Answer:
Parents: yellow, entire petals (CC FF) × white, fringed petals (cc ff) F1 (Cc Ff)
For the cross of a heterozygous F1 individual (Cc Ff) with a homozygous recessive
individual (cc ff) we would expect a phenotypic ratio of 1:1:1:1 for the different phenotypic classes.
Phenotype Observed (O) Expected (E) (O - E)2/ E or ( 2)
Yellow, entire 54 43.75 2.40
Yellow, fringed 58 43.75 4.64
White, entire 53 43.75 1.96
White, fringed 10 43.75 26.0
Total 175 175 35
Degrees of freedom = 4 - 1 = 3. The chi-square value is greater than 12.838 for a probability value less than .005, or 0.5% that random chance produced the observed ratio of California poppies.
B .t is unlikely that random variations produced the observed ratio.

Answer:
<em>The correct option is D) too few workers to support an aging population</em>
Explanation:
A positive population growth can be referred to as a situation when the population of a country is rising.
A negative growth population is referred to as a situation when the population of a country is becoming lesser. As a result of this negative population growth trend, there will be fewer workers to support the aged people. Also, there will be lesser people working for the economy of the country.
I believe the ratio of C to H to O in simple sugars or monosaccharides are 1 C : 2 H : 1 O or 1:2:1.
