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.

The evidence of common ancestry is based on study of
three parameters; fossils record, homologies of various
organisms, and study of biogeography. Fossils record determines the similarity and differences of
bones as well as shells of different organisms over a given period of time. On the
other hand, studying of homologies involves assessment of mitochondrial DNA and
other proteins with an aim of finding similarity from one organism to
another. Finally, Biogeography is the
assessment of how continental drift might have separated organisms which had
got common ancestry and they were living together.
<h2>Behaviorism Approach in Psychology</h2>
Explanation:
- Behaviorism refers to a mental methodology that stresses logical and target strategies for examination. The methodology is just worried about recognizable upgrade reaction practices and expresses all practices are found out through cooperation with nature.
- One of the presumptions of behaviorist idea is that unrestrained choice is fanciful and that all conduct is dictated by a mix of powers contained hereditary variables and the earth either through affiliation or fortification.
- The behaviorist way of thinking ran simultaneously with the analysis development in brain research in the twentieth century. Its primary impacts were Ivan Pavlov, who explored traditional molding, John B. Watson (1878-1958) who dismissed thoughtful techniques and looked to confine brain science to test lab strategies. B.F. Skinner looked to give moral establishing to behaviorism, relating it to pragmatism.
