We will attempt to introduce a gene responsible for the resistance to the antibiotic ampicillin.
Bacterial transformation is a molecular technique widely used in genetic engineering. Its basis involves the introduction of a foreign DNA into a host organism. This will result in the expression of a foreign gene by the host bacterium. In this example, our host organism is a bacterium who is sensitive to the antibiotic ampicillin. By introducing a gene for resistance to this antibiotic, the bacterium will become ampicillin resistant.
I think the correct answer would be e.coli
Speed of sound in water = 1500 m/s
frequency = 20Hz
wavelength = s/f = 1500/20 = 75m
The two kinds of unbalanced forces are:
- Net Force: Is the vector sum of all forces acting (pushing or pulling) on an object.
- Resultant Force: is a force that alone produces the same acceleration as all those forces.
To effects that unbalanced forces have on objects are:
- Can make an object move or stop.
- Can speed up or slow down an object.
Here are some examples:
- When falling out of a plane when sky diving, this is making you move faster. Then when you are using a parachute, you are slowing down.
- A man uses force to roll down an object from the top of a hill.
Species diversity hurts ecological succession. Explanation: Species diversity does not contribute for ecological succession. The diversity among the species is high at pioneer community. However as time passed competition and interaction causes a significant drop in species diversity.
