Answer:
In birds, air flows through the lungs in a unidirectional manner through a bronchial system that is made up of primary bronchi, secondary bronchi, and tertiary bronchi called parabronchi, which are the functional units of gas exchange.
Explanation:
The respiratory system of birds has peculiar characteristics both in its structure and in the way its breathing is carried out. The respiratory system of birds is made up of the lungs, air sacs, trachea, bronchi, blood vessels and nerves. Compared to mammals, birds lack structures such as the ethmoid labyrinth and the thoracic cavity is not limited by the diaphragm. When the bird breathes in, the air is drawn directly from the bronchi to the posterior air sacs, where the air is stored. As the posterior air sacs expire they deflate, this causes the air to pass into the lungs, where oxygen is absorbed. The consumed air (which contains carbon dioxide harmful to the organism) is then lodged in the anterior air sacs, and the animal inhales fresh air again to send to the posterior air sacs. After exhaling the consumed air expelled from the anterior sacs (to the outside) and bringing fresh air from the posterior air sacs to the lungs. This dynamic in the respiratory system of birds, allows air movements unidirectionally through the lungs generating a higher oxygen content.

What are Krebs cycle inputs and outputs?
Answer:
see below image:
Explanation:
inputs + their outputs listed in the image
The Krebs cycle continues when acetyl-CoA (2-carbon molecule) and oxaloacetate (4-carbon molecule) combine to form citrate (6-carbon molecule). Citrate is then converted into cis-aconitate, which is then converted into isocitrate. Following this step, one of the carbon atoms separates and is released as CO2.
What is Krebs cycle?The tricarboxylic acid (TCA) cycle, also known as the Krebs cycle or the citric acid cycle, is the primary source of energy for cells and an essential component of aerobic respiration.
The cycle converts acetyl coenzyme A (acetyl CoA available )'s chemical energy into the reducing power of nicotinamide adenine dinucleotide (NADH).
The Krebs cycle is powered by lipids (fats) and carbohydrates, both of which produce the molecule acetyl coenzyme-A. (acetyl-CoA).
This acetyl-CoA reaction is the first in an eight-step sequence of reactions known as the Krebs cycle, which takes place entirely within the mitochondria of eukaryotic cells.
The net energy output of glycolysis through the Krebs cycle for one glucose molecule is 4 ATP, 10 NADH + H+, and 2 FADH2.
Thus, these are the chief inputs and outputs of Krebs cycle.

Large deposits of Rock Gypsum and Rock salt have been found in Upstate NY. What does this tell you about the environment of Upstate NY in the past?
Answer: There must have been a body of water there previously, maybe prehistorically.
Explanation: Gypsum forms when the right materials in a body of water come together and water evaporates quickly.
Gypsum is an evaporite, which means its crystals form during the evaporation of water. Gypsum forms whenever evaporation crystallizes the necessary minerals. In the case of "desert roses" gypsum crystals found around the world in arid sites, formation occurs with evaporation as the level of the water table changes. Gypsum can also be formed diagenetically by oxidation. This chemical reaction occurs when oxidation of existing sediments causes gypsum to form and replace other minerals in the sediments.
Huge gypsum deposits called beds were formed when ancient tropic seas became concentrated through evaporation. Gypsum crystals formed in the mineral saturated sea brine and sank to the ocean bed.

There are 4 different (main) types of tissue: Muscle, Connective, Nervous, & Epithelial.
(if you need a different example here's one): The Doctor did surgery on the patient to see what was wrong with her tissue.
Kaya had an organ transplant. She went to the doctor a week later, and the doctor did a blood test. Her lymphocyte count
had increased. She went to the doctor a month later for the same test, and her lymphocyte Count was higher. What is the
best explanation as to why her lymphocyte levels were increasing?
O Kaya was given antibiotics to prevent infections.
O Kaya's antigens were attacking the tissue.
O Kaya was not tissue typed prior to her surgery, and her body is mounting an immune response.
Kaya took her immunosuppressant drugs weekly, which increased her lymphocyte count?
The best explanation for why Kaya's lymphocyte levels were increasing is Kaya was not tissue-typed prior to her surgery, and her body is mounting an immune response. Therefore option 3 is correct.
Lymphocytes are a type of white blood cell that plays a crucial role in the immune response of the body. They are responsible for recognizing and targeting foreign substances, such as antigens, to protect the body against infections and diseases.
In Kaya's case, her lymphocyte levels increased both a week and a month after the transplant. This suggests that her immune system is responding to the presence of the transplanted organ.
The increased lymphocyte count indicates an ongoing immune reaction, which is typically characterized by the proliferation and activation of lymphocytes.

What best describes the radiation emitted from the sun?
High doses of radiation are used in radiation therapy, also known as radiotherapy, as a cancer treatment to eradicate cancer cells and reduce tumor size.
What is Radiation?As with x-rays of your teeth or shattered bones, radiation is utilized at low doses in x-rays to see inside your body.
Radiation therapy damages cancer cells' DNA, which either kills them or limits their growth at high dosages. Cancer cells that have DNA damage that cannot be repaired either cease proliferating or die. When the injured cells expire, the body degrades and eliminates them.
Radiation therapy does not instantly eradicate cancer cells. Before cancer cells experience enough DNA damage to cause them to die, days or weeks of treatment are required. After radiation therapy is finished, cancer cells continue to perish for a few weeks or months.
Therefore, High doses of radiation are used in radiation therapy, also known as radiotherapy, as a cancer treatment to eradicate cancer cells and reduce tumor size.
