The question is incomplete. The correct question is as following:
__________ studied the role of RNA in protein synthesis, specifically in the bacteria E. coli.
Answer:
Marshall Nirenberg and Heinrich Matthaei
Explanation:
Marshall Nirenberg and Heinrich Matthaei are two biochemist and geneticist who studied the functional importance of RNA in the process of translation (protein synthesis) experimentally in E.Coli.
Nirenberg and Matthaei discovered the first codon out of 64 codons present in RNA and they successfully performed translation (protein synthesis) in E.coli in a test tube. They decoded the first codon UUU (phenylalanine) by using synthetic RNA having only uracil nucleotides in a E.Coli and later they decoded further codons.
So, the correct answer is Marshall Nirenberg and Heinrich Matthaei.
Answer:
The root system is always adventitious. The stem is either underground or aerial. The leaves may be microphylls or megaphylls. Their other common characteristics include vascular plant apomorphies (e.g., vascular tissue) and land plant plesiomorphies (e.g., spore dispersal and the absence of seeds).

I believe it is a araebacteria
False. Continental slopes are fairly shallow and more of a gentle slope. Hope this helps!
Answer:
Alcohol fermentation
Explanation:
When oxygen availability is low, the cell can't perform aerobic respiration to breakdown glucose. Instead, anaerobic respiration must be performed. This occurs in cells which consume large amounts of energy, such as muscle cells. Anaerobic respiration produces much less energy than aerobic respiration
One type of anaerobic respiration formed by yeast is called alcohol fermentation (also called ethanol fermentation). This begins with glycolysis, where one molecule of glucose is broke down into 2 molecules of pyruvate. The energy from this reaction generates 2 molecules of ATP, and converts NAD+ to NADH.
Then, the two molecules of pyruvate are further broke down into 2 acetaldehydes (releasing two molecules of carbon dioxide as a by-product). These two molecules of acetaldehyde are then converted into tw molecules of ethanol, using the H ions from NADH, converting it back to NAD+. See the attached picture
This process is taken advantage of to brew beer and wine.
