Because the virus causes severe tissue necrosis and inflammation, secondary bacterial infections happen often during influenza outbreaks.
What are Secondary infections?
There are several ways that a primary infection can increase susceptibility to disease, leading to a secondary infection.
A secondary infection is one that develops during or following the treatment for a primary illness. It has been determined that a secondary bacterial infection affects up to 75% of people who acquire pneumonia after contracting the flu.
The prevalence of influenza and related secondary bacterial illnesses can be decreased by using infection prevention techniques. The best method to prevent this is to be vaccinated against the flu every year and practice proper hygiene, like frequent, thorough handwashing.

The polar head of a phospholipid is made of phosphate. The polar head has a negative charge that is made up of phosphate molecules. This polar region attracts water and is positioned outward to interact with the water.

The question is incomplete. The rest of the question is :
From these experiments, Mendel developed four hypotheses. They include all but ___________. A. One heritable factor may be dominant and mask the other factor. B. Any organism that "shows" a heritable factor must be homozygous. Eliminate C. An organism has two "heritable factors", now called genes, one from each parent. D. sperm or egg carries only one heritable factor for each trait in the offspring.
Answer:
<em>The hypothesis which is excluded is B 'Any organism that "shows" a heritable factor must be homozygous.'</em>
Explanation:
The hypothesis is wrong because even heterozygous traits are heritable.
The hypothesis mentioned in option B cannot be considered correct because Mendel's studies showed that all traits can be inherited from the parents. All factors whether dominant or recessive, homozygous or heterozygous are heritable characteristics. Mendel's study also confirmed that genes might carry homozygous or heterozygous alleles and these alleles independently assort into gametes and are heritable.
All other hypotheses are correct and their authenticity was validated after Mendel performed his experiments.
