Answer:
She should immediately rinse or flush her eyes with water.
Explanation:
One of the most important precautionary measure to be taken when working with explosive chemicals in the laboratory is the use of safety goggles. However, in this case, Maria claimed that she could not see through the safety goggles and wore them on top of her head rather than over her eyes.
Maria accidentally splashed some chemicals into her eyes while trying to pour it into a beaker. The primary or initial response to this happening is to immediately FLUSH OR RINSE her eyes with water. This will flush away the chemical from her eyes before it can have its detrimental effect.
Answer:
Propagación vegetativa
Explanation:
La propagación vegetativa es un tipo de reproducción asexual vegetal a partir de células, tejidos u órganos (por ejemplo, hojas, tallos y raíces) capaces de dar origen a organismos genéticamente idénticos mediante mitosis. Este mecanismo ha sido explotado en mejoramiento genético y en agronomía a fin de reproducir plantas con características fenotípicas deseadas a partir de un número reducido de células somáticas. Las regiones de la planta capaces de dar origen a un nuevo organismos se conocen como propágulos, los cuales pueden ser rizomas (a partir de raíces), tubérculos (tallos), estolones (brote laterales), etc. Diferentes tipos de suculentas tales como, por ejemplo, <em>Sedum morganianum</em>, Sedum<em> rubrotinctum</em>, <em>Kalanchoe daigremontiana</em> y <em>Graptosedum</em> o “California Sunset” se reproducen vegetativamente mediante propágulos foliares.
Explanation:
The Exon Junction Complex (EJC) is a eukaryotic molecular machine that interacts with spliced mRNA upstream of exon-exon junctions, providing a binding platform for other trans-acting proteins that determine the fate of the mRNA. The spliceosome deposits the ~335kD EJC in a non-sequence specific manner 20-24 nucleotides upstream of an exon-junction. Functionally, the EJC aids in nuclear export of spliced mRNAs, assists in nonsense-mediated decay of incorrectly spliced mRNAs containing premature stop codons, and enhances translation efficiency.
Pre-mRNA bound by a spliceosome is usually not exported from the nucleus, so as to make sure that only fully-processed mRNA travels to the cytoplasm to be translated. A protein called the mRNP exporter binds to the EJC, both through RNA interactions and interactions with the EJC-associated protein REF (RNA export factor) to help pre-mRNA exit the nuclear pore complex.
Interestingly, the efficiency of unspliced mRNA export is dependent on the length; longer mRNAs are exported more efficiently than shorter mRNAs. In spliced mRNAs, however, once the 5' exon is long enough to bind the EJC, the length of the spliced mRNA does not affect the export efficiency.
There are a certain number of EJCs in a cell, and they must be recycled in order to continue tagging mature mRNAs. Once in the cytoplasm, the ribosome-associated regulator protein (PYM) acts as a dissociation factor.
