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.

Answer: Mechanoreceptors
Explanation: These receptors perceive sensations such as pressure, vibrations, and texture.
Answer: e
Explanation:
I think it is e because if the father is normal than his X is healthy and so all his daughters who will get his X will be healthy as well because the illness is recessive. But the sons are going to take their mother X that is linked with this gene and they wont get their father’s X , which would have kept them normal.
This process is known as
translation
The process begins with messenger RNA (mRNA) giving instructions to amino acids. These instructions are sent with the help of transfer RNA (tRNA).
The amino acids form a chain called a polypeptide (proteins are made up of one or more polypeptide chains)
I have attached an image that will help your understanding of translation
I hope this helps! I'm happy to help with any other questions you might have :)

Answer:
Organism having the suitable traits appears more in the population.
Explanation:
Natural selection is a non-random process in the biological traits becomes less or more common in the population due to the different rate of survival of their bearer or their differential reproduction.
Natural selection leads to evolution because those organisms are selected to survive and reproduce which are having those traits that are better suited to a certain set of environmental conditions over others. As a result, the number of these organisms increases over time and they appear more in the population.
So natural selection leads to evolution as an organism having the suitable traits appears more in the population.
