A prediction of the theory of Plate Tectonics is that new volcanoes can form at the boundary of two plates as magma seeps betwee

n them. To test this hypothesis, a scientist makes a map of existing volcanoes along a tectonic plate and measures the number of new volcanoes that appear over a decade. What would be the expected result of the experiment? How would you interpret the results if the scientist observes no new volcanic activity?

<span>Personally, I wouldn't expect any significant results. Maybe he'll get lucky and get a new volcano, but 10 years is virtually nothing on the geologic timescale. That's like trying to measure how many times a person blinks in 0.1 seconds. You shouldn't expect to see any.</span>

Answer:

For the map part drawing, the scientists will find that a very large number of volcanoes are situated close to the points of the meeting of the tectonic plates. The volcanoes not present at the edge of the plates now were possibly at the moment of their development and were moved away due to the movement of the plate. However, the scientist would not be able to find the new volcanoes as the development of a volcano is not something that occurs in a night.  

In case if the scientist does not witness new volcanic activity, it does not invalidate the theory as the period of observation is very brief. Ten years is not a substantial time period if seen geologically. The study would have to be performed for at least 1000 years to demonstrate some kind of result.

Which of the following situations would result in a t-test that not likely to be accurate? Choose all that apply
Mariana [72]

Answer:

The correct options are (c) and (d).

Explanation:

The assumptions made before using a <em>t</em>-distribution for a hypothesis test are:

  1. The scale of the data should be continuous or ordinal.
  2. The sample selected should be a simple random sample.
  3. The data selected should follow a normal distribution or form a bell-shaped curve when plotted.
  4. The sample selected must be large enough so that when plotted a normal distribution curve is formed.
  5. Homogeneous variance exists so that the standard deviations of the samples are approximately equal.

A sample size of 5 a sample size of 50 sample will not be accurate for a <em>t</em>-test because on of the sample size is, 5.

This sample size is very small and when plotted will not follow a normal distribution.

The sets that differed in variance will not be accurate for a <em>t</em>-test because for using a <em>t</em>-test homogeneity of variances is assumed.

Thus, the correct options are (c) and (d).

Scientists can use mutants to study metabolic pathways. These organisms have a mutation in a gene encoding a metabolic pathway e
riadik2000 [5.3K]

Answer:

The correct answer is - e. Phosphoglucose isomerase (phosphohexose isomerase or glucose-6-phosphate isomerase)

Explanation:

Phosphoglucose isomerase (phosphohexose isomerase or glucose-6-phosphate isomerase) is an enzyme that catalyzes the conversion of the glucose-6-phosphate to fructose-6-phosphate or fructose-6-phosphate to glucose-6-phosphate.

In the given question there most likely a mutation that takes place in Phosphoglucose isomerase as it is not able to convert glucose to fructose which is a growth defect.
