Answer:
B) You measure the quantity of the appropriate pre-mRNA in various cell types and find they are all the same.
Explanation:
In the above scenario, we are using the control gene and we should know about the control gene is that its expression is either at transcription level or at translation level. For this situation we should examine the pre-mRNA stage of control gene in various cells because it is control gene so it should be present in various cells.
So, the best practice is to quantify the pre-mRNA level of gene then we can effectively solve the experimental problem and find the gene expression either it is at transcription or translation level.
Answer:
2. have no negative particle
Explanation:
Helium atoms contains 2 neutrons and 2 protons (or 2 electrons). Thus, it has a mass number of 4 and atomic number of 2.
Alpha particles are heavy and positively charged, which make them to be deflected in a magnetic or electric charge. So, the helium atoms used as alpha particles for the gold foil experiment must have no negative particle.
Answer:
Schooling
Explanation:
Schooling is a collective activity that is far more prevalent in bony fish than cartilaginous fish.
Schooling is a term used to describe collective activity in fish. For example, if a group of fish swims in the same direction in a coordinated fashion, they are schooling.
- Fish schools are one example of animal aggregation.
The correct answer is: [A]: "no double bonds" .

Answer:
A trio of antibiotics that had become powerless against MRSA decades ago proved effective in infected mice when used together.
Although more testing is needed, the results suggest that combinations of already-approved antibiotics might add to our options to combat MRSA infections.
