Answer:
The correct answer will be option- synaptonemal complex.
Explanation:
The tetrad arrangement of the genetic material in an organism is mediated by a highly conserved structure known as the synaptonemal complex. The synaptonemal complex is formed during the prophase I of the meiosis I which attaches the chromatin of the homologous chromosomes.
The synaptonemal complex is a proteinaceous structure which is formed by the two lateral ladders like elements with a central portion composed of the central element. The chromatin gets attached to the lateral elements while the central a portion bridge space between the two ladders thus help in the formation of the tetrad.
Thus, option- synaptonemal complex is the correct answer.
Answer:
mutation, recombination, and immigration of genes.
Answer:
Explanation:Define dissection. The process of carefully separating tissues to reveal anatomical relationships.
Ok so answer for 5 would be
5) a mimicry could be a great fully helpful adaption because as an example, the butterfly’s that blend in with trees, or the butterfly’s that look like birds, can either scare away predators or they can blend in.
6) as an example, a blue tongue skink has a blue tongue which is very common in venomous animals. Whenever said skink is threatened, it puffs up, opens its mouth, and hisses. When most predators see the tongue, they assume it’s venomous/poisonous because of the bright color. Another example would be milk snakes who look like coral snakes to scare away predators
Answer:
La razón por la que a partir de los núcleos de las células del intestino de un renacuajo albino, se obtuvieron ranas albinas en lugar de células intenstinales, es que fué un experimento de clonación.
Explanation:
Este experimento realizado por John Gurdon en 1960, se conoce también como transferencia nuclear, y demostró que la información hereditaria guardada en el núcleo celular, es suficiente para generar un nuevo organismo y permanece integra durante el desarrollo de células diferenciadas debido a sus señales citoplásmicas.
