Answer:
What causes ocean waves? Ocean waves are created by the transfer of energy from the atmosphere to water. Most water waves are generated by wind moving over the water's surface that creates fractional drag. ... The water molecules within deep water trace a series of circles that extend below the surface of the wave base
Explanation:
The correct answer is: C) exposing the bacteria to an antibiotic that kills cells lacking the resistant plasmid
The plasmids are inserted into bacteria by the process called transformation. Bacteria need to be treated, for example with heat, in order to take up foreign DNA (recombinant plasmid). A inserted recombinant plasmid contains an antibiotic resistance gene, which allows bacteria to survive in the presence of a specific antibiotic. So, this fact is used for the selection of bacteria that are and are not transformed.
Answer:
C) 64% AA, 32% Aa, 4% aa
Explanation:
The frequency of dominant allele A is = 80% = 0.8
Since the population is in Hardy-Weinberg equilibrium, p+ q = 1
Here, p= frequency of dominant allele
q = frequency of recessive allele
Given, p= 0.8
So, q = 1-p = 1-0.8= 0.2
Frequency of genotype AA = p2 = 0.8 x 0.8 = 0.64 = 64%
Frequency of genotype aa = q2 = 0.2 x 0.2 = 0.04 = 4%
Frequency of genotype Aa = 2pq = 2 x 0.8 x 0.2 = 0.32 = 32%
Answer:
Mycoplasma genitalium
