Answer:
tetracycline
Explanation:
When the DNA insert is ligated in Pstl site, the ampicillin gene is disrupted while <em>tetracycline gene is still intact</em>.
- If the bacterial colony is growth in a medium with only ampicillin, only the cells that contains the plasmid with the insert will grow.
- If the bacterial colony is growth in a medium with only tetracycline, the cells which have incorporated the plasmid will survive. We cannot distinguish between cells with plasmid + insert and plasmid alone.
- If the bacterial colony is growth in a plate with ampicillin + tetracyclin, only the cells with the plasmid without the insert will grow.
Therefore, to ensure that the cells of a bacterial colony contains the plasmid, they have to be seeded in a plate with tetracycline.
Answer:
If the air cools to its dew point temperature (in other words if it reaches saturation with respect to water vapor), condensation is forced and some of the water vapor in the air condenses into liquid water droplets.

desert, open ocean, lake, tropical rain forest
Explanation:
The net primary productivity tells us about how productive an ecosystem is. It is usually derived by the difference between the amount of carbon dioxide that producers used to the amount they release during their cellular respiration.
- The rainforest is the biome with the highest amount of net productivity.
- The amount of sunlight and organic matter used up during photosynthesis is very large.
- The tropical rain forest receives the highest amount of sunlight because the sun is overhead here.
- This provides energy to drive photosynthetic process in the presence of other available resources.
- Deserts are bare and lacks plants due to the extreme conditions here not favorable to life.
- The open ocean productivity is restricted to the photic zone where light is only able to reach
- Lakes are highly productive ecosystems.
