Answer:
The given blank can be filled with cytokine storm.
Explanation:
Generally, influenza is self-restricting. Though serious cases can result in pneumonia and other issues, which can be deadly. However, such cases are very common in the elderly and in very young individuals. There are certain strains of the influenza virus, which are more dangerous to young adults in comparison to old or very young.
The strains, which influence young adults are considered to comprise a cytokine storm, that is, a positive feedback loop, which produces in between the production of cytokines and leukocytes. This cytokine storm generates an acute inflammatory reaction, which results in brisk accumulation of fluid in the lungs, resulting in pulmonary failure. The very young or very old are less vulnerable to this influence as their immune systems are less strong.
D. Low side pressure is high and high side pressure is low
Answer:
c. PP
Explanation:
Jake has dominant phenotype for polydactyly so he must be PP or Pp. Lucy has normal number of toes which is caused by recessive genotype so she is definitely pp.
If Jake was Pp, Pp X pp would produce half Pp and half pp kittens which means that some kittens should be born with recessive trait 18 toes. However none of the kittens have 18 toes and all of them have 21 to 25 toes. So Jake can not be Pp.
Jake is PP because when PP X pp all the kittens will have Pp genotype resulting in dominant phenotype of polydactyly. All the kittens have more than the recessive 18 toes hence they are Pp. However they have variable number of toes because polydactyly trait has variable expressivity.
