Explanation:[14/12, 12:09 pm] Samson Tutor: There are many factors that will cause the spread of color
1) Kinetic theory of particles(Brownian motion)
2) Gravitational force acting on the colored substance
3) Density....since their density varies
Etc
[14/12, 12:10 pm] Samson Tutor: For 1) there is constant collision between the particles of the liquid and the water(especially in an haphazard motion) hence there will be transfer of momentum between the particles of the colored liquid and water.

Organelle, cells, tissues, organs, organ systems, organisms, populations, communities, ecosystem, and biosphere. These have been arranged from the smallest to the largest. The biosphere is the largest level of organization while the organelle is the smallest. However, the basic form of life begins with the cell. Many cells together form a tissue and several tissue form an organ.
Answer:
C. energy can neither be created nor destroyed
Explanation:
The law of conservation of mass states that in a chemical reaction mass can neither be created nor destroyed. Similarly, the law of conservation of energy states that the amount of energy in an isolated system is conserved ie. the amount of energy can neither be created nor destroyed, but instead changes form.
