The organs of the male reproductive system are specialized for three primary functions: To produce, maintain, transport, and nourish sperm (the male reproductive cells), and protective fluid ( semen ). To discharge sperm within the female reproductive tract. To produce and secrete male sex hormones.
The answer is spicules. These
sharp-pointed structures are formed from calcium carbonate skeleton of
the organisms. They can also be formed from silica. They can be big (megascleres),
or microscopic (microscleres). Also dependent on the number of axis on the spicules, they are classified as monoaxon,
triaxon or polyaxon.
Answer:
<h2>Lytic cycle: involve that there is rupture( lysis) of the host cell and release many copies of virus.
</h2><h2>Lysogenic cycle: involve the insertion of the nucleic acid of a bacteriophage into host genome, known as prophage.
</h2>
Explanation:
There are many similarities and differences between lysogenic and lytic cycles that;
1. Lysogenic cycle of bacteriophage :
i) in lysogenic cycle: bacteriophage insert its DNA with that of a host, known as prophage and it replicates with host.
2. Lytic cycle of bacteriophage:
i) lytic cycle is that it results in many copies of the virus very quickly and the cell is ruptured and many copies of virus are released.
4. Similarity is that in both cycles bacteriophase inter into the host and use their machinery.
Mainly because it was extremely hot at the beginning of Earth's time.
