Organisms that originated in a certain geographic region and can only be found in that region are said to be endemic.

Explanation:

Endemic organisms are taxonomic species (plants and animals) which originates and distributed only in specific geographic regions. This state of evolution is called endemism.

They are said to be native or indigenous to that particular region which can be an ecological habitat, an entire nation, an island, a mountain range etc. Certain parts are known for majority of their species being endemic like St. Helen Island, New Caledonia Island, Hawaiian Islands, Southern regions of Africa, and Australia.

The species becomes endemic to a particular region because of the presence of certain bio-geographical environmental qualities of that habitat which are favorable to that species.

When these conditions become unfavorable, then species becomes restricted leading to endangerment or extinction of the species.

Examples:

  1. Kangaroo - Australia
  2. Nilgiri Tahr, - Nilgiri Hills, India
  3. The Redwood trees of West Coast of the USA
  4. Plants like kalo, sumac of Hawaii

What is the difference between DNA, chromatin, and Chromosomes?
Serhud [2]
Deoxyribonucleic acid (DNA) is the hereditary material that lies within the nucleus of all cells in humans and other living organisms. Most of the DNA is placed within the nucleus and is called nuclear DNA.

A chromosome is made up of two chromatids which are joined by the centromere. The chromatids separate from each other during mitosis to form two new chromosomes. The DNA making up a chromosome is dispersed as chromatin.

Under a microscope, chromatids look like little dots and chromosomes are lines.

John Dalton proposed the theory of matter which is popularly known as the Dalton's atomic theory. In the atomic theory, Dalton identified from his experiments on gases that every matter is made up of small indivisible particles called atoms. These atoms are the smallest fractions of a matter.

  • All the atoms of an element are all alike.
  • Compounds form from atoms by simple whole number combinations alone.
  • Chemical combination of atoms involves the rearrangement of reactants.

Therefore, using these clues you should be able to answer the question.

astra-53 [7]

<u>Answer</u>:  

Different type of the same procedure that takes the place of the kidneys and cleans the blood are mutually all known as osmoregulation.

<u>Explanation</u>:  

Along with kidney there are other organs which helps the body to purify blood. These organs are lungs which exchanges carbon dioxide with oxygen and skin which helps in excreting the extra salt concentration from the body. In invertebrate animals the kidney is not present but osmoregulation takes place with the help of organelles and organs like vacuoles, nephridia, antennal glands, salt glands and malpighian tubules.
