Only eukaryotes use mitosis, these cells have a single nucleus and membrane-bound organelles.
Answer:
A
Explanation:
The light energy from sunlight in photosynthesis is used to split the water molecule into H+ and O2-. The H+ is then used to reduce NADP+ to NADPH. Through photophosphorylation, the energy from the sun is also used to make ATP from ADP. As the electrons are passed from one protein to the other in the chain, the energy released is what is used to create ATP.
Oxygen is evolved out as a byproduct
NADP+ + 2e- + 2H+ --> NADPH + H+
Answer:
a
Explanation:
There are two major differences between mitosis and meiosis. First, meiosis involves not one, but Two cell divisions. Second, meiosis leads to the production of germ cells, which are cells that give rise to gametes. Germ cells are different from somatic cells in a critical way. Whereas somatic cells are diploid, meaning they have two copies of each chromosome, germ cells are haploid. The haploid nature of germ cells is vital to the process of sexual reproduction.
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.
Identical offspring, no formation of gametes, requires only one parent individual to reproduce
