During the cell cycle, DNA replication occurs during the S phase or synthesis phase.

In this phase, the DNA is replicated and the cell makes a copy of its genetic material to prepare for cell division. Helicase is an enzyme that plays a critical role in the process of DNA replication by unwinding the double-stranded DNA. Helicase acts during the initiation stage of replication, where it helps to separate the two strands of the DNA double helix, creating a replication fork.

This allows other enzymes involved in DNA replication, such as DNA polymerase, to access the strands and begin synthesizing new DNA strands. Therefore, helicase performs its function during the S phase of the cell cycle.

Product production decreased when substance A was introduced to an enzyme process. More substrate was not added, but product formation was not increased. This leads us to the conclusion that substance A might act as an inhibitor.

Enzyme reactions are chemical reactions that occur as a result of enzyme catalysts. Enzymes are proteins that catalyze chemical reactions, speeding up chemical reactions in cells by up to a billion times.

The product is the outcome of the reaction. Enzyme reactions convert substrates into products. An enzyme-substrate complex is formed when the enzyme and substrate interact. The substrate is then converted to the product after the reaction is complete.

An inhibitor is a substance that slows down or prevents an enzyme-catalyzed reaction. The addition of substance A to the enzyme reaction caused a decrease in product formation, implying that substance A inhibited the reaction. The addition of more substrate did not increase product formation, implying that there was no enzyme activity. As a result, substance A may be an inhibitor of the enzyme's action.

Answer:

The depth of the ocean at that point is approximately 3,750 meters.

Explanation:

To calculate the depth of the ocean at a particular point using sonar, we need to know the time it takes for the sound wave to travel from the ship to the bottom of the ocean and back to the ship, as well as the speed of sound in water.

The speed of sound in water is approximately 1,500 meters per second (m/s).

If the sonar signal took 5 seconds to return to the ship, then the total time for the sound wave to travel from the ship to the bottom of the ocean and back to the ship is twice that, or 10 seconds.

We can use the formula:

Depth = (Speed of sound in water x Time) / 2

Plugging in the values we know, we get:

Depth = (1,500 m/s x 5 s) / 2

Depth = 7,500 meters / 2

Depth = 3,750 meters

Based on the given data, there is a clear relationship between the age of the rocks and their distance from the mid-ocean ridge.

The rocks closer to the mid-ocean ridge are younger than the rocks farther away from it. Specifically, the rocks that are 10 kilometers from the ridge are 300,000 years old, while the rocks that are 25 kilometers away are 1 million years old, and the rocks that are 40 kilometers away are 1,625,000 years old.

This pattern of younger rocks closer to the mid-ocean ridge and older rocks farther away is consistent with the theory of plate tectonics.

The rate of plate movement can be estimated by dividing the distance between two points on the sea floor by the difference in their ages. Based on the given data, the rate of plate movement between the 10-kilometer and 25-kilometer marks is (25 km - 10 km) / (1 million years - 300,000 years) = 15 km / 700,000 years ≈ 0.021 km/year. Similarly, the rate of plate movement between the 25-kilometer and 40-kilometer marks is (40 km - 25 km) / (1,625,000 years - 1 million years) = 15 km / 625,000 years ≈ 0.024 km/year.
