Hace aproximadamente 250 millones de años ocurrió la extinción masiva del Pérmico-Triásico, un evento en el cual murieron hasta el 96 por ciento de las especies marinas y un porcentaje similar de las terrestres. Cerca de tres millones de años después se produjo la separación, a partir de un ancestro en común, de los linajes que con el tiempo darían origen a las aves y los cocodrilos. El grupo que incluye tanto a cocodrilos como aves se lo denomina Archosauria, que significa ‘reptiles dominantes’.

Answer: Golgi aparathus.
Explanation:
Golgi aparathus is an organelle that is found in eukaryotic cells. Soluble protein can enter Golgi aparathus in folded conformation because the golgi aparathus is a complex vessicles and folded membrane that help to package, transport and modify proteins and deliver them to the right location they will be needed.
If siRNA against a starch-branching enzyme was transmitted to humans, then it may affect the expression of glycogen-branching enzymes. RNAi inhibits gene expression.
Glycogen-branching enzymes are similar to starch-branching enzymes because glycogen bonds are similar to those observed between amylopectin.
The RNA interference (RNAi) pathway is an evolutionarily conserved mechanism used in molecular biology laboratories to inhibit the expression of target genes.
In the RNAi technique, a regulatory non-coding RNA called small interfering RNA (siRNA) that exhibits sequence complementary to the target gene sequence is used to inhibit and/or block the translation of the target mRNA (in this case, starch/glycogen-branching mRNA coding enzyme).

There are several precautions that should be taken during catastrophic weather. In the case of a hurricane warning two precautions you should take immediately are:
1. Fortifying your house: In doing this you give your home the utmost care and protection needed to give it the best chance to minimize damage.
2. Evacuate: This is more or less common sense. whenever there is a massive storm most evacuations are mandatory. Regardless whenever a storm is likely to hit your area it is best to pack up pets and all essentials and head for the safest area as quickly as possible. waiting till the last minute could get you stuck in traffic causing you to be caught in your car during the store which is more dangerous than remaining in your own house.
