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.
that it was a weak enough disease to use the anibiotic to kill it off if it were cancer they would have to use cemo therapy witch is EXTREMLY harmful to the pasient thats how my dad died so i know
i hope this helps have a wonderful day
Answer:
An allergic reaction
Explanation:
An allergic reaction occurs when our immune system misinterprets a harmless substance into a harmful antigen and initiate an over-expressed immune response against it. Some of these allergic substances are pollen, molds, insect stings, etc.
These allergens trigger the production of IgE antibodies in the body which interact with different cell and initiate the release of chemicals like histamine that cause symptoms of allergic reaction.
It can affect the nose, skin, lung, stomach lining, etc. Therefore the correct answer is an allergic reaction.
Answer:
Dewy Grass. Dew is a natural form of water, formed as water vapor condenses. ... This forces water vapor in the air around cooling objects to condense. When condensation happens, small water droplets form—dew.
so it's C
Explanation:
Answer:
The correct option is Number 1. AaBb x AaBb
Explanation:
Genes can be described as basic hereditary units. The genes are made up of DNA.
A gene carries two alleles for a particular trait. These alleles are present at the same loci in the homologous chromosomes. If the two alleles are similar then they are termed as homozygous e.g AA, BB. If the alleles for a trait are different then they are termed as heterozygous e.g Aa and Bb.
