively higher doses of UV light and monitored the degree to which their skin became reddened.
In this experiment, which variable is considered to be an independent variable and which is considered to be a dependent variable?
Scientists make use of both independent and dependent variables when experimenting. In a scientific investigation, the scientists will make adjustments to one variable, known as an independent variable, to observe the effects of those adjustments on another, known as a dependent variable. The variable that is being measured is referred to as a dependent variable. In this experiment, the scientist controls two factors that are considered independent variables: the type of skin and the amount of UV light. The degree of skin redness will serve as the dependent variable in this study.
To prepare soup, Jonah first brings a pot of water to a boil, then adds various spices to the water, and stirs the mixture until the spices are completely dissolved. After that, she adds a few different vegetables that have been chopped. What component of her mixture is the solute?
A substance that can be dissolved in another substance is referred to as a solute. The spices are the solute in this particular case.
Martin Luther King, Jr. and Malcolm X were both pivotal figures in the civil rights movement in the United States. Which of the following statements best represents the difference in their civil rights approaches?
While Martin Luther King was known for his nonviolent activism, Malcolm X championed self-defense against white assault. King organized ordinary folks during his work; however, Malcolm X focused on black neighborhoods rather than working with local white political leaders. Malcolm X was also known for speaking out against black Christians, claiming that their practice was linked to tyranny. Finally, the claim that "Martin Luther King, Jr. tied Christianity to civil rights..." is debatable because King did not promote Black Nationalism, although Malcolm X did.
Charrie possesses the disease's dominant gene. Which of the following claims about Charrie is FALSE?
If Susan carries the dominant gene for a disease, she most likely has the disease. Her children would have a 50% chance of inheriting the disease as well. Her parents’ number of chromosomes is irrelevant, but not false.
Which of the following statements best explains the characteristic Ll, given that "L" denotes a person's height and "l" denotes their stature?
This quality Ll describes a person's phenotype or the characteristics associated with the genes they carry. It is referred to as heterozygous because it takes both a dominant gene and a recessive gene. Because the L gene, which is responsible for tallness, is the dominant allele, the person's height is the phenotype, or the outward manifestation, of the genes they carry.
The National Centers for Environmental Information provided the information presented in this table. It shows the average temperature in the United States at intervals of five years, beginning in 1920 and continuing through 2015.
A change that is considered significant over five years must be at least 0.2 degrees Fahrenheit. A change of at least 1.0 degrees Fahrenheit over five years is considered extreme.
Which of the following statements best describes the patterns that have been observed in the data that have been presented?
Although it is factually accurate to respond that temperatures simply rise over time, the response acknowledging that temperatures fluctuate over a century is more accurate and, as a result, is the answer that should be chosen.
What is the name of the unit that scientists use to measure force?
The name of the unit that scientists use to measure force is a newton.Forces or newtons can be added up if they are acting together. They can be subtracted if they are acting in opposition.
Which theory contends that light is made up of tiny bundles of energetic particles?
According to the quantum theory, light is made up of very tiny bundles of energetic particles. Photons are the name of the constituents. We learn how much energy there is from the photons.
What took the place of the food pyramid, which represented the kinds of food people should eat, in June 2011?
The food plate was introduced in June 2011 to replace the food pyramid. The pyramid baffled a lot of people. The new plate displays the serving sizes of cereals, proteins, fruits, and vegetables together with a side of dairy.
