B) Bacteria can be treated with antibiotics, viruses cannot.
C) Vaccinations provide immunity from viruses, but not bacteria.
D) Vaccinations provide immunity from bacteria, but not viruses.
Answer:
That is correct on USATestPrep
Explanation:
Bacteria can be treated with antibiotics, viruses cannot.
Antibiotics won't treat viral infections because they can't kill viruses. Viruses are not living and depend on a host cell to provide the machinery for reproduction.
B) Bacteria can be treated with antibiotics, viruses cannot.
Antibiotics have no target when dealing with viruses. Antibiotics work on bacteria because it targets the growth machinery in bacteria. Viruses are found inside a human cell and reproduce by inserting their DNA into a human cell. There are antivirals and vaccines out there for viruses. Our body’s immune system fights against viruses with antibodies!
B.0.35
C.0.42
The answer is; C
Use the Hardy Weinberg equiation for population in assumed equilibrium. ( p+q = 1)
If p = 0.3 then q=1-p = 1-0.3 = 0.7
People who are heterozygous for the disease are represented by 2pq = 2 * 0.3 * 0.7
0.42
A. There is no gene flow.
B. There are individuals moving in and out of a population.
C. The population is large.
XO D. There is gene flow.
X
Answer:
Under which condition would a mutation have the most impact on allele frequency?
There is gene flow
Explanation:
Mutation occur mostly during fertilization where there is gene flow and this makes it to have an impact on the allele frequency
Particles in warm temperature rise while the particles in cooler temperature sink:
Temperature is a calculation of the mean kinetic energy of a substance's atoms or molecules. Heat is the transition of energy from a material at higher to a material at lower temperature. When heat is provided, the particles in liquids and gases acquire kinetic energy, which increases vibration and start moving faster.
Thus as the particles travel farther apart, they take up more space, due to which particles in warm temperature rises, as it allows the liquid or gas to move upward. While cooler liquid or gas travel downward because no external energy is provided to them, thus on acquiring low temperature, the inter-molecular forces between particles increase which deduct spaces between them.
B. launch spy satellites into space
C. carry explosives
D. all of the above
