1. The branches of the bronchial tree ultimately ends at the alveoli. Bronchial tree consist of bronchi, bronchioles, and alveoli. Bronchi are formed as the lower part of the trachea divides into two tubes. Bronchioles are smaller tube divisions of the bronchi. It walls contain smooth muscle and no cartilage. Alveoli are tiny ends of the alveolar ducts, which functions as the site for gaseous exchange.
2. Blood flows from the left atrium; mitral (bicuspid valves), the left ventricle, aortic valve, aorta, veins and heart, right side of the heart, superior and inferior vena cavae, right atrium, tricuspid valve, right ventricle, pulmonary valve, pulmonary trunk, pulmonary artery, lungs, pulmonary veins, then back to the heart...
3. Arteries and the veins differ in structures and they way they functions; Arteries carry oxygenated blood away from the heart to the body (except pulmonary artery) while veins carry deoxygenated blood back from the body to the heart (except pulmonary veins). A structural differences includes; the veins contain valves while arteries lack. Arteries have narrow lumen while veins have wide lumen. Lastly, blood carried by veins has higher pressure compared to blood carried in vessels.
4. The circulatory and respiratory systems work together to circulate blood and oxygen throughout the body. Air moves in and out of the lungs through the trachea, bronchi, and the bronchioles. Blood moves in and out of the lungs throgh the pulmonary arteries and veins that connect to the heart.
5. The cartilage rings of the trachea They are strong but flexible tissues which support the trachea or the windpipe while still allowing it to move and flex during breathing. Additionally these cartilage rings are C-shaped to provide room for the esophagus, which lies along the back side of the trachea.
6. Functions of the larynx includes; To protect the airway from choking on material in the throat to regulate the flow of air into our lungs The production of sounds used for speech Larynx is part of the respiratory system and is located between the pharynx and the trachea. Humans use larynx to breathe, talk and swallow.
7. Structures that make up the pathway of air through the respiratory system starting with the external nares; We start with; External nares, nasal cavity, internal nares, nasopharynx, laryngopharynx,oropharynx, larynx, trachea, primary bronchus, secondary bronchus, tertiary bronchus, bronchiole, terminal bronchiole, respiratory bronchiole, alveolar duct, alveolar sac and alveolus.
The proteins are one of the important biomolecules which are directly coded by the genetic material of an organism.
The proteins are composed of the amino acids which possess, an amine group, a carboxylic group and an attached side group called the R group.
It is the R group of an amino acid which determines whether the amino acid will a polar or a non-polar amino acid molecule thus it determines the properties of the amino acid in terms of chemical properties. The R side group are involved in the formation of bonds with the substrate of the environment and the tertiary structure of the proteins.
Thus, the presence of different R group is the key difference in 20 amino acids.
Various day to day use item are made because of direct from a huge amount of different microorganisms. microscopic organisms, molds, or a blend of these. Microorganism which are utilized in food creation such as alcohols, bakery products and esters are formed with fermentation.
1. Drinks like brew and wine ' - Saccharomyces cerevisiae
2. Cheese: Penicillium roqueforti and camemberti
3. Soy sauce: by utilizing aspergillus species particularly A. oryzae
4 Bread and pastry shop items : Saccharomyces cerevisiae or Yeast by producing Co2 by the process of fermentation.
5. Fermented milk items : Lactobacillus, Bifidobacterium and lactococcus.
The correct option is C. Lantana is a tropical evergreen shrub which is usually cultivated as ornamental flowers. It is a plant that threatening livestock especially in Australia. The signs of lantana poisoning in livestock include: excessive skin sensitivity to sunlight, liver damage, yellow coloration of the white part of the eyes, reddening of the eyes, swelling of the ears, etc. If the poisoning case is severe, the animal death will occur between two to four days, but generally, untreated animals usually die within one to three weeks.
