Answer AND Explanation:
Classification is the orderly arrangement of organisms into groups based on their similarities. The modern method of classifying organisms was devised by Carolus Linnaeus. The characteristics used include:
- Anatomical structure- whether the organism is prokaryotic or eukaryotic
- Biological processes for example photosynthesis in plants and production of hormones.
- Cell structure
- Body type- unicellular or multicellular
- Mode of nutrition- heterotrophic or autotrophic
Delta and it is called this because it looks like the Delta symbol
Answer:
Although hydroelectricity is the least expensive energy source to generate electricity but still it is not used by most of the companies as it changes the normal flow of water,affects aquatic organisms,hamper fish habitats etc.
Explanation:
As hydroelectricity is fully depend upon water flow so it may create several consequences like drought,or another natural calamity may affect potentially.This may also affect the aquatic organisms that are fully depend on aquatic body.
Moreover, there are limited reservoirs for hydroelectric power plant .Only few are functional.

Answer:
1. Isotonic
2. Hypotonic
3. hypertonic
4. hypotonic
5. Hypertonic
6. Hypotonic
Explanation:
Tonicity refers to the amount of the solute concentration dissolved in the solution which determines the direction of the diffusion across the semipermeable membrane.
There are three types of tonic solutions formed on the basis of solute concentration which are:
1. Isotonic solution: When the solute concentration is the same across both the sides of the semipermeable membrane. When a cell is placed in isotonic solution it remains in the same state as no movement of water is observed as in option 1.
2. Hypertonic solution: The solution which contains a high amount of solute and a low amount of water. When the cell is placed in this solution the cell shrivels as the water movement is observed from the cell to outside down the concentration gradient like in option-3 and 5.
3. Hypotonic solution: The solution which contains the low amount of solute and high amount of water, when a cell is kept in the hypotonic solution the cell swell and could become flaccid if is a plant cell as in option 2, 4 and 6.
