Antibiotic used include kenamycin, ampicillin and tetracycline. This is useful to determine if and which bacteria took up the plasmid as they were supposed to during the process of recombination. Host bacteria are normally killed by these antibiotics. If the recombinant plasmids were taken up by the bacteria, plasmid may have contained a DNA gene for resisting the effects of one or more antibiotics. Host bacteria are placed in a growth medium containing an antibiotic to which they have a resistant gene in their recombinant plasmid DNA survivor. If they havent taken the plasmid they die.

The amygdala is thought to control defensive behavior via outputs from the central nucleus of the amygdala
What does the Amygdala do?
It is crucial in processing and regulating emotional reactions. Especially important in strong emotional reactions such as fear and anger
What does the amygdala control?
The amygdala is commonly thought to form the core of a neural system for processing fearful and threatening stimuli , including detection of threat and activation of appropriate fear-related behaviors in response to threatening or dangerous stimuli.
Central nucleus of Amygdala :
The central nucleus of the amygdala (CeA) has been traditionally viewed in fear conditioning to serve as an output neural center that transfers conditioned information formed in the basolateral amygdala to brain structures that generate emotional responses.
What does the central nucleus consist?
The central nucleus of the amygdala (CeA) is primarily composed of GABAergic interneurons which are finely controlled through glutamatergic neurotransmission and signaling. The CeA can be divided into the medial (CeM) and lateral (CeL) divisions

Soil erosion is a form of soil degradation and is referring to the displacement of the top layer of soil.Two human activities that can increase the rate of soil erosion are farming and logging. These two activities make the top layer of soil looser, resulting in the washing away of the soil by wind and water. Two natural events that can cause an increase in the rate of soil erosion are fire and earthquakes.
