Explanation
Conjugation is the transfer of DNA between bacteria through a pilus, a narrow tube-like structure. This process allows for the exchange of genetic material, such as plasmids, between bacteria. It plays a crucial role in bacterial evolution and the spread of antibiotic resistance genes. Operation, transduction, and transformation are not accurate terms for this specific process.

Explanation
After the hurricane, uprooted trees were laying over the ground. This is the correct answer because "laying" is the correct past participle form of the verb "to lay," which means to put something down in a reclining position. In this sentence, the uprooted trees are being described as lying or reclining on the ground. The past tense form "were" is used because the sentence is in the past tense.

Explanation
The equation given is y(x-1) = z. To find the value of x, we need to isolate it on one side of the equation. By dividing both sides of the equation by y, we get (x-1) = z/y. Adding 1 to both sides, we get x = z/y + 1. Therefore, the correct answer is z/y + 1.

Explanation
The US has a constitutional federal republic government. This means that power is divided between a central government and individual states, with a written constitution that outlines the rights and responsibilities of the government and its citizens. The government operates under a system of checks and balances, with elected representatives making decisions on behalf of the people. This type of government allows for democratic processes, protection of individual rights, and a balance of power between different branches of government.

Explanation
Supreme Court justices are appointed and not elected by US citizens. The President of the United States nominates individuals for the position of Supreme Court justice, and they are then confirmed by the Senate. This process allows for an independent judiciary, separate from the political sphere. Unlike the President, senators, and governors who are elected by the citizens, Supreme Court justices are chosen based on their qualifications and expertise in law rather than through a direct electoral process.

Explanation
Stomata are small openings found on the surface of leaves and stems of plants. They are responsible for gas exchange, allowing the plant to take in carbon dioxide for photosynthesis and release oxygen and water vapor. Xylem and phloem are vascular tissues responsible for transporting water and nutrients throughout the plant. The cuticle is a waxy layer that covers the surface of leaves and helps reduce water loss, but it does not directly participate in gas exchange. Therefore, stomata is the correct answer as it is specifically designed for gas exchange in plants.

Explanation
