Which sub-atomic particle is counted to learn the atomic number of that element?

1 answer:

6 0

Helium, with two protons, will have two electrons. In the chemical classroom, the proton count will always be equivalent to an atom's atomic number. This value will not change unless the nucleus decays or is bombarded (nuclear physics). Figure \(\PageIndex{1}\): The periodic table of the elements.

How do the heart and lungs work together

MrRa [10]

Heart and lungs works hand in hand. Not only that they are close to each other but they also work to make sure that body gets enough oxygen that it needs to live. It is the heart that pumps blood through the body it passes through the lungs. then it is the job of the lungs to supply oxygen together with the blood that heart pumps.

Assume it takes Venezuela 3 hours to produce a batch of apples and 7.5 hours to produce a batch of pumpkins, and it takes the Un

IrinaK [193]

Answer:

Venezuela

Explanation:

In economics, absolute advantage refers to the ability of an entity to produce a good or service at a lower cost/time per unit given the same resources as another entity.

In other words, given the same quantity of input and time, an individual, a company, or a nation that produces greater output over the other has an absolute advantage at producing such an output.

<em>Hence, if it takes Venezuela 7.5 hours to produce the same batch of pumpkin that the United States produces in 8.5 hours, then, Venezuela has an absolute advantage in producing pumpkins over the United States.</em>

4 a muscle cramp is a sudden, painful contraction of a muscle, during which movement is difficult. What is happening at the cell

stiks02 [169]

In the case of the muscular cramps, the muscle contraction starts with the generation of the action potentials from the brain. The action potential causes the release of the calcium ions movement out of the sarcoplasmic reticulum (storage site of calcium). The calcium released in this process causes the contraction of the myofibrils with the help of the ATP molecules. Meanwhile, the calcium is pumped back to the sarcoplasmic reticulum through the fast calcium pumps.

The contraction of one muscle cell generate the action potential in neighboring muscle cells. When the generation of the action potential is stopped, the sarcoplasmic reticulum relaxes as well as the muscle is relaxed. The fast calcium pump is powered by a sodium gradient, and the calcium influx is a result of fast outflux of the sodium ions from the sarcoplasmic reticulum.

In case, the sodium ion is less, the calcium pumps cannot be powered, the calcium ion would remain in myofibril, as a result, the muscle would be contracted for a longer time and this result in cramps. The muscle in this case, would be relaxed by the ATP instead of sodium gradient. So, it can be concluded that the muscle cramps are caused when the muscles are not able to relax properly.
