The given question is incomplete, the complete question is:
Madison lives near the ocean. She’s formed a hypothesis that increased concentrations of salt in the air speeds the corrosion of certain metals. If Madison plans to test this hypothesis, she will have to deal with the following variables in her experiment: dependent variable: independent variable: one possible confounding variable:
Answer:
A variable, which is under study or observation in an experiment and changes concerning the independent variable is termed as a dependent variable. Based on the given experiment, Madison is checking the influence on the progression of corrosion of metals concerning the variations in the concentration of salt. This shows that the extent of corrosion of metals is a dependent variable.
A variable, which can be controlled or monitored like increased or decreased, and one is familiar with is termed as an independent variable. This variable is not affected by another variable, like a change in the concentration of salt is the air may exhibit an effect on the corrosion of the metal, however, the process that is, the corrosion of metals does not affect the concentration of salt in the air. Hence, the independent variable is the salt concentration in air.
A variable that possesses the tendency to change or influence both the independent and dependent variables is known as a confounding variable. If the airspeed is higher than it will carry the salt particles at a brisk rate and speed resulting in enhanced corrosion of metals. Likewise, if the speed of air is slower, there will be a reduction in the corrosion of metals. Hence, the confounding variable is the speed of air.
Answer:
Because they are the most destruction waves
Explanation:
Surface waves travel just below the earth’s surface. Examples of surface waves are Rayleighs and Long waves. Rayleighs cause ripples on the ground while long waves move the ground horizontally perpendicular to the direction of travel of the wave. Therefore, these waves are capable of destroying the foundations of structures and hence causing their collapse. Studying these waves allow these professionals to design foundations strong enough to withstand these waves.
Answer:
This is an example of Harrison's central nervous system working closely with his autonomic nervous system to give him energy and awareness to escape.
Explanation:
Harrison interprets the presence of the group of teenagers as an imminent danger and so he is on the run, which corresponds to a set of reactions that are triggered in the human body when a danger is around. At this point, the central nervous system and the subtonic nervous system are working together to get the adrenaline in Harrison's body to rise to a level that allows him to escape the group of teenagers. The central nervous system was then responsible for receiving and processing information that indicates to Harrison that he may be in danger. On the other hand, the autonomic nervous system is responsible for regulating the body's involuntary responses, being responsible for controlling various vital functions and at this time for the release of adrenaline in response to the dangerous situation.
<span>Scientists use the word gender/sex to refer exclusively to biological differences between men and women in anatomy, genetics, or physical functioning. Gender/sex is determined if the person is a female or male. It’s basically the word that most of the forms have in order to know the preference of the person filling up the forms or any other documents. </span>
