Answer:
One band of light density and one band of heavy density.
Explanation:
According to conservative model of replication, the original strands do not separate from each other during replication. Hence, after replication the old strands are together and the new strands are together.
Here, cells were grown in 14N medium first so 14N was used for DNA replication and all DNA molecules had 14N. When the cells were transferred to 15N medium, only 15N was available for replication process. New DNA molecules would be synthesised using 15N (15N15N) and old DNA molecules have 14N (14N14N). Hence, in density gradient one band will be of light density (14N14N) and one band will be of heavy density (15N15N).
Albert, a student researcher, varies the amount of food given to rats in an experiment to measure the effect on their learning behavior. In albert's study, the amount of food given is the independent variable.
An independent variable is under the control of the experimenter. Independent variable does not depend on the other variables involved in the experiment. Since the amount of food is varied, it is not depending on other variables like size of mice, weight, etc.
Answer:
Taxonomy
Explanation:
Taxonomy is basically the study and classification of organisms into families, genus, etc.
Hope this helped :)
When someone is lactose intolerant, it means its intestine cannot absorb lactose, which will stay in the lumen and be consumed by intestinal bacteria and produced gases, that's why intolerant lactose people have flatulence and abdominal pain while eating food with lactose in it.
Let's go back to the question, before being consumed, lactose in the lumen intestine will attract water from the enterocytes to its side by oncotic pressure.
Do not confound oncotic pressure (which concerns macromolecules like sugar or proteins) and osmotic pressure (which concern micromolecules like small ions (sodium potassium and chloride...)).
