Answer:
A. 0.035.
Explanation:
Female : cv-cSb+/cv-c+Sb
Male : cv-cSb/cv-cSb ( since test cross involves mating with a recessive parent )
Their progeny:
cv-cSb+/cv-cSb : parental
cv-c+Sb/cv-cSb : parental
cv-c+Sb+/cv-cSbc : recombinant
cv-cSb/cv-cSb : recombinant
Wild type phenotype (cv-c+Sb+/cv-cSbc) is a recombinant. Distance between the two genes is 7mu. Since map distance is equal to recombination percentage, there will be 7% recombinants in the progeny. Out of total 7% recombinants, 3.5% will be cv-c+Sb+/cv-cSbc( wild type) and rest 3.5% will be cv-cSb/cv-cSb (mutant type).
Hence, proportion of phenotypically wild-type individuals in the progeny of the test cross will be 3.5% or 0.035.
Answer: Correct respiratory dysfunction
Explanation:Laryngotracheobronchitis (croup) is a common upper airway infection. It blocks breathing because of the swelling of the larynx and trachea, and one of its primary symptoms is a "barking cough" that may be bad enough to cause gagging or vomiting. Children between 3months and 3 years are the most frequently affected, although it can occur in any age group.
This infection is viral and Parainfluenza is responsible for the majority of cases. Other causes include adenovirus, influenza virus A and B, RSV.
Symptoms first occurrence is usually suddenly at night and it's usually self limited, lasting about 3 - 5 days.
Symptoms may include;
Barking Cough
Fever
Drooling
Difficulty breathing
Hoarseness or Impaired voice
Sore throat
Phlegm
Corticosteroids (usually a single dose) is usually used to decrease inflammation and racemic epinephrine aerosols demonstrate the alpha-adrenergic effect of mucosal vaso-
constriction, helping to decrease edema. In the case of tachypnea, it could be a sign of trachea obstruction, so ineffective breathing pattern is checked for and a nebulizer treatment can be administered as it relaxes smooth muscles in the airway. Except in the case of severe restlessness which most likely arises from securing adequate oxygen and is an early sign of respiratory distress, so in this case, respiratory dysfunction is first corrected.

<span>Based on the description, i think the moth is exhibiting: A. Taxis behavior
Taxis is a movement made by organisms that carried out as a response to light. A moth naturally moved between the moonlight as a form of camouflage mechanism to avoid predators. But they often confused man-made light such as lamp as moonlight, which make them gather around it every time we turn on a light in dark time</span><span />
