Answer:
Any scientific investigation in its simplest form involves collecting information, while a controlled experiment is a tightly controlled investigation that tests a hypothesis.
Explanation:
All the scientific investigations start with a particular question. The question decides what type of investigation should research take. A controlled experiment is an investigation which allows a particular variable to change and all other variable controlled to remain constant to see the effect on dependent variable to test a particular hypothesis while other types of investigations are used to increase the knowledge or information about the particular research subject.
Answer:
Tuning the keys.
Explanation:
<em>"Guitar strings are tuned (tightened and loosened) using their tuning keys. </em><em>Applying too much tension to a string tightly can raise it to the pitch of the next note, while loosening it can easily lower it the same amount.</em><em> Increasing the tension raises the pitch. The length of a string is also important."</em>

Answer: This is an example of downregulation and upregulation.
Explanation:
Downregulation is a process in which cells decrease the production of one of their components, responding to an external stimulus. Upregulation, on the other hand, is when cells increase the production of one of their components in response to an external stimulus.
In this case, the decrease in insulin receptors would make the cell less sensitive to the hormone.
If there's a lot of insulin around those cells, the cell would have to decrease its sensitivity, otherwise, it would metabolise more glucose than the body needs. The contrary would happen if there was too little insulin around those cells, they would have to become more sensitive to it by increasing the number of receptors.
Answer:
19,551 J!
Explanation:
The formula is PE = ham (h=height, a= acceleration or 9.8, m= mass)
PE = (95)(9.8)(21)
PE = 19,551 Joules
