The translocon (commonly known as a translocator or translocation channel) is a complex of proteins associated with the translocation of polypeptides across membranes.[1] In eukaryotes the term translocon most commonly refers to the complex that transports nascent polypeptides with a targeting signal sequence into the interior (cisternal or lumenal) space of the endoplasmic reticulum (ER) from the cytosol. This translocation process requires the protein to cross a hydrophobic lipid bilayer. The same complex is also used to integrate nascent proteins into the membrane itself (membrane proteins). In prokaryotes, a similar protein complex transports polypeptides across the plasma membrane or integrates membrane proteins.[2] Bacterial pathogens can also assemble other translocons in their host membranes, allowing them to export virulence factors into their target cells.[3]

Answer:
1. symbiont
Explanation:
Symbionts are organisms interacting in a biological relationship that can be of the type mutualistic, commensalistic, or parasitic
In this case, there is a relationship of commensalism between two organisms: the human and the bacterium.
Commensalism is a relationship between two symbionts where one benefits and the other is not harmed or helped. Commensalism it is derived from the word commensal (old french), used for human social interaction. Sometimes the word commensal is used in biology, however, the term symbiont is used more frequently to refer biological relationships.
Answer:
C.organisms had adapted to new environments,givingrise to new species
Explanation:
-On his visit to the Galapagos Islands, Charles Darwin discovered several species of finches that varied from island to island, which helped him to develop his theory of natural selection.
-He noticed that each finch species had a different type of beak, depending on the food available on its island. The finches that ate large nuts had strong beaks for breaking the nuts open.

B. Mendeleev is the scientist who worked with decks of cards to develop the arrangement of elements on the periodic table
<u>Explanation:</u>
The scientist who worked with the deck of cards to develop the arrangement of elements on the periodic table is Mendeleev.
Mendeleev wrote the each element data on a card and arranged them in the order of the atomic weights. One more way is to group them with the cards of identical elements. After that he combined the two rules along with his cards of 63 elements that were found at that time, like increase in the atomic weight in each row as well as the elements of identical properties arranged in columns.
