They inhabit almost every natural habitat, from isolated tropical islands to forests.
The correct answer is d. 8p+; 9n; 10e−
Oxygen exists in three isotopes ¹⁶O, ¹⁷O and ¹⁸O. The atomic number of oxygen is 8. It means its nuclei has 8 protons. The given is oxide⁻² anion. This means it has gained 2 electrons. Thus, oxide anion have 8 protons and 10 (8+2) electrons. The number of neutrons depends on the isotope, in this question mass number is given¹⁷O. The mass number is the sum of the protons and neutrons in the nucleus. Hence, number of neutrons oxide anion will be 17-8 = 9 neutrons.

don't quote me on this but I'm pretty sure
Answer: C G A C C T A T G G G C... (and so on)
Explanation:
Think of this as one letter representing one half of a pair. The pairs are A and T, and C and G.
When you see a T, its opposite part of the pair is A, and vice versa. The same goes for C and G. To answer this, just write the opposite of what is there.
A -> T
T -> A
and,
C -> G
G -> C
Hope this helps!
The right answer is two generations.
5-Bromouracil has three tautomers that have different matching properties. The keto form is complementary to adenine, while one of the enol forms is complementary to guanine.
As a result, 5-bromouracil is likely to pair with both adenine and guanine depending on its tautomeric state at the time of replication, which introduces mutations as the replications. During the first replication the analogue will be incorporated in the DNA (in front of a T for example). At the second replication (second generation), the analogue will have a new base in front of it in function of its tautomic form (ie instead of having in front of a T it will have a C and a this moment the mutation becomes complete).
