Activity 2: Observing Seedlings
Compare the seedlings in your P, and P₂ plates. Record the color differences you observe between the P,
and P₂ seedlings. Remember that these are the phenotypes.
P, seedling color
P₂ seedling color.
F, seedling color
Compare the parental seedlings to the F, seedlings.
Which color is produced by the action of a dominant allele?.
Remember that each color is caused by the action of an allele of a color gene. As a class, decide on the
allele symbols you will use and record them here.

Germination can not be observed here, but if it is a monogenic trait controlled by complete dominance, then the genotype can be homo-zygous (e.g., AA) or heterozygous (e.g., Aa).
What is a dominant trait?In genetics, dominance refers to the phenomenon where one allele completely masks the expression of another allele (the recessive allele) in heterozygous individuals.
In this case, the genetic cross might be Parental 1 (AA) x Parental 2 (Aa) >> Filial 1 F1 1/2 AA + 1/2 Aa.
In conclusion, germination can not be observed here, but if it is a monogenic trait controlled by complete dominance, then the genotype can be homo-zygous (e.g., AA) or heterozygous (e.g., Aa).

Suppose a soprano's range extends from A below middle C (frequency 220 Hz) up to E-flat above high C (frequency 1244 Hz ). Although the vocal tract is quite complicated, we can model it as a resoNting air column, like an organ pipe, that is open at the top and closed at the bottom. The column extends from the mouth down to the diaphragm in the chest cavity, and we can also assume that the lowest note is the fundamental. How long is this column of air if v=354 m/s ?

This is measures by open harmonics frequency.
f= n*V/(4*1)
What is frequency?
Frequency refers to the number of waves that pass a fixed point in unit time. Frequency is denoted by the symbol f, and is measured in hertz (Hz).
Given,
f=220
velocity= 354 m/s
=> 220 = (nl)*(354)/(4*1)
=>1244 = (n2)*(354)/(4*1)
=> n2/n1= 5.65
=> n1=1, n2=6
=> = 40 cm (final answer).

discuss briefly on the origin of life according to creationists and naturalists
Answers
Answer:
Creationists believe that a god created everything in the universe, including all life. Typically they don't believe in evolution; they believe that their deity created every species exactly how it's supposed to be and they don't need to change. They believe that everything in nature happens for a planned reason.
Naturalists believe that everything in the universe happens by chance. They believe in theories like the Big Bang Theory, which states that the universe itself was created by chance. They also believe in evolution - that every species adapts to its surroundings and evolves more desirable traits. Naturalists believe that the first life happened due to the correct conditions coming together by chance to create unicellular organisms, which eventually reproduced, mutated, and evolved into the millions of specialized species that exist on earth now.
