The correct answer is option D. She should place one flower in a similar container, but not pump carbon dioxide into it. She should also give each plant the same amount of water.
In the experiment, a control should be present to compare the effect of the variable in the experiment. In the control sample, all the parameters except the variable should be same as the experimental group. In this way, the comparison of the effect of variable can be easily done in an experiment.
In this case, the variable is amount of carbon dioxide the plant receives. So, Stella should include a control group by placing the plant in the same container and leave it on atmospheric carbon dioxide supply, no extra carbon dioxide should be pumped into it. Also, the amount of water she give to each plant should be the same to maintain the water level as constant.
Answer: thats a vagina my dude
Explanation:
Erosion is the transport of sediments. Agents of erosion include flowing water, waves, wind, ice, or gravity. Eroded material is eventually dropped somewhere else. This is called deposition.
Separate the soil from clay, sand, and silt. Then test each soil to find which is stronger or weak when it’s wet or dry.
Answer:
The pUC18 refers to a polylinker that is featured by enhanced multiple restriction locations. The enhanced number of restriction sites would upsurge the chance of the target DNA sequence being presented into the plasmid. If the sequence of the DNA is administered efficiently and obstructs the sequence of the LacZ gene in the restriction site, the bacteria will not be able to generate B galactosidase that cleaves X-gal.
When the X-gal in the medium does not get cleaved, the colonies become white. In case, if the DNA was not effectively presented into the host DNA and the LacZ gene can generate B galactosidase, X-gal will get cleaved and the colonies will be blue.
As the white colonies will be the hosts comprising the recombinant DNA, and pUC18 enhances the chance of DNA getting inserted, the white colonies will most probably comprise the recombinant pUC18.
