Answer:
Las teorías extraterrestres o de panspermia sugieren que la vida existió en el espacio exterior y fue transportada por meteoritos, asteroides o cometas a una Tierra receptiva. En este caso, el origen de la vida no está relacionado con los posibles entornos de la Tierra primitiva.
Explanation:
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.
Cold ocean water flows from the north pole towards south and affects the climate locations near the Atlantic Ocean.
Answer:
C. Four Haploid Sperm Cells
Explanation:
Meiosis is a cell division measure that creates four haploid cells (gametes) from a solitary diploid germline cell. In males, meiosis is essential for spermatogenesis, the cycle to produce sperm. Sperm are the haploid cells that are produced in meiosis.
Meiosis is a profoundly moderated cell division measure in eukaryotes that produces 4 cells (gametes) from a solitary cell (mother). Nonetheless, Nondisjunction in the male of Drosophila causes much of the time sperm with an addition or loss of chromosomes.
Eukaryotes contain linear chromosomes and therefore require telomerase to prevent loss of the ends of the chromosomes
