Answer: Option A) A-C-T-T-G
Explanation:
The base sequence on a strand of DNA is usually paired to specific complimentary bases. These specific pairings are as follows:
Adenine (A) pairs with Thymine (T)
Guanine (G) pairs with Cytosine (C). So when you find A replace with T, so also replace C with G and vice versa.
Thus, the complimentary sequence of the T-G-A-A-C DNA strand is A-C-T-T-G
According to the Big Bang theory, the universe was once very dense and is now expanding.
Tentacles of an octopus as well limbs of a lizard are analogous structures.
Analogous structures or organs perform the same function in different organisms that bear no resemblance to each other anatomically. Analogous structures are formed as a result of convergent evolution, i.e. different structures evolving for the similar function and thus having similarity. Tentacles of an octopus as well as limbs of a lizard are used for the similar function, i.e. locomotion in this case.
On the other hand, homologous structures result from divergent evolution. Homologous organs contain a similar basic structure but perform distinct functions in different organisms.

Answer:
Natural selection.
Explanation:
Natural selection is when organisms who are most adapted to their environment survive and pass on their genes while those with "unfit" genes die and don't get the chance to reproduce! This slowly creates a population that is most well suited to their habitat. Hope this helps again LOL! :)
