Stars are formed in clouds of dust and gas (nebulae.) Nuclear reactions at the center (core) of stars gives enough energy to make them shine brightly for many, many years. The exact l<span>ifetime of a star depends on its size.</span>
Wait what please explain I'm so lost
Explanation:
Many proteins can move within the plasma membrane through a process called membrane diffusion.
This concept of membrane-bound proteins that can travel within the membrane is called the fluid-mosaic model of the cell membrane.
Answer:
Depolarization
Explanation:
Depolarization is a change in cell's membrane potential such that the inside of the membrane is made less negative relative to the outside by moving the voltage in the direction of zero Voltage.
Action potentials occur whenever a depolarization increases the membrane voltage to a threshold, which usually has a membrane potential value of -55mV.
Yes. An example is Methyl Alcohol, absorbs water. (CH3OH) Two elements can form different types of bonds and end up with different compounds. There is a small amount of elements. There is a bigger number of compounds.
