Answer:
The flu virus changes every year.
Explanation:
The virus that causes the flu mutates rapidly. Each year, a different flu strain causes the flu, which explains why you need to get a new flu shot every year. The antibodies you produced in response to last year's flu shot won't protect you from this year's flu. It is difficult to keep up with a quickly evolving virus like the influenza virus.
Doctors recommend annual flu shots to deal with the constant evolution and mutation of flu viruses. The rapid mutation rate of the flu virus requires the development of new vaccines each year to combat emerging strains. This process allows the flu shots to help control and mitigate flu outbreaks.
Doctors recommend getting flu shots each year due to the constant evolution and mutation of influenza viruses. Each year, scientists across the globe try to predict the flu strains that will be the most widespread and harmful. This prediction is based on how flu strains have evolved over time and over the past few flu seasons.
Several viruses, such as the flu, mutate and replicate at a rapid pace. The vaccine developed to protect against last year's flu strain may not offer protection against the coming year's strain due to the virus's evolution and adaptation.
The high rate of mutation in flu viruses makes it particularly difficult for the immune system to recognize different strains. Although the body may develop immunity to one strain through natural exposure or vaccination, new strains keep emerging that the immune system won't recognize.
The virus's surface molecules mutate, causing the flu to alter sufficiently each year such that the previous year's vaccine may not protect against the coming year's common flu. Therefore, new vaccine formulations need to be derived for each flu season.
Every year, new flu vaccines are developed to be effective against the expected dominant strains. These strains are typically cultivated in eggs and used to produce either an inactivated or a live attenuated vaccine. Through this process, annual flu shots aid in controlling influenza outbreaks.

From the example given, Cardiovascular diseases are not caused by poor lifestyle choices.
Answer:
False
Explanation:
Some cardiovascular diseases are congenital.
b. spine stretch
c. calf stretch
d. hamstring stretch
Spine stretch is not a very efficient exercise for the lower body because it can cause a slip disc problem.
Further Explanation:
Stretching is an effective physical activity that improves the flexibility of an individual. It is an angle at which a specific muscle is relaxed and contract. Three different types of stretching are there,
Stretching improves the blood circulation, coordination, and flexibility of the body. Sometimes it can waste time because over-stretching affects the spine adversely. It can worsen the back problems of an individual that leads to a slipped disc. Stretching your back might feel good for some time, but it’s not good for the spine. Muscles are not the problem. More range of motion associates to more low back pain.Stretch positions are the same that can cause disc herniation. Also, spine stretchcan cause pain for a prolonged time and affect and individual in the future.

The truth about genetics and environment is that scientists agree that both genetics and environment are important in developing self-esteem, as indicated by option C, because both factors are important in a person's development.
Genetics influences inherited traits such as physical characteristics, disease risk, and behavioral tendencies; therefore, genetics and environment both play important roles in shaping a person. The environment, on the other hand, includes everything that surrounds a person, such as their upbringing, education, social interactions, and experiences that shape their perspective.
As a result, scientists agree that both genetics and environment are important in developing self-esteem, which is Option C, because both factors are important in a person's development.

Answer:
C
Explanation:
"Scientists agree that both genetics and environment are important in developing self-esteem".
This is a TRUE statment.
Answer:
fixed-ratio; variable-ratio
Explanation:
The fixed ratio is a reinforcement method. Reinforcement is given in this method after a number of responses have been completed.
The number of responses expected continues to be constant.
A variable-ratio schedule is a reinforcement schedule where an unknown number of responses reinforce the response. This routine produces a reliable, high response rate.
Betting and casino activities are great examples of a payout dependent on a schedule for a variable ratio.
