I think that the best phrase to fit into the blank is a "scientific theory".
A scientific theory is developed through experiments which use the scientific method, and a theory can be improved if additional data is available or if people provide suggestions which make the theory fit the data better.
Answer:(We breathe because oxygen is needed to burn the fuel [sugars and fatty acids] in our cells to produce energy.) What happens in the process of respiration? ... (The energy station of the cells, called mitochondria, process oxygen to power the cells. As part of the combustion process, carbon dioxide is released.)hope it helped in someway ig idk
Explanation:
Simple diffusion is the process by which a substance moves across a cell membrane from an area of high concentration to an area of low concentration. Substances that move by simple diffusion are able to diffuse directly across the phospholipid bilayer of the cell membrane. These substances are generally small and neutral, as large or charged particles cannot cross the phospholipid bilayer. Some examples of molecules that move by simple diffusion are carbon dioxide and oxygen.
Facilitated diffusion is the process by which a substance moves across a cell membrane from an area of high concentration to an area of low concentration with the aid of a membrane protein. Substances that move by facilitated diffusion are not able to diffuse directly across the phospholipid bilayer of the cell membrane. These substances are generally large and/or charged. They therefore travel through a protein channel in the cell membrane along their concentration gradient. Some examples of substances that can move by facilitated diffusion are glucose, sodium ions and chloride ions.
The similarities between facilitated diffusion and simple diffusion are:
They both involve the movement of a substance across a cell membrane along its concentration gradient (from an area of high concentration to an area of low concentration).
They are both examples of passive transport, as neither requires energy from the cell to move the substance across the membrane.
Answer:
decline: decrease
Explanation:
Transpiration is the loss of water from stomata by the process of evaporation. It occurs by the process of diffusion and is driven by the concentration gradient of water vapor. The higher the concentration gradient between air and leaf cells, the higher is the rate of diffusion of water.
On a sunny day, the rate of transpiration is higher since air is less humid and the concentration of water inside the leaf is higher. On the other hand, the air is more humid on a rainy day. The increased water vapor content of air reduces the concentration gradient between air and leaf cells. The reduced concentration gradient decreases the rate of transpiration.
