Answer:
This is called the macula lutea
Explanation:
Answer:
Sexual reproduction produces offspring which are distinct from the parent.This strategy is successful because this reproduction increases genetic variation, which entailsthe odds of some progeny, which are suited to new and challenging conditions.
Explanation:
Sexual reproduction produces genetic variability, as two nucleic unites to produce a new offspring this allows the fungus to adapt to new environments. Sexual reproduction in the fungi consists of three sequential stages plasmogamy, karyogamy, and meiosis.
It involves diploid chromosomes pulled into two daughter cells, each containing an haploid set of chromosome.
Plasmogamy is the fusion of two protoplasts which brings together two compatible haploid nuclei this nuclear types are present in the same cell, but are not yet fused. Karyogamy then leads to the fusion of the haploid nuclei and the formation of a diploid nucleus. The new cell formed by karyogamy is the zygote.
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.
The coral fossil would be a better estimate of past water depth. This is because most corals inhabit shallow water reefs, less than 150 feet deep. In contrast, pelagic fish may inhabit any open water (pelagic) part of the ocean, with depths ranging anywhere from a couple of hundred feet deep to miles in depth.
