Answer:
The influenza virus has a negative sense RNA genome. In order to replicate, this means that the virus must first produce positive sense mRNA in order to produce necessary enzymes. Once the enzymes are translated, replication can take place. Positive sense cRNA is then made from the original negative sense RNA, using the enzymes. Negative sense RNA progeny are then made from the positive sense cRNA. The final viral progeny eventually bud from the host cell, ready to infect other cells.

Answer:
is concluded that while high temperature has an unfavourable effect on seed set of radish plants, it also weakens the incompatibility reaction between pollen and style, so that the result is a small increase in yield.
Answer: Option A
The three positions that nations occupy in the world system are core, periphery, and semi-periphery.
Explanation:

The core have high skill labor and high production cost compare to the others. The core countries dominate and use the periphery countries. The periphery countries also depend on the core countries for capital.
Answer:
According to the illustration of meiosis I, when sister chromatids stay together the phase to which it corresponds is telophase I (fourth option).
Explanation:
Meisois is a process of cell division whose final result is the obtention of two daughter cells with half of their genetic charge, with respect to the original cell. This process is divided into two parts, called meiosis I and II.
Telophase I corresponds to the phase of cell division in meiosis I, where the events that occur are the appearance of the nuclear membrane on the newly divided genetic material, cytokinesis -or cytoplasmic division- and above all due to the fact that each daughter cell already contains half of the genetic load, since the sister chromatids stay together.
