Answer:
Mitosis creates diploid cells, while gametes (sperm and oocytes) are haploid cells
Explanation:
Mitosis is the process by which somatic (non-germ line) cells replicate, and two identical cells, called daughter cells are produced from each division. These cells are diploid, meaning that the cell has paired chromosomes. Meiosis is the process by which gametes, sperm cells and oocytes, are produced and these cells must be haploid, or contain unpaired chromosomes, so that when fertilization occurs, the chromosomes from the sperm cells and the chromosomes from the oocytes can recombine to create unique pairs of chromosomes for the resulting zygote. Thus, mitosis will never be able to create germ cells as germ cells must be haploid.
This is false.
These are called perennial plants. Annual plants go through their entire life process within a single year and stop existing, meaning they can't produce fruit every year.
Answer:
Las técnicas moleculares, especialmente aquellas basadas en la manipulación del material genético, permitieron automatizar el proceso de identificación y clasificación de especies
Explanation:
Las técnicas moleculares usadas para la clasificación de organismos son aquellas principalmente relacionadas a la manipulación de su material genético. En especial, las técnicas de extracción de ADN, amplificación mediante la reacción en cadena de la polimerasa (PCR) y posterior secuenciación han posibilitado automatizar el proceso de clasificación de organismos. Los marcadores moleculares de ADN basados en secuencias génicas evolutivamente conservadas tales como, por ejemplo, la secuencia del gen Citocromo Oxidasa I (COI) en animales, son ampliamente usados para automatizar este proceso de identificación y clasificación de nuevas especies.
I think the answer is "the older it is"
Reason: I might be wrong but is something (like a shell) gets buried in something (like sand), overtime many things (like dirt, soil, sand, etc.) will be on top of the original. This will make layers. So, the older rock is on the bottom since it has been there for the longest and it gets covered by other stuff (causing the layers).
Hope this helps! :) (If I'm wrong, sorry :( )
