<h3>Living organisms </h3>
Living organisms; be it plants or animals are any organic or living system composed of cells and function as an individual entity.
- All living organisms share a number of key characteristics or functions such as movement, respiration, homeostasis, reproduction, growth, evolution, competition and others.
- Animals and plants also posess systems such as the digestive, skeletal, transport, nervous, excretory, respiratory and reproductive system.
- Living organisms are also taxonomically classified as either unicellular microorganisms or multicellular plants and animals

Answer:
The correct answer is- adaptive radiation
Explanation:
Adaptive radiation is the evolutionary process which allow the evolution of many species from a single species because some population of that species get into an environment which is different from their old environment in terms of food availability, predators, etc.
So the first bird that evolved the ability to fly branched into many different species due to habitat change is an example of adaptive radiation. The most famous example of adaptive radiation is Darwinian finches which evolved from an ancestral species of south America that reached Galapagos island.
It is true that uni-potent stem cells can only produce cells that are like themselves
Answer: Option B
<u>Explanation:</u>
Uni potent cell as their name suggests can only produce cells that are just like themselves. Compared to the other stem cells that undergo proliferation this produces a tissue of that particular type alone.
Though it can’t be of much use like other cells giving rise to different cell types this is confined to the generation of one particular tissue. The uni-potent cells help to renovate and recreate themselves too. Hence any damaged tissue can be replaced by the uni-potent cell giving rise to the same tissue in case of burns etc.
B. The processes needed for the cell to take in nutrients.
Hope this helps!
