Answer: the atomic number (number of protons) order the elements.
Explanation: Each element on the Periodic Table has their own configuration of electrons. In order to have a neutral charge, there is an equal number of protons to electrons. Thus, the atomic number (number of protons) order the elements.
Answer:
b- It is a spontaneous process.
Explanation:
Passive transport is the type of transport of substances across the plasma membrane that occurs without energy expenditure and occurs spontaneously. There is no energy expenditure during passive transport because substances naturally move from the more concentrated to the less concentrated medium, ie in favor of the concentration gradient.
Substance transport occurs until concentrations inside and outside the cell are equalized.
According to this conceptualization we can conclude that the correct answer to your question is the letter B.
A.) Veins in the pulmonary circuit carry oxygen-rich blood
red blood cells are used to circulate oxygen through out the body, thus it is true.
Answer:
Biofuels, Natural Gas, Wave Energy, etc.
Explanation:
what is it? Alternative energy sources is any energy sources that is alternative to fossil fuels
Water or other molecules move down their concentration gradient without any energy.........
difference - simple diffusion uses help of transporting protein in the membrane whereas osmosis uses no help.
