Answer:
No organisms
Explanation:
This is because the kind of symbiotic relationship between plants root and microbes is mutualism. In this relationship both organism s benefit and non is harmed. The microbes make nutrients available for the root, it increase root permeability and also root metabolism while the roots provide home for the microbes and Al's derives food.
Answer: B. great impact when humans use alternative water sources for non drinking functions.
Great impact when humans use alternative water sources for non drinking functions is the correct option because use of alternative water sources can deplete the overall available water for the present as well as for the future generation of the human population. This is against the concept of sustainable development which suggests that natural resources should be used in such a way so that these can meet the needs of the present population as well as that of future generation.

Answer is A. A Hox gene
Hox genes are a series of genes that controls the differentiation of cells and tissues in an embryo by turn on and off other genes. If Hox genes express incorrectly, a major changes in the morphology of the individual can be seen.
Let’s understand this with an example: The Ultrabithorax, a Hox gene determines the Third thoracic segment in <em>Drosophila melanogaster</em>. Third thoracic segment displays a pair of legs and a pair of reduced wings used for balancing. In the mutant<em> Drosophila</em> the functional Ultrabithorax protein is absent. Due to this mutation, the third thoracic segment now expresses the same structures found on the second thoracic segment, which contains a pair of legs and a pair of wings which are fully developed .
The one that can adapt quickly. Survival of the fittest is a common statement about this.
