why do environmental and occupational health (eoh) practitioners need a firm grasp of basic epidemiological principles in their daily work?
Answers
Environmental and occupational health (EOH) practitioners need a firm grasp of basic epidemiological principles in their daily work as epidemiological principles help EOH practitioners to recognize and analyze disease patterns and patterns of exposure to environmental contaminants that cause disease.
Epidemiology is the study of how diseases spread and how to prevent or treat them. EOH practitioners must know the science behind disease transmission and prevention, as well as how to perform public health surveillance and risk assessments.
EOH practitioners work in a wide range of settings, including hospitals, local health departments, state and federal government agencies, and academia. They often work with colleagues from various disciplines such as toxicology, biostatistics, and environmental science, among others. They use a range of epidemiological tools to investigate environmental and occupational health hazards that can affect human health. They must also understand the statistical methods used to analyze and interpret data obtained from epidemiological studies.

Plants take in carbon dioxide and release gas
Answers
Answer:
yes, but by gas you mean oxygen right?
Explanation:
Answer: During photosynthesis, plants take in carbon dioxide (CO2) and water (H2O) from the air and soil. ... This transforms the water into oxygen and the carbon dioxide into glucose. The plant then releases the oxygen back into the air, and stores energy within the glucose molecules.

what is the role of water in light reactions of photosynthesis? multiple choice provides energy to run electron transport chain hydrolyzes napdh back to nadp water accepts electrons incorrect water donates electrons
Answers
Water plays a crucial role in the light reactions of photosynthesis. The role of water is to donate electrons to the electron transport chain in the light-dependent reactions.
When light energy is absorbed by the chlorophyll pigments, water molecules are split by the process of photolysis, and the electrons and protons from the water molecule are used to create ATP and NADPH, which are important energy carriers. The process of water splitting also releases oxygen gas into the atmosphere, which is an essential byproduct of photosynthesis. Therefore, the role of water is not only limited to providing electrons to the electron transport chain but also involves oxygen production and energy generation.
Overall, the importance of water in photosynthesis cannot be overstated. It is a crucial reactant in the light-dependent reactions and plays a vital role in energy production and oxygen generation. The photolysis of water and the subsequent electron transfer are essential for the process of photosynthesis to take place, and without water, the process of photosynthesis cannot occur.

During a boxing match, Sammy was hit on the side of the neck. He stopped breathing temporarily due to damage to the:
a. brachial plexus
b. cervical plexus.
c. sacral plexus.
d. lumbar plexus
Answers
Sammy stopped breathing temporarily due to damage to the cervical plexus.
The cervical plexus is a network of nerves located in the neck region. It consists of nerve fibers that originate from the spinal nerves C1 to C4. The cervical plexus innervates various structures in the neck, including the muscles and skin.
When Sammy was hit on the side of the neck, the impact likely caused damage to the cervical plexus, resulting in a temporary cessation of breathing. The cervical plexus provides innervation to the muscles involved in respiration, such as the diaphragm and the muscles of the neck and chest.
Damage to the cervical plexus can disrupt the normal functioning of these respiratory muscles, leading to breathing difficulties or even temporary cessation of breathing. In such cases, immediate medical attention is crucial to ensure proper airflow and resumption of breathing.
Therefore, in this scenario, the temporary cessation of breathing experienced by Sammy is likely due to damage to the cervical plexus, which plays a vital role in controlling the respiratory muscles in the neck and chest.

The inner membrane of the mitochondria provides a large for breaking the bonds in sugar molecules.
Answers
Answer:
Explanation:
It maintains the proton gradient that drives oxidative phosphorylation.
The inner membrane of the mitochondria does provide a large surface area for breaking down the bonds in sugar molecules.
What is mitochondria?Mitochondria are organelles found in the cells of eukaryotic organisms, including animals, plants, and fungi. They are often referred to as the "powerhouses" of the cell because they are responsible for producing the majority of the cell's energy supply. Mitochondria have a double membrane structure, with an outer membrane and an inner membrane. The inner membrane is folded into small, finger-like projections called cristae, which increases the surface area of the membrane.
Mitochondria are the site of cellular respiration, a process by which energy is extracted from organic molecules, such as glucose, to produce the energy-rich molecule adenosine triphosphate (ATP). The energy released from this process is used by the cell to perform various functions, such as muscle contraction and protein synthesis.
Mitochondria also have their own DNA and reproduce independently of the cell. They are thought to have originated as a symbiotic relationship between ancient cells and bacteria. They have their own genetic material, which suggests that they have a separate evolutionary history from the rest of the cell.

4. The Na'vi people have a complex relationship with the ecosystem of Pandora. They understand that everything is interconnected and that they must live in harmony with the environment to survive. Jake's possible interactions with the Na'vi clan will involve him learning their ways and respecting their culture.
6. The network of energy that flows through the forest of Pandora is a complex system where everything gives energy to the other. The plants absorb the sun's energy and convert it into food, which is then consumed by the animals. The animals, in turn, produce waste that fertilizes the plants, and the cycle continues.
7. The destruction of the trees and land on Pandora is similar to deforestation today. Destroying one part of the ecosystem affects the other parts by disrupting the balance of the ecosystem. The loss of trees can lead to soil erosion, loss of biodiversity, and changes in weather patterns.
8. The Na'vi people won't leave and migrate to another tree because they have a spiritual connection to their home tree. They believe that their ancestors reside in the tree, and that it is their duty to protect it.
9. From an ecologist's point of view, Avatar highlights the importance of living in harmony with the environment. The movie shows the devastating effects of human greed and the destruction of the environment. It also highlights the importance of biodiversity and the interconnectedness of all living things.

explain how the relationship between light and pigment production might serve as a protective mechanism
Answers
The relationship between light and pigment production can serve as a protective mechanism for plants and other organisms. Pigments absorb light energy and convert it into chemical energy, which is then used to drive metabolic processes such as photosynthesis.
This allows plants to absorb light and use it to create energy. Pigment production can also help protect organisms from dangerous ultraviolet radiation. Pigments absorb ultraviolet light and prevent it from reaching the cells beneath. This can help protect them from damage caused by exposure to UV radiation.
In addition, the pigments can act as natural sunscreen, reducing the amount of harmful radiation that reaches the organism’s skin. Pigments can also provide camouflage and protection from predators. By changing the colour of their skin, organisms can blend into their environment, making them less visible to predators. Overall, the relationship between light and pigment production can provide an effective form of protection for plants and other organisms.
