Answer AND Explanation:
Let B represent blue and R red flower.
B B
R RB RB
R RB RB
Therefore the first generation produced all purple flowers RB.
R B
R RR RB
R RR RB
In the second cross, the genotype ratio for RR: RB is 2:2
The phenotypic ratio is 2 red: 2 purple flower.
Answer:
All of the choices are correct
Explanation:
The respiratory syncytial virus (RSV) is an enveloped, negative-strand RNA virus (Paramyxoviridae family) capable of infecting ciliated cells of the airways by using its surface glycoproteins G and F for attachment and fusion during viral entry in target cells. RSV can affect the lungs and parts of the respiratory system (e.g., nasopharynx). Although RSV generally causes mild, cold-like symptoms, this virus may also lead to severe infection in babies (12 months) and infants, being one of the most common types of respiratory infections in children, older adults, and immunocompromised patients. Some common symptoms in individuals with RSV pneumonia include fever, nonproductive cough, dyspnea, wheezes, rales, rhonchi, etc.
