Answer:
C. Simple diffusion
Explanation:
Simple diffusion from a high to low concentration is the most direct method that ions or molecules can move across a cell membrane.
Through this method, no proteins are required for transport, and no energy is used.
The ion or molecule being transported directly moves across the cell membrane, without any other factors involved.
So, the correct answer is C. Simple diffusion
<span>C is the correct answer. Electrons are not in a fixed position — they float around the outside of the nucleus in a cloud. In contrast, the protons and neutrons are found inside the nucleus. Electrons are also much smaller than both protons and neutrons.</span>
Water be included in the model as a reactant and a product
<u>Explanation:</u>
- Reactants are the one that react together in a chemical equation. The product is the result formed due to the chemical reaction occurring between the reactants.
- For example if natural gas is burnt the methane and the oxygen are the reactants. The product produced due to the chemical reaction is Carbon dioxide and water as the product.
- For the production of ADP water acts with ATP to reduce Triphosphate to diphosphate. In this, it is the reactant and in chemical reaction the bonds are broken between the atoms and new bonds are produced between the products.
