statocytes, organelles do plants have in their roots that helps them to sense gravity, correct answer is B.
what are statocytes ?
In higher plants, statocytes are the cells which sense gravity. They contain amyloplasts-statoliths, amyloplastic organelles which are filled by starch or sediment at the bottom of the cells. Coleoptiles, shoots, and inflorescence stems all have an elongating area that really is home to statocytes.
how do they help in sensing gravity ?
When the plant is reoriented in the gravity field, the starch-filled plastids (also known as statoliths) in the statocytes, that are highly polarized cells, fall to the physical bottom.
Hence, statocytes help in sensing gravity.

Answer:
B. equilibrium
Explanation:
Equilibrium is a term that refers to the condition that exists when no change in concentration results from diffusion.
At equilibrium state, the system is at rest or in motion.
- The rate of forward processes is equal to the rate of the backward process.
Concentration is the amount of solute found in a solution.
Osmosis is the movement of solvent through a semi-permeable membrane.
Randomness is the degree of disorderliness of a system.
A mouse would be a fossil fuel first, since the fish would be in water it would have some source of living thing.
The correct answer is option (D) A sandwich is digested and converted to carbon dioxide and water.
Digestion is a catabolic process of breakdown of complex food substances into simpler nutrients releasing energy. In the process of digestion of a sandwich, the carbohydrates are broken down into simpler sugars in presence of enzymes releasing water, carbon dioxide and energy in the form of adenosine triphosphate (ATP). This ATP is the reserved energy currency and also used for the growth, repair and replacement of cells.
