Answer:
1. Decibels
2. whisper - 20-decibels, normal talking - 60 decibels, rock concert - 120 decibels
3. 10,000
4. A Jet plane
Explanation:
1. The unit refers to what specifically is being measured. If the graph was of heights, it could be metres, centimetres, feet, or inches, for example. In this case, the graph is of sound level. We can see beside the Y axis label "Sound Level" that the unit is decibels.
2. Take each individual sound source and look at how tall the bars are (purple rectangles). For each one, we can look across to the Y axis (left side) and see the corresponding sound level for each
3. We were told in the introduction to the question that for every 10 decibel increase, the sound increases by 10 times. So going from 10 -> 20 decibels represents a 10x increase, and 10-> 30 represents a 100x increase.
To figure out the increase from whisper (20) to normal talking (60), take away 20 from 60 to see how many decibels difference there are between the two levels.
60-20 = 40
There is a 40 decibel increase. If 10 decibel difference = 10x and 20 decibel difference = 100x, then 30 = 1000x, and 40 = 10,000x (keep adding a 0 with every 10!)
4. We can see from the graph that the pain threshold is 120 decibels. The sound level that is greater than the pain threshold (meaning it would be painful) is the jet plane.
Answer:
A formation of a volcano
Explanation:
A natural event that can occur either over a few weeks or over a few million years is <u>a formation of a volcano</u>. Volcanoes are accumulated when magma from inside the Earth's uppermost mantle acts its approach to the surface. Near the covering, that explodes to form lava flows as well as ash sediments. Extra time as the volcano remains to emit, it will become more prominent.

Answer:
Let's assume curly hair is the dominant trait and trait hair is the recessive trait.
Therefore, our cross is AA x aa. Drawing a Punnett square will then give us all heterozygous individuals.
