Separation of homologous chromosomes in meiosis I because it produces 2 haploid (n) daughter cells from a single diploid (2n) parent cell
Options for the question have not been given. They are as follows:
A) parasitism
B) mutualism
C) inhibition
D) facilitation
E) commensalism
Answer:
D) facilitation
Explanation:
In ecology, facilitation is used to describe community interaction between two species in which at least one of the species is benefited. One species "facilitates" survival of another species and hence the term facilitation. They can provide facilitation by providing them refuge from predation, competition, physical stress etc.
Facilitation is broadly of two types, mutualism and commensalism. In mutualism, both the interacting organisms are benefited. In commensalism, one organism is benefited and another one is neither benefited nor harmed.

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.
