A student remarks that it is a good thing that humans discovered how to use industrial processes to fix nitrogen because this en
enyata [817]

Answer:

D. The statement is inaccurate because humans would not be able to distribute the product of nitrogen fixation from industrial processes in the same way that bacteria are able to distribute it globally now.

Explanation:

Nitrogen fixing bacteria has the responsibility in nature to trap and fix atmospheric nitrogen in ecosystems. They are very important components of the nitrogen cycle and play an important role in maintaining the balance  of nutrients in nature.

If humans discover industrial processes to fix nitrogen, the process will be unsustainable in the long run if nitrogen-fixing bacteria ever go extinct because humans would not be able to distribute the product of nitrogen fixation from industrial processes in the same way that bacteria are able to distribute it globally now across several ecosystems all over the world.

What happens to the sarcoplasmic reticulum when a skeletal myofiber is first stimulated?
Troyanec [42]

calcium is released into the sarcoplasm through gated channels

<h3>What is calcium ?</h3>

The chemical element calcium has the atomic number 20 and the letter Ca as its symbol. Calcium is an alkaline earth metal that reacts with air to create a black oxide-nitride coating. Its heavier homologues barium and strontium are most similar to it in terms of physical and chemical characteristics. It is the third most plentiful metal, behind iron and aluminum, and the fifth most abundant element in the crust of the Earth.

The most prevalent calcium component on Earth is calcium carbonate, which may be found in limestone and the fossilized remains of ancient marine life. Other calcium-rich materials include gypsum, anhydrite, fluorite, and apatite. The word "lime" comes from the Latin word calx, which was made by heating limestone.

Concentration cell based on the Ni2 -Ni cell reaction.
Alex73 [517]

Answer:

Explanation:

The missing diagram contained in this question is first attached in the image below.

The objective of this question is to determine how ions migrate when the cells are operating by assuming the solutions are composed of Ni(NO3)2.

From the information provided:

In this instance, the ions tend to move first from cathode to anode in terms of raising the concentration of Ni(2+) at the anode, resulting in the development of a dead cell. The initial concentration of [Ni(2+)] in the anode solution is 1.00 × 10⁻³ M, which gradually increases to 0.5 M, during which both the cathode and the anode possess the same concentration at the same point.

This causes Q(equilibrium constant) to equal  1 as well as log(Q) to equal 0, indicating that the cell is dead.

As a result, the cell will cease to operate, and nothing will migrate from the left to the right side.
