Gravitropism is the answer
S phase is the DNA synthesis phase. During this portion of the cell cycle, the cell replicates its entire complement of DNA. It also forms the centrosome, which is the microtubule-organizing center that will eventually help the cell pull apart the DNA that will be divided between daughter cells.
The correct answer is C.
The egg sinks in freshwater because it is more dense than the water. So, to make the egg float, you would have to increase the density of the water. Since salt water has a greater density than freshwater, you would add salt to the freshwater, thus causing the egg to float rather than sink.
The primary concern of the scientist in clinical trial is patient safety.
A clinical trial is one of the final stages of any research process according to the requirement. Studies are done to find if the approach of the research and treatment is effective.
Clinical test or trial on human beings is done only after the pre-clinical phase which involves laboratory studies on animals (in vitro) to check the safety and efficiency of the drug. Animals are quite different from humans so human clinical trials are required to be done.
The main aim of clinical trial involves three major things to be considered: if the drug is working, the efficiency of the drug as compared to the currently present drug and most importantly that the drug is safe for human use and the patient is safe after the administration of the drug into the body.
Answer:
this is an extremely broad question. they do it through a problem, hypothesis, experiment, analysis, then conclusion.
