the hazard communication standard is also known as
Answer:
OSHA's Hazard Communication standard, also known as the “Right to Know Law,” is designed to ensure that vital information about chemical hazards and protective measures is passed along to workers who may come in contact with or handle these types of chemicals.
Explanation:
The Hazard Communication Standard (HCS) is also known as the "Right-to-Know" standard because the standard gives workers the right to know about hazardous chemicals.
What is the Hazard Communication Standard?The HCS was created by the Occupational Safety and Health Administration for workers so that they are informed about the hazards of the chemicals they work with and to reduce the incidence of injuries, and the standard requires chemical manufacturers, importers, and employers to communicate information about hazardous chemicals to workers through a variety of means. Employers must inform workers about the identity and hazards of any chemicals they work with, and HCS applies to all hazardous chemicals used in the workplace, including chemicals used in manufacturing and construction.
Hence, the Hazard Communication Standard (HCS) is also known as the "right-to-know" standard.

what is the main function of the reticular activating system?
The reticular activating system's main function is regulating transition between arousal and sleep−wakeness.
what is reticular activating system?The reticular activating system (RAS) is a bundle of nerves located in the brain and it is responsible for regulating wakefulness and sleep-wake transitions.
It is also involve in filtration of noise with processing of messages or make it slower during sleep, it alters the brain's electrical activity, electrical voltage of brain waves and the speed.
The primary function of RAS is higher at brain centres when important messages are received and filter the important messages, for example The eye sends messages to the brain through the optic nerve.
If the RAS system is damaged, it can cause sleep problems, lethargy, or coma, also play a role in narcolepsy and degenerative brain disorders like Parkinson's disease and supranuclear palsy

Antigen-presenting cells usually display processed antigens to T cells in the LYMPH NODES. These nodes are regions of the body where lymphocytes are activated.
T cells are white blood cells (lymphocytes), which form part of the immune system.
These cells (T cells) develop in the bone marrow.
The lymph nodes are secondary lymphoid organs in which naive T cells that search for specific antigens examine antigen-presenting cells (APCs) for their activation.

Suggest why the blood flows through many channels in the dialysis unit, rather than through a single large channel
Hello there I hope you are having a great day :)
Blood travels through many different channels to optimize absorption. The water potential in the solution in the dialysis machine will need to be less than in the blood. If all the blood flows through a single large channel the blood water potential may be more negative than outside, therefore slowing absorption.

what is the ultimate source of electrons for photosynthesis in plants?
Answer: Water
Explanation:
What is the ultimate source of electrons for photosynthesis?
In photosynthesis, water is the source of electrons and their final destination is NADP+ to make NADPH
Photosynthesis is a plant process to make food and energy. It includes various steps to release energy. The water molecule is the ultimate electron donor in the process.
What is photosynthesis?Photosynthesis is said to be the process that converts solar energy into the chemicals that are used as the energy source in cellular respiration activities. Here, sunlight, carbon dioxide, and water act as reactants.
The carbon dioxide and water undergo splitting by the membrane pigments and then the electron produced from water is carried with enzymes to make NADP⁺. This is further used to make NADPH. As result oxygen along with the sugar molecules are produced and are rich in ATP.
Therefore, water is the foremost source of electrons for photosynthesis in plants.

where do the light-independent reactions take place in cam photosynthesis?
Answer:
Explanation: In plants, carbon dioxide (CO2) enters the leaves through stomata, where it diffuses over short distances through intercellular spaces until it reaches the mesophyll cells. Once in the mesophyll cells, CO2 diffuses into the stroma of the chloroplast, the site of light-independent reactions of photosynthesis.
The place from where the light-independent reactions occur in cam photosynthesis would be:
Chloroplast stroma
PhotosynthesisThe chloroplast stroma is where CAM photosynthesis takes place. It starts when the plant's stomata open at night, allowing CO2 gas to flow into the cytoplasm of CAM mesophyll cells.
Carbon dioxide is exclusively collected in CAM plants at night, when the stomata open.
Malic acid is turned back to carbon dioxide during the day.
When the sun shines, light reactions produce energy for the Calvin cycle, which allows carbon dioxide to be transformed into sugars.

Scientists have observed a gradual increase in temperatures in locations all across Earth, an event often called . The increase in temperature is one aspect of , a long-term change in weather patterns.
Answer:
Climate or Global Warming
Dunno what you're asking exactly-
A long-term change in the typical weather patterns that have come to characterize local, regional, and global climates on Earth is referred to as climate change.The phrase is synonymous with a wide variety of observed outcomes that are a result of these changes
What is a long-term change in weather patterns?
Storms, heat waves, floods, and droughts are just a few of the disasters that are getting worse as a result of rising temperatures.Warmer temperatures produce an atmosphere that can hold onto, release, and gather more water. This alters weather patterns such that wet areas get wetter and dry ones get drier. The long-term pattern of the weather in a place is called the climate.Hour by hour, day by day, month by month, or even year by year, the weather might change.A region's climate is determined by its weather patterns, which are typically monitored for at least 30 years.The climates in different places of the world vary.When the weather is consistent for several days or weeks at a time, a weather pattern develops.Cold weather, wet and rainy weather, and hot and dry weather are a few typical weather patterns.Heat waves, flooding, and blizzards can occur as a result of persistent weather patterns. Climate Change Causes... Greenhouse Gases.... Reflectivity or Absorption of the Sun's Energy.... Changes in the Earth's Orbit and Rotation.... Variations in Solar Activity.... Changes in the Earth's Reflectivity.... Volcanic Activity. These phenomena cover changes like sea-level rise, ice mass loss in Greenland, Antarctica, the Arctic, and mountain glaciers around the world, changes in flower/plant blossoming, and extreme weather events, in addition to the higher temperature trends indicated by global warming. The average thickness of 30 well-studied glaciers has declined by more than 60 feet since 1980, indicating that glaciers are thinning. Due to climate changes, the ocean level is rising, glaciers are melting, CO2 levels in the atmosphere are rising, the forest and wildlife are disappearing, and water life is also being disrupted.In addition, it is predicted that many species of plants and animals would become extinct if this trend continues.To learn more about weather patterns refer
