C because it is right in the middle of the spectrum, so it is neither lowest wavelength or highest energy. “Visible” indicates that we can see it, so C is the only answer that makes sense
Answer:
They can be preserved over geologic time inside pebbles of amber.
Explanation:
Answer:
There is no specific test available for a perticular or any individual bacterium to be identified. A prticular test can only narrow down the choices on the basis of characteristic each test excludes or includes.
Most of the time, to identify a particular bacterium atleast 3 to 4 tests are required. Each test can give postive result to be positive for a new group of bacteria.
Answer:
Substitution Mutation
Explanation:
It can’t be deletion or addition as the base pairs of DNA haven’t shifted to the right or left.
If they had the second sequence would have an extra/one less base pair which isn’t the case.
It can’t be an inversion, as that’s where the base pairs from the opposite DNA strands are inverted/switched.
If it was inversion, you would have had a C instead of an A for Sample 2.
This is due to complementary base pairing where guanine bind with cytosine and adenine binds with thymine.
Therefore, this only leaves substitution as a viable answer.
