Answer:
The correct answer is - 4.34 days.
Explanation:
Given:
Distance from the sun to earth = 150 million kilometer
= 1500,00,000 km
The solar "wind" travels = 400 km/sec
= 400*60*60 km/ hour
= 1440000 km/hour
Then time = distance/speed
time = 1500,00,000 km/1440000 km/hour
time = 104.166666667 hours
time = 104.166666667/24
= 4.34 days.
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:
The process is called reabsorption.
The substances that are returned are glucose, amino acids, water and salt. Hope this helped
Nitrogen fixation, N2 --> NH3+, is not something that plants to by themselves but some plants have bacteria that does this. I believe that pea plants have these, but I'm not 100% sure.
Answer: Some of the intestinal symptoms elicited by pathogens such as salmonella, shigella, and Escherichia are due to the presence of lipopolysaccharides.
Pathogen associated molecular patterns binds to toll like receptors to elicit a response include lipopolysaccharide or LPS. The bacterial component interaction with the host involves LPS and other components of cell wall causing a septic shock. The triggering of any event of septic shock is directly related to the release of LPS or other bacterial toxins into circulation. Pathogen associated molecular patterns are the molecules which are made by the pathogen and needed for their survival or pathogenic character includes LPS.
