A protein acts as a pump and moves calcium ions from an area of low concentration to an area of high concentration.
Answer:
Solar energy is used today in many ways. The most common form of solar energy used today are photovoltaic solar panels, which uses the sun's light to create electricity. They are commonly used as a secondary source of power.
Explanation:
The correct answer is 'Active Transport'. when the concentration of particles is higher inside the cell and yet for proper functioning we need more ions, the ions are received by the cell by the means of active transport, in which dissolved substances are moved by the help of carrier proteins with the energy released from respiration.
Well, if it gets TOO cold or TOO hot, it dies (like humans). But when it gets a bit colder then it's normal habitat, the metabolism will slow down, making it look sleepy, and sluggish. If it gets too hot, the metabolism will speed up, making it seem hyper and energetic.
