The answer is <span>The foreign DNA is placed in a biological vector for cloning.
After target genes are identified and isolated, they are usually inserted into a transfer factor. In the process of creating genetically modified crops, the transfer factor is plasmid (a circular DNA molecule) from a soil bacterium Agrobacterium tumefaciens. Therefore, the transfer vector in which the foreign DNA is placed is a biological vector. It is not artificially produced but isolated from the living bacterium.

According to the research, risk assessment is a tool that helps us create cost-effective ways to protect our health and the environment.
<h3>What is risk assessment?</h3>
It is the process aimed at estimating the magnitude of the risks that could not be avoided, that is, it seeks to identify and eliminate risks present in the environment.
It allows you to adopt measures and make decisions focused on meeting the objectives established in terms of health and the environment.
Therefore, we can conclude that according to the research, risk assessment is a tool that helps us create cost-effective ways to protect our health and the environment.

Correct answer: D) From bacteria living in their roots
Nitrogen is an essential plant nutrients, but it is metabolically unavailable to higher plants and animals. It is available to some species of microorganism by biological nitrogen fixation in which nitrogen is converted to ammonia with the help of enzyme dinitrogenase.
The process of breaking apart the two atoms in a nitrogen molecule is called nitrogen fixation. Plant obtain the nitrogen they need from the soil which is already fixed by the bacteria and archae.
Example: <em>Azobacter</em><em>,</em> Nostac
