In the case of chronic bronchitis or chronic inflammation of the airways, cyanosis or the bluish discoloration of the skin results from the reduced levels of oxygen in the blood. With reduced oxygen levels, the blood in the arteries will not be bright red in color but rather be brownish just like venous blood and this reflects in the skin as bluish in color.
These cells are called dependent cells
This is true because when the temperature is high, the particles move accordingly and move fast. This is why you see water boiling fast instead of slow.
a). Calcium ion and ATP
Explanation:
The excitation and contraction of the muscles takes place by Action potential creation.
The muscle contraction is initiated when calcium ions binds to troponin. The binding of calcium with protein complex troponin changes the configuraton to make actin sites active for ATP binding. This binding causes myosin to reach the state of high energy ( excitation), in which myosin head gets detach from the active site.
The dependent variable is Salt and Water
Because salt is an ionic compound. Namely hydrophilic compounds, meaning compounds that like water.
<h2>Further explanation
</h2>
Water dissolves NaCl by hydrating and stabilizing its ions (Na + and Cl-), weakening the electrostatic interaction between the ions so as to prevent the formation of ionic bonds to form NaCl crystals.
The dissolution process occurs through the replacement of hydrogen bonds between biomolecules with one another by hydrogen bonds between the biomolecules and water so as to prevent electrostatic interactions between biomolecules.
