Hey there! Your answer would be:
The new technology allows detection of a structure that could not be detected previously.
I hope this helps!
Answer:
a) 0.1 mL
b) contamination
c) clumping of colonies
d) Uneven colonies
Explanation:
In general, when performing spread plates, 0.1 mL
mL of cell suspension is added to the plate to prevent the formation of a microbial contamination
Adding more than 1 mL of cell suspension to an agar plate will result in a clumping of colonies.
Adding less than 1 mL of cell suspension to an agar plate will result in a Uneven colonies
The
molecular clock tracks down nucleotide sequences for DNA or amino acids that
contain sequences of proteins. Scientists use this to deduce the time in
history where life forms possibly have diverged. This technique is also known
as a gene clock or an evolutionary clock.
