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, <u>employees are exposed to them and are vulnerable to harm from these chemicals</u>.
There are many types of hazardous chemicals to be wary of, such as:
- Carcinogens
- Neurotoxins
- Acids
- Systemic toxins
- Asmogens
- Silica dust
- Lead
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. <u>This is a document with the necessary information to study the hazards of the chemical substances used by different employees in the companies</u>, 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.

Answer: Heterotroph
Explanation: Good luck! :D
The DNA molecule is packaged into thread-like structures called chromosomes. Each chromosome is made up of DNA tightly coiled many times around proteins called histones
Answer:
c
Explanation:
Most DNA is located in the cell nucleus (where it is called nuclear DNA)
<h2>Evolution of phylogenies </h2>
Explanation:
- The genome of the endosymbiont is all the more firmly identified with individuals from the gathering in which it initially developed, while the nuclear genome of the inundating living being has its own evolutionary trajectory.
- The accumulation of various inheritable attributes after some time which prompted the arrangement of another species
- Nuclear and organellar genes advanced at various rates, clouding developmental connections.
- Some mitochondrial genomes have been decreased definitely in size, losing a large number of the protein genes encoded in creature mtDNA just as a few or all mtDNA-encoded tRNA genes.
- At ∼6 kb in size, the mitochondrial genome of Plasmodium falciparum (human intestinal sickness parasite) and related apicomplexans is the littlest known, harboring just three protein genes, profoundly divided and improved little subunit (SSU) and enormous subunit (LSU) rRNA genes, and no tRNA genes.
- In stamped differentiate, inside land plants, mtDNA has extended generously in size (>200 kb) if not in coding limit, with the biggest known mitochondrial genome right now.
