Does hermatite occur naturally
Answer:
I would say yes.
Explanation:
Hematite is found as a primary mineral and as an alteration product in igneous, metamorphic, and sedimentary rocks. It can also form during contact metamorphism when hot magmas react with adjacent rocks. The most important hematite deposits formed in sedimentary environments.
I hope I'm correct
Answer:
Hematite is found as a primary mineral. it is naturally formed in sedimentary environments.
Gypsum is a naturally occurring stone, a metallic salt of calcium. It commonly forms as an evaporite from the dissolution of limestone by exposure to sulphuric acid from volcanic activity
So the answer is YES
How to use bacteria as a treatment for sewage waste
Answer: hope this helps
Explanation:
Aerobic bacteria use oxygen, which is added mechanically, to break down wastewater contaminants, converting it into energy. Bacteria use this energy to grow and reproduce. Anaerobic bacteria obtain oxygen from their food source. As anaerobic bacteria break down sludge, they produce methane gas. This methane gas can be used as an alternative energy source, called biogas, to fuel the wastewater treatment process.
Explanation:
Biological wastewater treatment is the most common method of sanitation in the world. This technology uses different types of bacteria and other micro-organisms for the treatment and cleaning of polluted water.
Wastewater treatment is as essential to human health as it is to environmental protection. Indeed, the use of these bacteria accelerates the treatment of pollution on a small surface: the purification plant. It’s better than letting the river handle it, because even though it’s the same purification process that occurs in nature, the quantities of pollution discharged today are too high to keep the natural cycle intact.
Thus, sewage treatment plants can prevent eutrophication of rivers, for example, but also prevent the diffusion of diseases.
Municipal and industrial effluent is the main source of wastewater. And thanks to the use of micro-organisms, we are able to degrade the content of these organic wastes as they are used as a source of food and energy to grow and multiply.

to allow movement of the tendons within the carpal tunnel zone, each tendon is encased in a __________.
To allow movement of the tendons within the carpal tunnel zone, each tendon is encased in a sheath.
The sheath is a fibrous but at the same time serous element that is composed of a viscous liquid called the synovium, which is designed in order to allow the tendons to move with the bones.
The function of the sheaths is to allow a correct sliding between the tendon where it meets the bone through which it passes.
The importance of sheaths for the biomechanics of movements is that if they were not located in the tendons, these tissues would wear out very easily, thus causing injuries such as tenosynovitis.
The best known synovial sheaths are those of the flexor apparatus of the hand, that is to say to the internal and external digitocarpal, in the fibrous band of the foot, and in the long tendon of the biceps muscle.
Therefore, we can conclude that to allow movement of the tendons within the carpal tunnel zone, each tendon is encased in a sheath.

List 4 examples of limiting factors described in the reading and label each if it would be considered an abiotic or biotic limiting factor.
Answer:
Explanation:food, water, habitat, and mate.
Limiting factors can be either abiotic or biotic. Examples: Abiotic → water, pH, radiation, salinity. Biotic → predation, competition, parasitism.
What are biotic and abiotic factors?The ecosystem is composed of living and non-living elements that interact and depend on each other. These are the biotic and abiotic factors.
• Abiotic factors are physical and chemical components of the ecosystem. These are the non-living elements.
• Biotic factors are all the living components in the ecosystem.
Biotic and abiotic factors influence the survival and reproduction of living beings.
What are the limiting factors?Limiting factors are environmental conditions that act directly on populations and individuals, limiting their distribution and growth.
These factors might be either biotic or abiotic and affect natality and mortality rate, migration, etcetera.
Limiting factors might be a result of the population density or might be dense-independent.
When talking about dense-independent limiting factors we are referring to
abiotic factors, such as temperature, pH, salinity, humidity, radiation, etcetera.natural disasters like fires, volcanic eruptions, flooding, etceterahuman impactWhen talking about dense-dependent limiting factors we are referring to biotic factors and the interactions established between species that control other species' growth.
These are, for instance,
competition, parasitism, and predation
Each species carries out a different role in these interactions.
These relationships and the results are what determine the destiny of the populations and their size.
Now, since I do not have the text, I will suggest a few examples of limiting factors. Take a look at them and then look for some other examples in your reading.

The part that is not the conducting portion of the respiratory system is the alveoli, which is in option D, as this is not a part of the conducting portion but a part of the respiratory system. So, option d is correct.
The alveoli are small, thin-walled sacs located at the end of the bronchioles in the lungs. They are responsible for gas exchange, where oxygen is taken up from the inhaled air and carbon dioxide is released into the exhaled air. While the alveoli are an essential part of the respiratory system, they are not considered part of the conducting portion. Instead, they are part of the respiratory portion, where gas exchange occurs. So, option d is correct.
