Mouth/nose inhale air, filter dust/ pathogens in air (for nose only)
Pharynx: when food is swallowed, it passes through the pharynx and enter the oesophagus
Larynx: it produces sound by vibration when air passes through it
Trachea: allow air to enter the lungs
Bronchi: there are two of them. Each of them are larger than bronchioles, smaller than trachea. Same function as trachea
Bronchioles: there are numerous of them. Each of them are smaller than bronchus. They have air sacs attached to it.
Alveoli/ air sacs: site of gas exchange. There are numerous of them and they are tiny to provide a large surface area for gas exchange
Hope this helps

Trace minerals are needed in much smaller amounts than major minerals, but they are just as essential for good health. They are
kow [346]

Answer:

1. Heme iron is found in animal foods like meat and poultry, whereas the nonheme iron form is found in plant foods like grains and vegetables.

2. The metal and trace mineral copper is part of several enzymes and proteins.

3. Adequate zinc is important for maintaining a healthy immune system and may aid in wound healing.

4. Selenium acts as an antioxidant and aids in thyroid function.

5. Fluoride is not considered essential, but it is very important for maintaining strong, healthy teeth.

6. The deficiency disease goiter was much more common before iodine was added to salt in the United States.  

7. Manganese acts as a cofactor for a variety of enzymes and also plays a role in synthesis of bone.

Explanation:

  • Iron: The major difference between the iron provided by animals Heme Iron) and plants (Nonheme iron) is that the heme iron is better absorbed by the organism. There are several mechanisms in the intestine that improve the heme iron absorption that is used for producing red globules for the organism. Carnic products such as red meat, fish, and poultry are rich in heme iron. Vegetables contain nonheme iron, which is harder to assimilate by the organism and thus its absorption is lower.
  • Copper: Is an essential element for life that intervenes in the electronic transport chain, being part of the IV complex. It is also part of the enzyme that catalyzes the decomposition of the superoxide ion, toxic for living organisms. Copper is an element of the hemocyanin which is a protein present in some invertebrates, with a function similar to hemoglobin.
  • Zinc: This metal has many uses in industry. In health, it is used in dietetic supplements, to maintain its correct levels. It is also useful in wound healing, in reducing duration and severity of colds, and has antimicrobial properties that help to relieve gastroenteritis symptoms. It is added in solar protectors, in toothpaste for good breath, and in the shampoo to deal with dandruff problems.
  • Selenium: It is an antioxidant component of some enzymes that act in the elimination of substances with reactive oxygen. Besides this element is important in the regulation of the thyroid function.
  • Fluoride: Although it lacks if metabolic activity in mammals and superior plants, some plants and marine sponges can synthesize a fluor compound as a poison for protection. Fluoride is used in many kinds of toothpaste because it interacts with calcium to create a harder and more stable fluorapatite matrix that protects the teeth.
  • Iodine: Is an essential element that intervenes in numerous functions in the organism. The only entranceway of the element is by ingesting it with a recommended diet. Iodine lack might cause several problems in health such as thyroid problems or goiter.
  • Manganese: This metal is an essential element that exists naturally in the ground and water. For animals, the manganese is an essential component of enzymes that are used in carbohydrates, fat, and protein metabolism. Manganese is a cofactor for numerous enzyme activities. It is also important in bony tissue development and reproduction.

Adjacent plant cells have narrow channels called plasmodesmata that pass through the cell walls of the connected cells and allow
Zepler [3.9K]
<h2>Functions of plasmodesmata</h2>

Explanation:

  • They allow the movement of cells to cells for cytoplasmic connection between different cells
  • Plant cells, encompassed as they are by cell dividers, don't get in touch with each other through wide stretches of plasma film the manner in which creature cells can. Be that as it may, they do have particular intersections called plasmodesmata (solitary, plasmodesma), places where a gap is punched in the phone divider to permit direct cytoplasmic trade between two cells.  
  • Plasmodesmata are fixed with plasma film that is consistent with the layers of the two cells. Each plasmodesma has a string of cytoplasm stretching out through it, containing a much more slender string of endoplasmic reticulum.
  • Particles beneath a specific size (the size rejection limit) move unreservedly through the plasmodesmal channel by latent dissemination. The size avoidance limit changes among plants, and even among cell types inside a plant. Plasmodesmata may specifically enlarge (extend) to permit the section of certain huge atoms, for example, proteins, in spite of the fact that this procedure is inadequately comprehended.
