1. In snapdragons, the color of the flower is controlled by incomplete dominance. The two alleles are red (R) and white (r). What is genotype of a pink snapdragon? Answer Choice Feedback A. or Incorrect. This snapdragon would be white. B. RR Incorrect. This snapdragon’s phenotype would be red. C. Rr Correct! Since the snapdragon is controlled by incomplete dominance, one allele for red (R), and one for white (W) would result in a pink flower. D. Rw Incorrect. This is not written correctly 2. If a pink-flowered plant is crossed with a white-flowered plant what is the probability of producing a pink-flowered plant? (Hint: Draw a Punnett square to help you answer the question) Answer Choice Feedback A. 25% Incorrect. The genotype for the pink flower is Rr and the genotype for the white flower is or. This would lead to a 50% chance of the offspring having a phenotype of pink. B. 50% Correct! The genotype for the pink flower is Rr and the genotype for the white flower is rr. This would lead to a 50% chance of the offspring having a phenotype of pink. C. 75% Incorrect. The genotype for the pink flower is Rr and the genotype for the white flower is or. This would lead to a 50% chance of the offspring having a phenotype of pink. D. 0% Incorrect. The genotype for the pink flower is Rr and the genotype for the white flower is or. This would lead to a 50% chance of the offspring having a phenotype of pink. 3. Bernadette is blood type O. She has two sisters. One sister has blood type A and the other has blood type B. Using this information and your knowledge of how blood type is determined, determine the genotypes of Bernadette’s parents for this trait. Answer Choice Feedback A. I Ani, IB I Correct! The genotype for type O blood (Bernadette’s type) is “ii”, so both parents must have at least on “i”. Since one sister is type B, one parent must have the IB allele. Since the other sister is type A, then one parent must have the IA allele. B. I A I A, IA I An Incorrect. This would result in children with only type A blood. C. I B me B, IB I B Incorrect. This would result in children with only type B blood D. I B I, IB I Incorrect. This would result in offspring with either type O blood or type B.
<span>In the perspective of cell theory it states that all life has cells:
1. Cells came from pre-existing cells
2. Cells are the basic unit of life
3. All life is composed of cell/s
More:
The
cellular organization relates with one another since the colossal cell,
the organ system is fundamentally composed of cells. Cells are the
building blocks of these structures and which creates such organ and
organ system. They associate as one cell intercommunicates with another
cell until all received the message and translates it and sends it with
another organ and to cell -vice-versa. And also, they become
interdependent with the other cell -other tissue -other organs -other
organ system. </span>c

Answer:
Options 1, 3 and 4.
Because most newly synthesized proteins fold correctly, the accumulation of misfolded proteins (or fragments) tends to occur slowly, thus explaining the slow onset of disease.
An amyloid fibril is stabilized by hydrophobic interactions between aromatic residues.
4) Soluble proteins that misfold and form amyloid fibrils become insoluble.
Explanation:
Amloid fibrils are peptide or proteins that are formed during invivo or invitro conditions. They ate formed when soluble proteins combine together to for insoluble fibres that are resistant to degradation. They are found in extracellular tissues and posses pathological effect. They accumulate after nerve cells and causes several illness.
