Answer:
1. 2 red: 2 purple
2. 2 red: 1 purple: 1 white
Explanation:
For this question, you need to create two separate punnett squares. The first punnett square would have C^R over one square with C^P in the square next to it, and on the other side would C^P next to one square and C^W next to the square below it. It doesn't matter what side you put the alleles on, just make sure the same alleles of the same flower are on the same side. Then, in order to find the phenotype, or in this case the color of the flowers' offspring, follow the dominance rules the question gave you. Remember, alleles don't have to be homozygous to determine what color they will be. Just make sure that the dominant allele is the allele used to determine the color. The same rules will apply for the second punnett square, and then you should get your answer. Hope this helps! :)

Just So you know, <span>The molecular clock, explains Blair Hedges, is a tool used to calculate the timing of evolutionary events. Instead of measuring seconds, minutes and hours, the molecular clock measures the number of changes.</span>
Answer:
The correct answer is C the polar head groups of phospholipid,glycolipid and cholesterol face towards the interior of the bilayer.
Explanation:
Plasma membrane contains various lipid molecules such as phospholipid,glycolipid,sphingolipid and cholesterol.The polar head groups of the phospholipid,glycolipid and cholesterol faces the hydrophilic region which is present outside the lipid bilayer and the nonpolar groups faces the hydrophobic region that is present interior of lipid bilayer.
Answer: The genotype for the parent organism whose genotype is unknown is Ff.
Explanation: Let (F) represent the allele for purple which is dominant over (f) and (f) represent the allele for white.
The parent organism whose genotype is unknown is heterozygous for purple colour (Ff).
A cross between Ff and ff will produce four offsprings: two of which are Ff (heterozygous for purple colour) and two are ff (white).
Ff x ff = Ff, Ff, ff and ff.
Since (F) is dominant over (f), (Ff) will manifest as purple while (ff) will manifest as white. Therefore, half of the offsprings are purple while the other half are white.
