Apsychologist working from the biological perspective would study all of the following to see how they affect behavior and cognitive processes except a. attention b. brain cells c. genes d. the nervous system

Attention.

Explanation:

When a psychologist is working from the biological perspective then he should not consider attention as a factor because it is not a biological factor it is a psychological factor.

The factors like brain cells, genes and nervous system can be considered as the biological factors that can be used to determine the effect of brain cells, genes and nervous system on the cognitive process and behavior.

Hence, the correct answer is option A

The new Hazard Communication Standards provide teachers and students the right to manipulate chemical hazards.

Chemical hazards are non-biological substances that can cause damage to health. These are used in different enterprises, companies, school, universities and laboratories for different purposes such as cleaning, disinfection, scientific experiments, among others. When handling them, employees are exposed to them and are vulnerable to harm from these chemicals.  

There are many types of hazardous chemicals to be wary of, such as:

In the workplace, exposure to these substances represents a real occupational hazard and there must be regulations to ensure that they are safe to handle.

The Occupational Safety and Health Administration (OSHA) is the agency of the U.S. Department of Labor which determined the Hazard Communication Standards. This is a document with the necessary information to study the hazards of the chemical substances used by different employees in the companies, so that they are aware of the dangers of these substances. These employees have the right to know exactly what compounds they handle and the risks involved in their use as well as the precautions and care to be taken.

Therefore, by having these safety standards in place in schools and universities, teachers and students have the possibility and the right to handle chemical hazards safely to be able to conduct the class normally and learn what is necessary.
