When a calcium ion binds to troponin:
guapka [62]

Answer:

Option (A).

Explanation:

Muscle contraction may be defined as the physiological process of the activation of tension generating sites that occur within the muscle fibers. Actin, myosin, troponin and other proteins are important for muscle contraction.

The calcium ion is important for the muscle contraction. The binding of calcium with troponin causes the movement of tropomyosin out of the grooves between the actin molecules during muscle contraction.

Thus, the correct answer is option (A).

Imagine you were going to build a “green” building. What features would it have? What would it look like? How would it harmonize
9966 [12]

Answer:

Green building is a modern concept in architecture by means of which it is aimed at construction developments that are not invasive with the environment, or that affect the ecosystem in which they are built as little as possible, with the aim of leaving future generations an intact environment worth living in.

Thus, for a construction to conform to this concept, it must follow the following parameters:

-The construction must adapt to the natural environment, and not this to the construction.

-It has to be resource-efficient. Furthermore, the materials used must not be exploited indiscriminately or causing damage to the environment.

-The external area of the building must respect the natural patterns of the area where it is built, favoring a harmonic view between the building and the surroundings.

-Use of clean and renewable energy to supply the building.

Contractions per M
Andreyy89

To make Paramecium Contractile vacuole concentration graph useful the salt concentrations descriptions should replaced with actual values.

Thus, option "A" is correct.

What is Paramecium Contractile vacuole

"It is a sub-cellular structure (organelle) involved in osmoregulation."

<h3>What is a graph?</h3>

"A diagram (such as a series of one or more points, lines, line segments, curves, or areas) that represents the variation of a variable in comparison with that of one or more other variables."

<h3>What does the graph in the given question depict?</h3>

It shows that the Paramecium Contractile Vacuole concentration per minute decreases as salt concentration increases.

But the concentration of salt is not mention in quantity so its not clear what are the lowest and highest concentration affecting Paramecium Contractile Vacuole.

Hence, the Paramecium Contractile Vacuole concentration graph can be more useful if the actual values of salt concentration will be mentioned.
