Answer:
Option (3).
Explanation:
Pathogenesis may be defined as the process of development of the visible diseased state in the organism. The development and origin of any disease can be easily determined by the process of pathogenesis.
The pathogen should get exposure (contact) to cause a disease. Then, it should get adhere in the tissue and body of the organism. The invasion is important for the infection of the disease. Infection is the last stage in which the disease is visible. Hence, the order is exposure, adhesion, invasion, infection.
Thus, the correct answer is option (3).
Answer:
<h2>
Calcium ions</h2>
Explanation:
The actin and myosin are the myofilaments which are involved in the contraction and relaxation of the muscle. The actin is thin filaments and contains the attachment site for the myosin but the site is blocked by the tropomyosin and troponin proteins.
When calcium ions present in the muscle binds to the troponin molecules, it changes the conformation of the tropomyosin. This change exposes the attachment site of the myosin and then the myosin binds the troponin and causes Powerstroke and leads to contraction of a muscle.
Thus, Calcium ions is correct.
Answer:
personality
Explanation:
I know alot of poeple who make how they dress their perosnality.
During a windstorm, a large old tree fell in the forest. As it came down, it trapped a young sapling about 5 meters tall underneath it. The top of the
Auxin and gibberellin in the sapling's stem will cause a gravitropic response in the sapling, and its stop will grow upward even though it is held down.
