1. hydrogen atoms crash together
Hydrogen atoms (or protons) fuse within the Sun core and fall apart.
2. helium atoms are formed
Helium atom is a product of the proton-proton fusion and this process occurs through a series of steps.
3. an enormous amount of energy is released
The transformation that occurs after the fusion results in a release of huge amount of energy that keeps the sun hot. Energy is radiated out from the core of the Sun
4. energy travels to Earth in the form of light energy and heat
This energy is called The Solar energy to the Earth because it hits the surface of the Earth itself.
5. plants will use energy from the sun to make their own food
Plants are phototrophic organisms that transform the light energy into usable energy for their metabolism.
In a research, the independent variable is the one which causes a change in the dependent variable. In this case, the nurse visit in hoped to cause reduction of doctor visits. That means the doctor visit is dependent variable and nurse visit will be the independent variable<span>.</span>
Mitosis creates two identical cells and is necessary for growth, development and wound healing
Answer:
Simple Diffusion.
Explanation:
The plasma membrane is known as the selectively permeable membrane as they allow the movements of some selected particles only. The movement are facilitated diffusion, active transport and passive transport.
Water molecules are polar in nature. They can pass through the plasma membrane from its region of the higher concentration towards its region of the lower concentration. They move directly through the simple diffusion and does not require any protein or energy molecule to pass through them.
Thus, the answer is simple diffusion.
