1. X axis - type of sound; y axis - sound level (decibels)
2. whisper - 20 decibels; normal talking - 60 decibels; rock concert - 120 decibels
3. Normal talking is 40 decibels more intense. You can figure this out by subtracting the decibels of whispering from the decibels of normal talking (60-20)
4. The pain threshold is 120 decibels. This means the jet sounds could be painful because it is 140 decibels, or higher than the threshold.

Answer:

1 -

x axis - types of sound

y axis - sound levels(decibels)  

2 -

whisper - 20 decibels

normal - 60 decibels

rock concert - 120 decibels

3 -

40 decibels more intense because a whisper is 20 decibels and normal talking is 60 decibels. So you take the two & subtract them 60 - 20 = 40. So that means it is 20 decibels more intense.

4 -

Pain threshold & a Jet plane

How are these two laws (law Dominance and Segregation) related
Kazeer [188]
This law explains that the pair of alleles segregate from each other during meiosis cell division (gamete formation) so that only one allele will be present in each gamete. ... Every organism inherits two alleles for each trait. The two alleles of a pair are different, i.e., one is dominant and one is recessive.

The light micrograph shows dividing cells near the tip of an onion root. Identify a cell in each of the following stages: propha
ad-work [718]

Mitotic division in onion root cells:

  1. Prophase: the emergence of chromatin threads that form chromosomes, the chromosomes are visible and overlap.
  2. Metaphase: chromosomes line up and line up in the middle of the equatorial plane. The centromere of the chromosome appears to have bonds with the kinetochores connected to the spindle threads.
  3. Anaphase: the centromere of the chromosome undergoes division then the chromosomes are pulled by the spindle threads towards the two opposite poles and leave the center of the equator that looks empty.
  4. Telophase: The cytoplasm divides into two identical-looking daughter cells. At the telophase stage, the process of cell division occurs in two parts and has identical properties.

Mitosis is a cell division through the stages of prophase, metaphase, anaphase, and telophase. The purpose of mitosis is for growth and regeneration which results in two daughter cells that are identical to the original parent cell. Mitosis occurs only once and lasts only during somatization.
