The calcium ions released into the cytosol during excitation of skeletal muscle bind to

emmainna [20.7K]

Answer:

Bind to the protein complex troponin.

Explanation:

Excitation of skeletal muscle caused by the calcium ions. During excitation of skeletal muscle, after calcium ions released into the cytosol, they bind to the protein complex known as troponin and causing substitutions in the protein complex.

These alterations permit protein to push out from the myosin-binding sites on the actin filament.

The molarity of the lake water is 0.00001 M and the pH of lake water is 5.

The lake water is acidic.

Explanation:

Data given:

molarity of base solution Mbase = 0.1 M

volume of the base solution Vbase = 0.1 ml or 0.0001 litre

volume of lake water Vlake = 1000ml or 1 litre

molarity of the lake water, Mlake = ?

Using the formula for titration:

Mbase X Vbase = Mlake X

Mlake = $\frac{Mbase X Vbase }{Vlake}$

Putting the values in the equation:

Mlake = $\frac{0.0001 X 0.1}{1}$

Mlake = 0.00001 M

The pH of the lake water will be calculated by using the following formula:

pH = - $log_{10}$ [ $H^{+}$ ]

pH = - $log_{10}$ [ 0.00001]

pH = 5

A naoh (aq) stock solution was created by dissolving 3.88 g naoh in water to create a 100.00 ml solution. what is the concentrat

Bess [88]

0.0381g/mL will be concentration of this solution

The ratio of a solute—a substance that dissolves—to a solvent—a substance that does not dissolve—determines the concentration of a solution in chemistry. C = m/V, where C is the concentration, m is the mass of the solute dissolved, and V is the overall volume of the solution, is the accepted formula.

How to reach the solution?

First find for the density of NaOh which is 2.13 g/cm3

3.88 ÷ 2.13 = 1.82mL

100mL + 1.82mL = 101.82mL

3.88 ÷ 101.82mL = 0.0381g/mL

More about NaOh:

The extremely adaptable chemical sodium hydroxide (NaOH), sometimes referred to as caustic soda or lye, is employed in a range of manufacturing processes. A byproduct of the manufacturing of chlorine is sodium hydroxide. Numerous items that are used on a daily basis, including paper, metal, drain and oven cleansers for industry, soap, and detergents, are made with sodium hydroxide.

What happens to the luminosity of stars in the main sequence as temperature decreases

sladkih [1.3K]

As the size of a star increases, luminosity increases. If you think about it, a larger star has more surface area. That increased surface area allows more light and energy to be given off. Temperature also affects a star's luminosity.
