Scientists make their hypothesis first, then they test it and collect the data
While all macromolecules are useful, protein is the only one produced by ribosomes. Ribosomes are the site of protein synthesis, and they convert the coded information in messenger RNA (mRNA) into an actual protein molecule. The mRNA molecule carries the message contained in your DNA to the ribosome.
Incorrectly. Because he has no idea wether the ants do it out of fear or other emotion (I dont think ants have the mental capacity to process emotion). He does'nt observe the ants are in fear he infers or guesses that they are.
The molecules will continue to move across the membrane in both directions

Answer:
Letter d. Evola virus could not produce an exotoxin
Explanation:
Viruses are acellular particles carrying genetic material only for their reproduction. None of the viruses produces toxins, viruses atack by altering the normal function of the host cell. In the other hand, bacteria involve in alimentary infections like <em>E. coli, S. aureus</em> and <em>C. botulinum</em> produce exotoxins to attack the host cells to colonize and start an infection. The exotoxin is too potent that alter the function of the intestinal cells before the immune system recognize the bacteria.
