All life is based on the chemical element cabon. It is essential to life.
Attached is the exercise. I found the full scheme on the internet.
For the position "a" the correct label is the pink label with glucose concentration low. This type of cotransportation transports two solutes in the same direction, being one in favour of its gradient, and another one against its gradient. In this case the one that's in favour of its gradient is the Na+, so the glucose is in low concentration outside the cell.
For the position "b" the correct label is the one with the glucose and Na+ entering the cell. This is cotransport, done by the glucose-sodium cotransporter.
For the position "c" the correct label is the pink label with glucose concentration high. This type of cotransportation transports two solutes in the same direction, being one in favour of its gradient, and another one against its gradient. In this case the one that's in favour of its gradient is the Na+, so the glucose is in high concentration inside the cell.
For sentence "1." the correct term is "down". Because the Na+ concentration is higher on the outside of the cell, the Na+ moves down its electrochemical gradient.
For sentence "2." the correct term is "against" for the reasons explained above.
Answer:
There are four stages in the water cycle
1. Evaporation
Evaporation is the process by which water changes from a liquid to a gas or vapor. Evaporation is the primary pathway that water moves from the liquid state back into the water cycle as atmospheric water vapor.
2. Condensation
Condensation is the process by which water vapor in the air is changed into liquid water. ... The phase change that accompanies water as it moves between its vapor, liquid, and solid form is exhibited in the arrangement of water molecules. Water molecules in the vapor form are arranged more randomly than in liquid water.
3. Precipitation
When we talk about precipitation, we are talking about water that is falling out of the sky, this could be rain, drizzle, snow, sleet, hail or something rarer!
4. Collection
When water falls back to earth as precipitation, it may fall back in the oceans, lakes or rivers or may end up on land.
The answer to this is Eukaryotic Plant.
