The correct answer is A and C.
China's geographic location, with Gobi in the North, and to the West is Himalaya and seas to the east and south, which isolated early chinese civilization from other cultures.
C. China's civilization which is the oldest continuous civilization which i found in the world.
China civilization is the oldest written record in history. In the writings of shang they don't indicate any existence of the Xia.
When males place their sperm in the females' spermathecae, fruit flies can start laying eggs (a process known as induction). Induced egg laying has the selection benefit of ensuring that a male fly's sperm is utilized for fertilization, which is beneficial for male flies.
- The spermatheca is an ectodermal organ that only develops in Queens and is not present in workers.
- Spermathecae gets sperm from the male during mating.
- Because it assures that a male fly's sperm is used for fertilization, induced egg laying for male flies has this benefit.
Thus from the above points, we can conclude that egg laying in the fruit flies had an adantage.

Answer:
<em>The correct option is D) Y, X, Z</em>
Explanation:
The similarities in the amino acid sequence might predict that the organisms which share the most similar sequence are more closely related to one another.
As we can see the sequence Y, Q-Q-Q-N-N-S-C-C- is shares the most similarities with the given amino acid sequence of an enzyme from a worm, hence it is the most similar. The sequence X, -Q-R-Q-N-S-S-C-C-, shares more similarities with the amino acid sequence of the worm hence it is more closely related as compared to the sequence mentioned in option Z which is -Q-Q-R-N-S-N-C-C- .
