Answer:
The question lacks options and the incomplete punnet square; the incomplete punnet square has been added as an attachment while these are the options:
A) All red flowers
B) All pink flowers
C) 1 red : 3 pink flowers
D) 3 red : 1 pink flowers
The answer is D
Explanation:
According to the question, the genotype of a plant that produces red flower phenotype is about to be determined. For this flower colour gene, two alleles are involved in which the red color (R) allele is dominant over the pink color (r) allele I.e. the R allele will mask the expression of r allele in a heterozygous state.
The red-flowered plant with unknown genotype was crossed with a heterozygous red-flowered plant (Rr). Since a red flowered plant can either be Rr (heterozygous) or RR (homozygous), we use the Rr plant in the punnet square. The unknown genotype, assuming it has a Rr genotype, will produce RR, Rr, Rr and rr offsprings when crossed with another heterozygote (Rr).
These offsprings show a 3 red : 1 pink phenotypic ratio, making option D a valid prediction.
R r
R RR Rr
r Rr rr
Genetic material is being duplicated during C. Interphase of the cell cycle.
Answer: The article is a emotionally charged tone ( argumentative tone). A argumentative article is based on a persons opinion and is driven by their thoughts. this is shown through when the author wrote, "NASA’s space program is worth preserving at any cost." This shows that the author personally believes that the space station needs to be preserved, therefore their tone is argumentative since they are trying to prove their opinion to be right. This is also presented when the author stated "All of these activities offer hope to our increasingly overcrowded planet." and "It is impossible to list all the benefits of a thriving space program." All of these examples show that the author has taken a strong opinion on the matter. This therefore makes their town argumentive and emotionally based.
