<span>We know that electrons are occupied on a cloud surrounding
the nucleus. So which means that the bigger the electron cloud, the bigger the
number of electrons. So in this case, since Na shrank so it lost some
electrons. And since Cl+ grew in size of the electron cloud so electron was
added to it.</span>
The part of human body that do the same job as wires and circuits is our brain . With enormous amount of nerves and computing cells , our brain has the capacity to do work like circuits . ,Not equal to them , but to some extent its quite complex
Answer:
speed = distance/ time= 45/3 = 15miles per hour
Explanation:
The answer is diffusion.
The most important mechanism that enables oxygen and carbon dioxide (but as well other small molecules such as glucose, amino acids, wastes) across capillary walls is diffusion. Diffusion is a net movement of molecules through some barrier from an area of high concentration to the area of low concentration. When blood rich in oxygen reaches capillaries close to the cell, now there <span>is </span>more oxygen in the capillaries than in the cells and by diffusion, oxygen will pass capillary walls and enter the cell. Since blood in capillaries lacks in carbon dioxide, it will easily leave the cells and enter the blood. It should be taken into consideration that capillary walls may be fenestrated, continuous, and discontinuous which can affect movement through them.
The answer is; negative…positive
In a closed circuit, electrons move from the negative node to the positive node. Electric current, on the other hand, flows from the positive node to the negative node. The flow of electrons and electric current is measured in amperes (A).
