Atelectasis: Atelectasis is a complete or partial collapse of the entire lung or area of the lung. It occurs when the tiny air sacs (alveoli) within the lung become deflated or possibly filled with alveolar fluid. . General anesthesia is a common cause of atelectasis. It changes your regular pattern of breathing and affects the exchange of lung gases, which can cause the air sacs (alveoli) to deflate.
Conditions when atelectasis occurs: There are four primary causes of atelectasis: hypoventilation, airway obstruction, airway compression, and adhesions.
Hypoventilation
Hypoventilation, or breathing at an abnormally slow rate, is common during surgery, especially with general anesthesia, or when a person is placed on a respirator. The very act of shallow breathing prevents air from getting to the alveoli, causing the air sacs to deflate and collapse.
Airway Obstruction
Airway obstruction may be caused when something blocks a passage either inside the lung (like a mucus plug or a foreign object) or outside of the lungs (like a tumor which presses on the airway and causes obstruction).
Airway Compression
Compression of the airways is often caused by the buildup of fluid in the space surrounding the lungs.
Answer: Option A) A-C-T-T-G
Explanation:
The base sequence on a strand of DNA is usually paired to specific complimentary bases. These specific pairings are as follows:
Adenine (A) pairs with Thymine (T)
Guanine (G) pairs with Cytosine (C). So when you find A replace with T, so also replace C with G and vice versa.
Thus, the complimentary sequence of the T-G-A-A-C DNA strand is A-C-T-T-G
I'm pretty sure your answer is correct :)
Answer:
Eukaryotic cells are plants, animals, protists, fungi. Their genetic material is organized in chromosomes. Golgi apparatus, Mitochondria, Ribosomes, Nucleus are parts of Eukaryotic Cells.
Animals such as cats and dogs have eukaryotic cells.
Plants such as apple trees have eukaryotic cells.
Fungi such as mushrooms have eukaryotic cells.
Protists such as amoeba and paramecium have eukaryotic cells.
Insects have eukaryotic cells.
Humans are composed entirely of eukaryotic cells. Related Links: Examples.
Explanation:
Bacterial strains, especially Actinomycetes have been used in biotech production and drug discovery for years. Genetic methods now open the field of combinatorial biosynthesis that has improved impressingly in the past couple of years. Also, the productivity of yeast and other fungi in a variety of different processes has improved significantly since genetic methods have been introduced. In addition, a number of recent works considerably widens the potential of plant biotechnology. This review covers examples describing the use of prokaryotic cells and plant cells in biotech production.
Hope this helps! ^^
