Unlike a lytic infection, a lysogenic infection a. damages the host cell and causes it to burst b. requires a virus to inserts its nucleic acid into a host cell's dna. c. involves a virus and its nucleic acid. d. involves a host.

The correct answer is-  B) Requires a virus to insert its nucleic acid into a host cell's DNA.

Lytic and lysogenic cycle both are the two cycles/ modes of viral reproduction.

Lytic cycle includes five stages for the bacterial infection, which are attachment to bacteria, penetration of viral DNA, biosynthesis of viral DNA, assembly of viral particles that is maturation, and lysis ( virus performs lysis of the host cell and gets released from it).

Thus, lytic cycle damages the host and causes it to burst.

On the contrary, lysogenic cycle does not involve the destruction of the host. In this cycle, when viral genome enters host cell, it gets integrated or inserted into the host genome as prophage. It remains in an inactive form and as the bacterial chromosome is replicated, the DNA of virus is replicated along with it.

the corpus luteum secretes estrogens and progesterone. the latter hormone causes changes in the uterus that make it more suitable for implantation of the fertilized ovum and the nourishment of the embryo. if the egg is not fertilized, the corpus luteum becomes inactive after 10–14 days, and menstruation occurs.

i hope this : )
