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.

The components of the second line of defense against microbes may be characterized as responders to invasion. It is a non specific resistance that destroys invaders in a generalized way without targeting specific individual cells; For example, phagocytic cells ingest and destroy all microbes that pass into body tissues. The first line of defense on the other hand,includes intact skin, mucous membranes, sebum, tear, among others.
Answer:
Because each strand acts as a template for the synthesis of a new, complementary strand.
Explanation:
This is known as semiconservative DNA replication. Leading and lagging strands are complementary, antiparallel strands (one is 3'-5' while other is 5'-3- direction) which are replicated differently. The leading strand is replicated continuously while the lagging strand is replicated in fragments-Okazaki fragments. Replication of both strands is performed by DNA polymerase.
