Pseudoscience is literally just FAKE SCIENCE. remember that
What a great way to see how bacteria exposed to Martian-like conditions will survive. By testing how well these bacteria do in the stratosphere we can gain insight into several things. 1) the likelihood that any bacteria still survives on Mars 2) how well bacteria introduced to Mars could survive and if there are existential risks to doing so and 3) how bacteria introduced to harsh conditions react more broadly, even on earth.
The correct option is D.
Endosymbiosis theory postulates that eukaryotic cells evolved from prokaryotic cells. Scientists have discovered that there are many similarities between prokaryotic cells and the organelles in eukaryotic cells.
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.
