an organelle that releases energy for metabolic activity in a nerve cell is the what
the mitochondria
Answer:
N/m2
Explanation:
Shear stress on cells lining the walls of the blood vessels is equal to
20 dyne/cm2
In terms of Newton/square meter, shear stress is equal to
N/m2
Shear modulus is equal to shear stress divided by shear strain
Thus, shear modulus is equal to
N/m2

Explanation:
Capillary action pulls water into the root of a tree while the forces of cohesion and adhesion continually move the water up the tall tree.
Water is a polar molecule. Strong hydrogen bonds hold the water molecules together. This is a kind of dipole - dipole interaction and it accounts for the cohesive forces in water.
The forces of adhesion bind water to other surfaces. In the case of plants, the adhesive forces facilitates the interaction of water with the xylem cells.
Water enters into the roots of plants by capillary action. Capillary action alone is insufficient to move the water up the tree.
Hence, the forces of adhesion and cohesion, acting together can help water molecules to move up the top of a tall tree.
In photosynthesis, the light-dependent reaction takes place on the thylakoid membranes. The inside of the thylakoid membrane is called the lumen, and outside the thylakoid membrane is the stroma, where the light-independent reactions take place.
The "light-independent" or dark reactions happen in the stroma of the chloroplasts. This is also known as the Calvin Cycle.
