Answer:
The beaker has more water.
Explanation:
The beaker which has more water takes more time to reach the room temperature because it has more surface area than other one. If a body has less surface area then it will lose heat energy quickly and to reach its room temperature as compared to the body that has more surface area. Heat transfer depends on the materials in which it is placed and the surrounding environment. In some materials conduction of heat occurs quickly as compared to other materials.
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.
Answer:
If u live in a house or an apartment were you can put signs You can put up a sign by your window or your door something you want to tell the people about the pandemic, or you can chalk streets outside your house or in your community.
There are two ways you could look at this. If we got rid of all viruses, then less people would die. This is obviously a good thing as so many families are devastated by virus related deaths every year. However, all these extra people could lead to surplus population which, as history has shown, leads to drought, famine, and the eventual down fall of the empire/nation/etc
Change over time. I believe this is a multiple choice question, but you have not provided the options.
