Stalactite.
<u>Stalactite:</u>
- Often, stalagmites develop up from the cave floor, whereas stalagmites typically grow down from the cave roof.
- It's simple to distinguish between the two since stalagmites have a "G" for ground and stalactites have a "T" for top.
- Typically made of calcium carbonate, stalagmites can also be made of lava, mud, peat, pitch, sand, sinter, and amber.
- A single drop of water rich in minerals is the origin of all limestone stalactites.
- The smallest ring of calcite is left behind by the falling water drop.
- Another calcite ring is left behind with each new drop of water that develops and drops.

Answer:
Explanation:
AP Biology Question:
Scientists are testing substance  L  to determine how it enters mammalian cells in a culture. The cells maintain a   120 millimolar (mM)  intracellular concentration of substance  L . The scientists determined the rate of entry of substance  L  into the cells at various external concentrations of substance  L (10 to 100 mM)  in culture medium (Table 1).
 
        
             
        
        
        
Answer:
The hill models gravity as a driving force in the water cycle.
Explanation:
Gravity (the gravitational force that pulls objects towards the centre of the Earth) drives the water cycle.
Gravity is responsible for precipitation (rain, hail, sleet, and snow) falling downwards towards the Earth's surface. It is also responsible for water at higher points on the Earth's surface flowing downwards to the lower points on the Earth's surface.
In Carlos' model, the hill represents a higher point on the Earth's surface while the valley represents a lower point on the Earth's surface. The river, flowing downwards from Carlos' hill to Carlos' valley, demonstrates the role of gravity as the driving force of the water cycle.

During photosynthesis, the plant needs carbon dioxide and water-- both of which are released into the air during respiration, during respiration, the plant needs oxygen and glucose, which are both produced through photosynthesis
