The answer is (b.) Fine Pebbles have a higher threshold velocity than sand.
Given the fact that fine pebbles' diameter size are usually 2.0 to 5.0 mm which is bigger compared to sands which diameter is usually measure only at 0.05 to 2.0 mm, thus fine pebbles have higher threshold velocity than sand. In Geophysics, threshold velocity refers to the minimum velocity of a particle such as pebbles and sand to move by the cause of wind or water. Therefore, the higher threshold velocity is the fine pebble since it is bigger.
Answer:
yes, because Water is very important to the human body. Every one of your cells, organs and tissues use water to help with temperature regulation, keeping hydrated and maintaining bodily functions.

To prevent this type of cancer, it is recommended to have a balanced diet, to practice safe sex and to have an annual Pap test.
The concentration gradient will be in the direction from the cell to the outside of the cell .
<h3>What is concentration gradient and how the direction is from inside to the outside ?</h3>
- Concentration gradient will be from inside of the cell to the outside of the cell that is from high concentration to the low concentration.
- The concentration of substances inside the cell if given to be more than the concentration of the substance inside the cell.
- We have always studied that the direction of concentration gradient is from high to low.
- Since the concentration inside is high so the direction will start from the higher concentration.
- To the place where concentration is low that is outside of the cell.
