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.

which phyla do crinoids and sea cucumbers belong to?
Why did Ibrahim conclude that the dorsal spines were not used to support a hump or to regulate body
temperature?
Chemical composition of dorsal spines provides information about its function as regulation of body temperature.
The dorsal spines were not used to support a hump or to regulate body temperature because of the chemical composition of the spines. Ibrahim found that the spines were made up of bones having few blood vessels and were likely wrapped tightly in skin which can't perform the function of thermoregulation in the body.
In order to regulate temperature of the body, more blood vessels are needed and we know that in dorsal spines the structure is bony and less number of blood vessels so we can conclude that chemical composition of dorsal spines provides information about its function as regulation of body temperature.

Explanation:

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.

What are the roles of the nucleus, cytoplasm, mitochondria, and the cell membrane in eukaryotic cells? in your own words nothing from the internet
Answer:
What are the roles of the nucleus, cytoplasm, mitochondria, and the cell membrane in eukaryotic cells?
Explanation:
1.The cell membrane holds the cell's internal contents from its environment
2.the nucleus, the cell's "brain", holds the cell's DNA in the form of chromosomes, and makes protein codes that tell the other organelles to function in a certain way once the codes are made into literal proteins and passed around the cell
3.The cytoplasm is the gelly fluid inside the cell. It is the place for chemical reaction, and provides a place where other organelles can operate within the cell properly, and the cytoplasm keeps the cells from moving around.
4. The main job of the mitochondria is to convert nutrients into energy through cellular respiration, making ATP. the mitochondria are known as the powerhouse of the cell. In addition to supplying energy, the mitochondria is involved in a range of other processes,like signalling, cellular differentiation, cell death, as well as control of the cell division cycle and cell growth.

is a grasshopper a herbivore carnivore or omnivore
Grasshoppers are well-known plant-eating insects that are herbivores.
Their typical diet consists of a variety of plant material such as grasses, leaves and plant stems. They chew and eat plant matter using their powerful jaws. Grasshoppers' digestive tracts contain symbiotic microbes that help them digest cellulose, a complex carbohydrate found in plants.
Although the primary trait of grasshoppers is herbivory, it is important to note that under certain circumstances, particularly when resources are limited, some species may engage in cannibalism. However, they are clearly classified as herbivores because of their overall diet and ecological function in the ecosystem.

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.
