Answer:
Ethylene. (Ans. D)
Explanation:
Ethylene controls the aging and ripening processes in plants. While many fruits and vegetables generate small amounts of ethylene, climacteric fruits like bananas produce larger quantities. This ethylene release accelerates respiration, triggers more ethylene production, and causes changes in color and flavor.
Therefore, when transporting green bananas over long distances to stores, the ethylene gas should be removed from their surrounding environment.
The response is the digestive system!
The urchin's body cavity is predominantly occupied by the digestive system.
Response:
The lysogenic replication cycle is a distinct procedure in the replication of the T7 virus.
Clarification:
The T7 virus targets bacteria (bacteriophage). Unlike viruses that infect plants and animals, it utilizes two cycles for replication within the host: the lysogenic cycle and the lytic cycle.
Virulent phages undergo the lytic cycle, leading to cell death through lysis.
The lysogenic cycle involves temperate bacteriophages, which can integrate with the host chromosome to form a prophage. This prophage replicates alongside the host cells' genetic material until it is prompted to switch to the lytic phase, producing new viruses that subsequently exit the cell through lysis.
This method of insertion into the host genome is termed lysogenic replication and is unique to bacteriophages.
Selecting the appropriate type of material for placement can help mitigate or ideally eliminate post-surgical tooth sensitivity. This choice can prevent the need for further endodontic procedures if the sensitivity continues. The application of resin-based amalgams remains a safe practice, involving a thin layer of resin that is allowed to set briefly before curing. <span>Clinical studies have shown that there is often a lack of proper use of curing lights. Ineffective curing light application can lead to an increase in complaints of postoperative tooth sensitivity.</span>
