Nonsteroid hormones, which include proteins, peptides, and amines, exert their effects by binding with specific receptor molecules on the target cell membrane. Each receptor molecule has a blinding site, to which the hormone binds, and an activity site, which interacts with membrane proteins. The binding of hormones and membrane proteins to the receptor alter the function of enzymes, which ultimately has various effects on biochemical activities that take place within the cell. In this case, the hormone acts as the first messenger, whereas the biochemicals that induce cellular changes are referred to as second messengers. Ultimately, the changes that occur within the cell are recognized as a response to the hormone.

I believe the answer to your question will be D)
We define health as a state of complete physical, social and mental wellbeing, and not merely the absence of disease or infirmity.
From this definition you can see that health has three dimensions – physical, mental and social – which are interrelated and influence each other greatly.
Physical health relates to the efficient functioning of the body and its systems, and includes physical capacity to perform tasks and physical fitness.
Mental health is a state of wellbeing in which an individual:
recognises their own abilitiescan cope with the normal stresses of lifecan work productively and fruitfullyis able to contribute to their community.
Social health involves being able to interact with others and participate in the community in both an independent and cooperative manner.
Some examples of how events can influence all dimensions of health:
Example 1: A 16 year old male is involved in a car accident and breaks his pelvis, rendering him unable to attend school, or play football with the local club he loves.
His physical health is affected by the damage done to his pelvic bones and a loss of fitness, which in turn has prevented him from maintaining social contact at school and football, decreasing his ability to interact with others and have good social health. His isolation may also reduce his mental health as he may feel lonely and depressed.
Example 2: A 33 year old woman develops depression.
Depression causes feelings of hopelessness, stress and loss of interest in normal activities, negatively impacting her mental health. This may decrease her desire to exercise or prepare healthy food, leading to weight gain and loss of fitness, reducing her physical health. Her depression may mean that she isn’t interested in interacting with others and participating in her community, and her moodiness puts a strain on her relationship with her husband, reducing her social health.
The stage of physical development during adolescence is called puberty!
Answer: C.early majority-use mass media to directly reach out to large numbers in priority populations
Explanation:
Diffusion theory of innovation suggests that how, why and at what rate the new ideas, opinions, technology and innovations spread among public from the innovators. The theory suggests that there are four main elements that influence the spread of the new ideas, innovations by itself, through communication channels, and via social system.
According to the given situation, mass media can reach upto a large mass worldwide and can spread the information about the tool for breast cancer. This is likely to remove any kind of doubts and will promote the sales according to the needs of the priority patients worldwide.
