For example, one cell type may not be damaged by a toxic particle whereas a different cell type may be damaged or even killed following exposure. This response is due to the different responsibilities of different cells. Some cell types are capable of controlling for toxicity, while others are not designed to handle toxicity and typically rely on other cells to protect them. This has resulted in inaccurate measurements of nanoparticle toxicity when compared to toxic exposures in animals or humans. This is due to the complex cellular system in living creatures compared to the simplistic monoculture model.
The possibility of decoding an actual difference between recovered memories and false memories, through biological techniques. Because false memories can be created, examining these creations in a laboratory setting can shed light on facts overlooked. Exploring these issues will also help with the development of better therapeutic techniques for therapists in dealing with memories. This can lead to an easier process for patients and therapists if they must go through the legal system in relation to an uncovered memory. Recovered Memories versus False Memories: Is it possible to determine what is real?

Each laboratory has its own standard and guidelines rather than having uniformity across the industry. This allows one forensic labs results to be different to another’s based on their own individual practices. The standards and guidelines for the checking of forensic laboratories varies from state to state and the inspection is peer assessed. This is a problem as the auditing of the labs may be subject to bias rather than using an independent authority. Lab test guidelines might not result in all evidence having to be reported.
Maybe the students spend too much time on “school science” and do not make the connection between what is learned in science class and the world around them. The teacher’s job is not only to make the science material manageable for the students to learn, but it is also to show the students how science applies to everyone and everything. Using the problem-based learning approach is a great way for a teacher to combine these two sciences (Uyeda et al. 24). It is the key that a teacher uses to open the door to the minds of students who need to know how what they are learning applies to the real world.

According to Maltby (2013), biometrics may be used in some situations because passwords and magnetics-strip IDs can be lost or stolen but biometrics may reveal a person sensitive medical information and linking records of biometric systems could create a record of person location like GPS system, (Maltby, 2013). Access to a workstation inside of an employment can be password-based because some people may continue to feel uncomfortable with using biometrics and most workstations do not need the added security or expenses in order to afford biometrics on the workstation. If a computer houses highly sensitive information then biometrics may be used along with password-based access. Biometrics is built-in with some laptops such as finger or thumb print used to log into the laptop. Companies may purchase laptops in bulk to replace a lot of older machines.
In the experiment, scientists used an MRI scanner to photograph people’s mental process when performing several tasks simultaneously. The result shows that the brain has to switch among tasks, which means the brain will set the previous task aside before processing the new task. The times for switching are not obvious if the tasks are simple, but according to Weissman, even simple tasks can overwhelm the brain when they are processed together (Jon Hamilton, 2008). In her research paper “Is Multitasking Limited by a Mental Bottleneck?” Frederik Joelving reveals that the brain area which limits multitasking is the prefrontal cortex. The prefrontal cortex is the core executive of our brain, this brain region responsible for planning complex cognitive behavior, and decision-making.
Many other jobs drug test their employees. It should be like any other job. In this essay, what was discussed was why students shouldn’t be drug tested. There are many good and bad sides to drug testing students. The pros are that it might help students get away from drugs, and it may help someone see the consequences to drugs.
