A(n) _______ is an uncontrolled positive feedback loop between cytokines and leucocytes.
Vinvika [58]

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.

Imagine you are performing a cross involving seed color in garden pea plants. What F1 offspring would you expect if you cross tr
ehidna [41]

Answer:

B. 100 percent yellow seeds

Explanation:

When a gene has two alleles and one allele is dominant over the other, the dominant allele is expressed in the heterozygous state and the expression of the recessive allele is masked. According to the given information, the allele for yellow seed color is dominant over the allele for the green seed color.

Let's assume that the allele "Y" gives yellow color to the seeds while the allele "y" is responsible for green seed color. A cross between two pure breeding yellow seeded (YY) and green seeded (yy) plants would produce all the yellow seeded progeny with genotype "Yy".

YY (Yellow) x yy (green) = Yy (yellow)
