What is the primary advantage of multiple researchers obtaining the same result?
RoseWind [281]

Hello!

The primary advantage of multiple researchers obtaining the same result is the conclusion is likely to be more credible when they are independently verified. As the work done by them gives the same result, it can be easier to believe.

Which of the following chemicals opens us binding sites allowing muscle filaments to connect to each other? Select one:
HACTEHA [7]

Answer:

The correct answer will be option-D.

Explanation:

Calcium plays an important role in muscle contraction as they are released from the sarcoplasmic reticulum after they receive electric impulse.

Calcium triggers the muscle contraction cycle as these calcium ions bind to the troponin-tropomyosin complex. This binding exposes the myosin-binding site on the actin on which high energy myosin binds and cross-bridge is formed.

This cross-bridge formation causes the contraction of the sarcomere and therefore muscle contracts.

Thus, option-D is the correct answer.

The concentration of a biomolecule inside a rod-shaped prokaryotic cell is 0.0037 m. calculate the number of molecules inside th
Talja [164]

First, let calculate the volume of the rod shaped-bacteria:

S = length of the bacteria * surface of its side = 4.1 * (0.45 *0.45 * 3.14) = 2.6 µm3

Now, let's convert the moles into molecules (with Avogadro's law):

0.0037mol/L = 0.0037 * 6.023 *10^23 = 2.22 *10^21 molecules / L

Now let's convert The volume and the concetrnation into µm3 (molecules / µm3)

1 L = 1 dm3 = 1000 cm3 = 1000000 mm3 = 10^9 µm3

so 2.22 *10^21 molecules / L = 2.22 10^ 12 molecules / µm3

The answer is  2.22 10^ 12 molecules / µm3
