Answer:
Tropomysin, calcium
Explanation:
Tropomysin is a protein that prevents muscle contraction hence acts as a contraction inhibitor. It wraps around the actin blocking the binding sites for myosin on the actin.
Muscle will only contract when they get a rush of calcium ions.
The calcium ions binds to troponin, the troponin changes its shape. The change in shape will remove tropomyosin from the binding sites allowing myosin to bind on the actin leading to muscle contraction.
Answer:
Bateria
Explanation:
In humans, the flu virus and streptococcal bacteria cause infectious diseases, and they spread from person to person. In contrast, non-infectious (abiotic) disorders in humans include health conditions which are not transmitted from person to person or caused by an infectious agent
The population would decrease because the high death rate and low other rates would lead to more deaths than births, and not many other people would be entering the country/place, so the population would decrease
