Answer:
<em>Agrobacterium</em> <em>tumefaciens</em> is a gram negative bacteria that is responsible for tumor formation in the different parts of plant body.
Explanation:
It causes crown-gall disease in plant body by transferring it's DNA into the plant body which include Ti plasmid.
There are 3 types of bacteria that form tumor in different plant ares.
<em>Agrobacterium rhizogenes</em>,<em> Agrobacterium tumefaciens</em> strains contain either Ti or Ri plasmid but <em>Agrobacterium vitis</em> contain only Ti plasmid which are virulent.
The transfer of T-DNA takes place into the body of host cells and then the DNA is expressed into the body of the host and thus forming gall or tumor.
As ice melts into water, kinetic energy is being added to the particles. This causes them to be 'excited' and they break the bonds that hold them together as a solid, resulting in a change of state: solid -liquid.

D- phosphorus</span>
<span>The idea of helping someone to get some help in return resulting to close interactions is a symbiotic relationship. In a symbiotic relationship, the two species in the relationship like bacteria and legumes live together.</span>
<span>Legumes have root nodules that provide a home for bacteria (rhizobia). Rhizobia that fixes nitrogen. They convert nitrogen gas from the atmosphere into ammonia. This ammonia is in turn used in the formation of amino acids and nucleotides in legumes. This is the nitrogen <span>cycle which involves a symbiotic relationship between bacteria and </span></span>
