Didn't you say that the water at 39 degrees is more dense than water at its freezing point? I think the reason organisms would die is because the water already starting to structure in a crystal form, when it starts to freeze into ice. This probably why it kills the organisms, is because the water ceases to allow the organism to function at those temperatures.

Assume that the mutation rate for a given gene is 1 × 10−6 mutations per generation. For that gene, how many mutations would be
sertanlavr [38]

Answer:

500

Explanation:

Mutation rate is largely known as changes that occur in the frequency of a particular gene over an extended period of time

So given that;

the  mutation rate of a particular gene = 1 × 10⁻⁶

The expected mutations after 500 million sperm are examined will be:

= (1 × 10⁻⁶)×(500,000,000)

= 500

Thus, The expected mutations  = 500

Based on the temperature data in the table which chemical reaction should the students use for their food carrier design
Sladkaya [172]

Answer:

Reaction 1

Explanation:

Reaction 1 would be the most suitable in this case. This is so because in reference to the question you are wanting to keep the food warm over long periods. So in reference to the data in the chart reaction 1 continues to heat up over long periods of time. However, with the other reactions (2, 3, 4) temperatures vary and some even decrease constantly. Therefore showing that the other reactions are invalid to help reach your goal referencing back to the question.

Question 22 (Essay Worth 3 points) (02.01 HC) A prediction of the theory of Plate Tectonics is that new volcanoes can form at th
Darina [25.2K]

Answer:

What would be the expected result of the experiment?

For the drawing of the map part, the scientific will find that effectively, a very large number of volcanoes are located near the meeting points of tectonic plates. The volcanoes that aren't now at the edge of the plate were most probably at the moment of their formation, and were moved away by the movement of the plate.

But I doubt the scientist would be able to identify many new volcanoes, because the creation of a volcano isn't something happening overnight.

How would you interpret the results if the scientist observes no new volcanic activity?

I would say that does NOT invalidate the theory because the observation period is extremely short.  10 years is an insignificant amount of time geologically speaking... the study would have to be conducted over at least 1,000 years to maybe have some results at all.   Just imagine how many volcanoes there would be if a new one was created every 10 years along the side of a tectonic plate.
