Colloidal solutions: Colloidal solutions are heterogeneous systems and have the size of dispersed particles lying between 1 nm-1000 nm (i.e. 10-9-10-6 m).

Suspensions: Suspensions are also heterogeneous system and have still larger particles. The size of particles present in a suspension is more than 1000 nm (i.e., >10-6m). These particles are either visible to naked eye or can be seen under a microscope.

True solutions: True solutions are homogeneous system and have the size of dispersed particles less than 1 nm, i.e. 10-9. The particles of solute present in a true solution are either single molecules or ions and are homogeneously distributed throughout the solutions.

Algal blooms likely result from a combination of environmental factors including available nutrients, temperature, sunlight, ecosystem disturbance. This result in excess of nutrients (phosphorus and nitrogen) into water and higher concentrations of these nutrients in water cause increased growth of algae and green plants. This ultimately lead to death of aquatic plants and animals.

  • It fills the space inside the organs, and supports internal organs.
  • It helps in repair of tissues.
  • It is found between the skin and muscles, around blood vessels and nerves and in the bone marrow.

ADIPOSE

  • They are the Fat storing tissues, which are filled with fat globules
  • These tissues are found below the skin and between internal organs.
  • Due to the storage of fats, it acts as an insulator.

COMPACT BONE

  • It forms the framework which also anchors the muscles and supports the main organs of the body.
  • It is a strong and nonflexible tissue.
  • Bone cells are embedded in a hard matrix that is composed of calcium and phosphorus compounds.
