Answer:
The North American Plate
Explanation:
Generally, earthquakes are located at the boundaries between plates where they collide, or grind past each other, or spread apart. New York City lies within the North American plate and the closest plate boundary is thousands of miles away in the middle of the Atlantic.
The effect of a catalyst is to increase the speed of the reaction, this is the speed at which reactants, A and B, are consumed, ant the product, C, is produced.
Given that when C is produced the solution bubbles, the bubbles are an indication of progression of the reaction.
The greater the speed of reaction, the earlier the reaction will end and the earlier the bubbles will stop.
So the student can identify the catalyst because the bubbles will stop first.
Answer: <span>The test tube that stops bubbling first contains the catalyst.</span>
A genetic outcome of a genetic cross between the same parents is independent of previous outcomes.
<h3>What is genetic variation?</h3>
Genetic variation can be defined as the genetic poll of an organism, which is the raw material trough which evolution can occur by natural selection.
During sexual reproduction, the formation of gametes generates different genetic backgrounds which are independent of distinct gametes.
In conclusion, each genetic outcome of a genetic cross between the same parents is independent of all previous outcomes.
