Clotting cascade refers to the series of reactions which take place simultaneously and result in blood clotting. The clotting cascade is a complex set of negative feed back mechanism which is used by the human body to maintain homeostasis. The clotting cascade can be triggered either by intrinsic or extrinsic release of chemical mediators. The reaction occur in this order:
Intrinsic factor < activation of common clotting pathway < platelet lipids are released < prothrombin < fibrinogen < fibrin formation < stabilized fibrin clot.
Two examples of anticoagulant medication that affect the pathway are heparin and warfarin
Answer:
1) 60x; 2) 150x
Explanation:
Total magnification = Power of the Ocular X Power of the objective
Power of Ocular = 15x
Power of Objective = 4x ; 10x
1)Total magnification = 15 X 4 = 60x
2)Total magnification = 15 X 10 = 150x
The ground finches adapted to have larger beaks to eat the bigger seeds in the drier seasons. This means over the years only the bigger beaked finches could survive to reproduce.
Answer:
c. individuals of a single species that live and interact in one area
Explanation:
When some organisms belonging to a single species live together in an area, they make a population. Since members of a population belong to the same species, they are able to interbreed among themselves to produce viable and fertile progeny. They have the same resource requirement and interact with each other. All the plants of <em>Mangifera indica</em> present in an area make a population. Likewise, a group of <em>Panthera tigris</em> living in a forest together makes the tiger population of that area.
There are choices for this question namely:
a) Ciprofloxacin is an antibiotic.
b) Decadron is an antibiotic.
c) Bactrim is a bronchodilator.
d) Albuterol is a bronchodilator.
<span>e) Prednisone is a corticosteroid.

The correct answers are "ciprofloxacin is an antibiotic", "albuterol is a bronchodilator", and "prednisone is a corticosteroid". Ciprofloxacin is an antibiotic in the class of fluoroquinolones, effective against respiratory infections since patients with COPD has mucus hypersecretion which predisposes the patient to respiratory infections. Other antibiotics include respiratory fluoroquinolones such as levofloxacin and moxifloxacin, cephalosporins such as cefuroxime and ceftriaxone, and beta-lactams such as co-amoxiclav. Albuterol is a short acting beta-agonist (SABA) which actions as a bronchodilator by relaxing bronchial smooth muscles. Other popular SABA is salbutamol. Prednisone is a corticosteroid which actions to prevent inflammation by blocking the arachidonic acid pathway and therefore block the formation of inflammatory mediators.
Decadron is dexamethasone which is a steroid. Bactrim is TMP/SMX which is an antibiotic.
