Double-blind design: this is how the study will be conducted. This means that in this study, participants will know which treatments are being applied to each participant. In this case, the researcher can hire a doctor or health professional who can deliver the different treatments to the participants without the researcher and the participants themselves knowing what treatment is being delivered and which participants are not receiving any treatment.

Antagonist: It will be a substance used to establish connections in the participants' neurological receptors, but without activating these receptors and preventing any other substance from activating them.

Acetylcholine: Will be the neurotransmitter tested in treatments, as it is the main neurotransmitter often related to the symptoms of Parkinson's disease, alzheimer's disease, multiple sclerosis and schizophrenia

Positron Emission Tomography (PET): It will allow the visualization of images that will allow the evaluation of the functioning of the neurotransmitters related to each tested treatment.

Blood-brain barrier: It will allow the assessment of the metabolic function of the participants' brain, as it protects the nervous system from toxic and harmful substances. This cerebral metabolic function will be evaluated in relation to each treatment applied.

Myelin sheath: is the protective layer of nerve cells. It is usually damaged in people who have Parkinson's disease, alzheimer's disease, multiple sclerosis and schizophrenia, for this reason, it will allow the assessment of their protection in relation to each treatment tested.

Steps in a Criminal Case

A Crime Is Allegedly Committed

Police are notified and investigate an alleged crime by interviewing victims, witnesses, suspects, gathering physical evidence, taking photographs, measuring the crime scene, and taking fingerprint and DNA samples if available.


A Person Is Arrested

Police may arrest a suspect on the spot or if the officer has probable cause to believe a misdemeanor or felony was committed. The police may refer the case to the District Attorney’s Office suggesting potential charges.


The District Attorney’s Office Reviews The Case

A prosecuting attorney will determine whether a person should be charged with a crime by thoroughly reviewing all reports and records, witness statements, and the suspect’s prior criminal or traffic record. The criminal case is either charged or declined.


Criminal Charges Are Issued Or Declined

If a case is charged, the prosecutor issues a criminal complaint charging the suspect with committing a misdemeanor, felony, or both. Persons charged with a misdemeanor may be able to post bail and be released from jail. Persons charged with a felony crime must wait for their initial appearance in Arraignment Court.


Initial Appearance

This is the first court hearing after someone has been arrested and charged with a crime. The judge or court commissioner informs the defendant what the charge(s) are, maximum penalty if convicted, and their rights to an attorney. If the defendant is still in jail, bail and any other conditions are set. Often a “No Contact Order” will be imposed, which prohibits the defendant from having any contact with a person who is a victim or a witness in the case.


Entering A Plea

In misdemeanor cases, the defendant is asked to enter a plea of guilty, not guilty or no contest. In felony cases, a date is set for a preliminary hearing.


Status Conference

A court hearing to determine the status, or progress and direction, of a case.


Preliminary Hearing

This is an evidentiary hearing in which the District Attorney’s office must prove to a judge or court commissioner that there is enough evidence to believe the defendant committed a felony.


Arraignment

A criminal defendant's first appearance on the formal charges before a judge. The defendant is formally charged and enters a plea of guilty, not guilty, or no contest. This occurs at the initial appearance in misdemeanor cases and at some point following bind over at preliminary hearings in felony cases.


Pretrial Conference / Court Settlement Conference

A court hearing to resolve issues in advance of a trial; courts sometimes will accept entry of pleas of guilty or no contest at these hearings.


Plea Hearing

A hearing at which the defendant's responds to a criminal charge by entering a plea of guilty, not guilty or no contest. A plea agreement or plea bargain is an agreement between the prosecutor and the defendant for the defendant to plead guilty or no contest under certain terms and conditions, which must be approved by the judge, to prevent going to trial.


Trial

A hearing at which evidence is presented to a judge or jury to determine whether the defendant is guilty beyond a reasonable doubt. A defendant may be found guilty of all, some, or none of the criminal charges.


Sentencing

A court’s decision as to the penalties appropriate for crimes established by convictions.


Appeal

A defendant may appeal their case after sentencing.


Post-Conviction Motion Hearing

A defendant may be revoked for not following the terms of his probation. Post-Conviction Motions may be filed to deal with any post-conviction issues.

hey guys I have a hard question for my college pre help I have done this question but I want to see if you can get it
myrzilka [38]

Replacing <em>F</em> with <em>F</em> + 1 gives

5/9 (<em>F</em> + 1 - 32) = 5/9 (<em>F</em> - 32) + 5/9 = <em>C</em> + 5/9

so a temperature increase of 1º F translates to a 5/9º increase in Celsius, so I is true.

Replacing <em>F</em> with <em>F</em> + 5/9 gives

5/9 (<em>F</em> + 5/9 - 32) = 5/9 (<em>F</em> - 32) + (5/9)² = <em>C</em> + 25/81

so increasing the temperature by 5/9º F amounts to a 25/81º increase in Celsius, so III is false.

Solve for <em>F</em> in terms of <em>C</em> :

<em>F</em> = 9/5 <em>C</em> + 32

Replacing <em>C</em> with <em>C</em> + 1 gives

9/5 (<em>C</em> + 1) + 32 = 9/5 <em>C</em> + 32 + 9/5 = <em>F</em> + 9/5

and 9/5 = 1.8, so a 1º C increase translates to a 1.8º F increase, so II is also true and the answer is D.
